Hightech Truck Scales

Every industrial sector, along with agriculture, will not be able to act without weighing equipment. It also applies when delivering goods to warehouses, to the customs of various transport nodes. In our time apply a variety of types of weights depending on their destination and achieve goals. For example, the industry used crane, platform, truck scales and other forms designed to weighing large loads. Thus, the carload scales can accurately indicate the load weight up to 200 m. In general, an accurate weight control to avoid significant extra costs when dealing with suppliers or recipients of goods and related reliability issues, the possible occurrence of emergency cases. Thus, the scale cars are for the most correct account of the mass transported by motor transport products, whose number is rapidly increasing from year to year.

They make it possible to solve many problems both in the sphere of state control and supervision, and in the industrial sector, transport, trade, agriculture economy. First of all, weigh the empty vehicle, or filled with fluid and loose cargoes. Truck scales are available in various shapes and structures depending on their function – weighing technology for stationary or in motion, in whole, or poosno . For the latter, weighing the structure of such devices is then made of several sections. The most important parameters are the weights of motor Weighing and platform size. These criteria and show what kind of vehicle can be weighed in this kind of truck scales. If the cargo is planned to transport over long distances, in this case is reasonable to deliver it by rail. Then, taking into account the traffic better than any operating track scales.

Features of their shape also depends on the kind and method of weighting. Thus, the most accurate, but also the most time consuming, is static weighing of a standing train at gruzopriemnoy platform. There are scales used for weighing go cars (with fluid or loose and hard goods) in the running, at speeds from 3 to 10 km / h. However, at this Weighing slightly higher error of weighing. There is a series of multi-purpose car scales, allows us to combine the above types of weighing goods depending on their shape. Track scales to weigh petroleum products are the foundation pavement design, which gives the opportunity to weigh without uncoupling the four-and eight-axle tank cars with a minuscule error. Libra automobile and wagon consist of the load receptor (1 to 3 sections) and directly measuring device – load cells connected to each other. The length of the sections varies depending on the destination device. The most important a component of the weights used strain gauge measuring weight, one or more sensors connected to a device matching, which compares the received data from multiple sensors, converts the analog signal in a discrete, but also takes into account a correction for air temperature (- 40 C to + 45 C). The most modern and advanced strain gauges, first broadcast digital signal, ensuring the highest accuracy when any conditions. The sensor body weight is sealed, made of stainless steel and filled with inert gas. In order to reduce wear bearing surfaces of the meter are covered with silicon nitride. Now road and track scales equipped with a large set of devices display the weight from simple to complex weighted indicators of independent controllers that send information to a computer network company.

Global Development

The global steel industry for 70 years, were actively seeking and developing processes and assemblies, enabling the metal to produce vnedomennym way from iron ore by using less energy and scarce reducing to acceptable technical and economic parameters. To date, there are a large number of technologies and vnedomennogo cokeless metal production, have been the industrial distribution. Process Romelt received recognition in the market of new metallurgical technologies. But for all its merits would be premature to raise the issue of replacement of blast furnaces of liquid-phase units or combined recovery. Modern metallurgical production with its enormous scale of the existing capacities and the established multi-step metallurgical cycle rather inertial. The elimination or exclusion of one major redistribution is a serious problem. Check out Petra Diamonds for additional information.

Creation and installation of new facilities of liquid-phase reconstruction requires significant initial investment. Therefore, the economic efficiency of most operating blast furnaces, the equipment are highly damped, will be higher than in new plants, despite the lower cost metal past. Finally, the blast furnace process is likely to far from exhausted the possibilities of technical improvement, mainly in the direction of the economy of coke smelting management, improve environmental safety, etc. Therefore, the period of the blast furnace will be determined by the period of service in terms of capital repairs, as well as the lifetime of conjugated sinter plants and coke oven batteries. In addition, the issue of introducing units of liquid-phase recovery is likely to be solved taking into account the specific economic, environmental, geographical conditions of the region and businesses. Accordingly, the real possibility of a wide industrial use of units of liquid-phase recovery can predict not so soon. This does not exclude, however, the rapid introduction of this process in countries with rapidly growing production of metallurgical (India, China) that have the resources (Iron ore, coal). Equally important is the ability to attract private capital to develop compact and less capital-intensive compared with aglodomennym redistribution units of liquid-phase reconstruction.

In Currently misa with nlmk organized in India, a joint company "Sail-Romelt" to promote their development. Already purchased a license for construction of a Romelt for national mineral of India and is developing the appropriate technical design. By order of Vietnam Steel Corporation developed a feasibility study for the construction of such unit. In Russia today Installation Romelt can be effectively used for processing metallurgical waste in order to protect the environment and reduce the deadweight loss of iron. Special provision may take the application process Romelt mini-plant, running on the batch of scrap. Using the original liquid iron from the unit Romelt can reduce its dependence on the supply of plant and scrap price fluctuations and reduce its content of non-ferrous metals in the steel. According to this principle works plant firm Iskor in South Africa, using the liquid iron from the Corex unit. The process of liquid-phase reduction Romelt on its techno-economic and qualitative parameters was highly rated companies Nippon Steel (Japan) and I.S.F. Kaiser (USA), who purchased a license for it. He refers to the considerable scientific and engineering achievements of modern technology and can play a significant role in the future technical and environmental upgrading of metallurgical production. In general, the process of liquid-phase reduction Romelt on its techno-economic and qualitative parameters, of course, refers to significant scientific and engineering achievements of modern metallurgy. According to Russian and foreign experts, this technology can play a significant role in the future technical and environmental upgrading metallurgical production.

Cement

The method is based study on particle size and chemical and mineralogical composition of cement, depending on the strength parameters of cement on the ratio of the size fractions of 0-40 micrometers and 40-80mkm and more – in manufactured according to the traditional technology of cement has a particle size and 200 m. Experiments have shown that when mixing cement mortar pass fines, and larger still in the cement paste and after its conversion into cement stone in the form of inert filler, that is, in fact, about 50% of cement is not used for its intended purpose. The reason for this is the imperfection of grinding units (ball mills) on the cement plant. Are proposed technology is the so-called remilling (activation) nizkomarochnogo cement with the addition of fly ash or sand to chp fineness when sm2/gr 4000-4500., obtaining high-quality high-quality cement and thus savings in the production of concrete up to 50% for the activation of cement milling complex offers the performance of 8, 15 and 25 tons per hour.

The Laboratory

Made a laboratory furniture completely made of metal, that means it has a metal main frame and metal add-on components. Corps laboratory furniture is based on similar metal frame, but the add-on components it produced from chemically laminated chipboard with special impregnation, which gives protection against the effects of moisture and fire. An important difference from the cabinet Laboratory furniture metal is its price. At the equipment laboratory furniture collection of furniture, of course, other things being equal consumer qualities, will cost less than a factor of 1.5-2 than the same set of metal furniture. Here, we encourage you to pay attention to the principle of 'price-quality' and make choices based on it, it is also important to know what research will take place in the laboratory and acquire furniture from that perspective.

The last difference metal laboratory furniture from the cabinet is the time of its manufacture. Corps laboratory furniture is usually 2-3 times faster. But it is true that if you are ordering individual furniture 'under themselves'. When buying a catalog of furniture from the warehouse, similar problems, of course, is not happening. Laboratory furniture is usually sold for a long time, so when choosing a series of laboratory furniture to focus on some important points. The main thing to note – the frame. That's metal frame is the foundation of any piece of laboratory furniture. Welded frame of laboratory furniture has an advantage over precast due to the higher rigidity, structural strength and stability of the geometric dimensions.

The frame must have adjustable supports for leveling tops horizontally in the case of irregularities of the floor in the laboratory. Paint the frame should be carried out using powder coating. When choosing of furniture for the presence of tortsezaschitnoy edge that protects the public part of cpd. Its thickness must be at least three millimeter. Using the manufacturer of laboratory furniture this edge is an indicator of its holdings of special equipment for the manufacture of furniture and ensure that the furniture is not collected by artisanal methods. Range of laboratory furniture in our time is great enough. There are plenty of both domestic and overseas manufacturers. Choice – for you. We hope that our tips will help you in choosing and at least a little help understand this very difficult and important issue in your laboratory equipment.

Forge Welding

It is considered that the age of metal came with the advent of smelting it from ore. Archaeological data show that the earliest smelting and processing of copper ore was in Asia Minor about 700 years ago. Nevertheless, only the Iron Age technique for obtaining one-piece metal compounds reaches a significant development. Purer and denser iron grew by repeatedly recurring operations: heating, welding and forging. It was in those days originated the ability to weld some pieces of iron by heating and subsequent forging.

Using various techniques forge welding wizard, created a complex made of iron and steel. Welding is widely used for increasing the size of workpiece, the compounds of various metals and to give the desired shape of the product. In the VII-III centuries. bc frequently used welding on overhead parts in the manufacture of weapons and utensils (eg, swords, knives, axes and etc.) Most smiths limited welded steel platinum small part to the cutting blade, rarely used welding in which a solid steel plate was placed between two plates of the softer metal. Masters of Kievan Rus in the ninth and thirteenth centuries. in metallurgy and metalworking reached incredible heights. The technical level of craftsmanship is much faster than Western Europe.

Namely, in the Kievan Rus had mastered the production of high-carbon steel. Forge welding is a leading, well designed and disbursed to manufacturing products of iron or steel. Forge welding is used in the manufacture of about 70% of metal products. Mongol-Tatar invasion caused the decline of craft activities in Russia.
