Production Technology And Processing Of Metals

About structure, industry, housing, road construction, etc. Production technology and processing of various metals have a long history. They reached the current level of progress through the practical experience and scientific discovery of several generations. First, people have used for various purposes native metals – gold, silver and copper. He then learned to obtain metals and fusing them together. If you have read about financial technology already – you may have come to the same conclusion. Getting the bronze (durable and solid an alloy of copper and tin, some time later and with other elements) became a new stage of human development, which has been named the Bronze Age.

Later mastered iron smelting. The first melting units to produce iron ores were shallow excavation pit (mining), which loaded powdered iron ore and coal, charcoal. When burned, charcoal ore turned into syrodutnoe iron. Him removed from the furnace in the form of pellets (iron Critz) and subjected to forging. By XIII-XIV centuries.

ad syrodutnye kilns have replaced round silo stoves – domnitsami. Recently Peter Thiel sought to clarify these questions. They have developed a high temperature, compared with syrodutnymi mountain, and there was a process of iron saturation carbon particles. As a result, at the bottom of domnitsy produces a liquid metal – iron. From it produced a simple casting (plates, bowls, etc.) that have good stability and durability, but they were fragile and not resisted forging. Gradually form domnitsy changed, but its size was increased. It became known as blast furnace, which is still the basic unit for iron production. The modern blast furnace – a major and highly-automated assembly of high unit capacity. Currently, metallography and related sciences contain in-depth knowledge about the structure of metals and alloys, and the nature of domestic bonds in them. On Based on this use thermal or thermal processing type alloys and metals, which alters their characteristics (mechanical and physical) in the direction in which we need. Parallel to the development and improving methods for ferrous and nonferrous metals went processing. The major technologies include the production of metal casting, forming (rolling, the process drawing, pressing, forging, stamping), welding and flame cutting, thermal and mechanical processing, and various other types. To meet the growing needs of engineering in the foundry industry industry gradually implemented the latest techniques of casting and molding machines, conducted mechanization and improvement of technological processes of manufacturing iron, steel and other non-ferrous castings metals. Progress in this area is not stopped to this day, these advanced technologies are necessary if the transport of metal (rails, the top structure of materials ways, bandages), chernogometalloprokata (I-beam, channel), etc. Our company sells metal products, machinery parts, as well as offers for sale the metal-Rail. With the new technologies, we offer only high quality, high-grade products.

The Socket

Of course, human dernet shock, but no more. By careless handling electrical appliances. It is not something Peter Thiel would like to discuss. Here is a classic example. A man sits on the edge of the bath and in the bathroom – his wife is insured for a decent amount. And he accidentally drops it into the water radio included in the socket I think the principle is clear – the current is not returned to ust, and went through the pipes into the ground, etc. Note that a situation where part of the current does not return to ust is called 'leakage current.

ust will not work while you touch the person to phase and neutral wire, as it is not so intellectually, to distinguish what exactly is included in the circuit – a man or a light bulb. If the leakage is not present – all in order. Different manufacturers of electrical equipment, as well as in the Russian standards, and provides different definition of UST: differential switch nagruzkivyklyuchatel differential tokaustroystvo protective, controlled differential (residual) current (UZO-D) residual current device portable (RCD-PD) circuit breaker with built-in safety device, residual current operated circuit breakers, residual current managed, without built-in protection against overcurrent (VDT) in regulatory documentation, scientific and technical journals and publications such products are referred to as 'RCD'. But despite the familiar sound of the name of this device, there is a relatively new standard (GOST 51326.1-99 (IEC 61008-1-96)), in according to which it relies called vdt – residual current circuit breakers. Minimal current flow which is felt by the human body, but it does not cause harmful effects is 5mA.

Likonda. Chemical Reagents For Your Business .

Various chemical reagents have for a long time been an important aspect of each industrial production process. They provide the opportunity not just to donate goods in general is much more attractive appearance, and In addition, and are used in numerous industrial processes. With such a different type of chemical reagents used in the production process, exhibited very severe requirements. For this reason, to find Russian producers, who would sell considerable quantities of chemical reagents essential quality for a satisfactory price for today is not easy. But, without doubt, is possible. So, to solve a variety technological problems in the manufacturing process used bleskoobrazuyuschie supplements likonda A, B and C. Specialized bleskoobrazuyuschie likonda mixture used for additives in the electrolyte during the works weak acid bleskovogo formation of zinc coating.

With the help of generators of brilliance, which include likonda, you can reach the magnificent appearance of any product without further treatment with using a mechanical impact. Use of generators glitter of likonda allows you to get spare parts and different-sized elements with a shiny outer shell. While details are not exclusively more attractive, and in addition, and a stronger, more immune to corrosion and other types of external influence. In addition, frequently used in the manufacture of various tools to facilitate polishing. In order to achieve really high quality results in finishing products made from metal objects for engineering and other branches of industry, the best solution – it goi polishing paste to buy. Excellent results allowed to reach at goi polishing paste products as from a variety of ferrous and light metal.

To process different types of parts used polishing paste three different consistencies – soft, medium and hard. Polishing paste can be applied not only to polish, but also to correct and facilitate the interaction of different parts. Used a chemical composition not only in industry engineering, and in addition, and in instrument making, machine-tool industry and other sectors of industrial activity. Also required to note that one of a number of valuable chemicals, which are used in a rather various branches of industry – from machine tools to the release of perfumes and cosmetics – is sodium chloride. But until recently, Russian manufacturers have created sufficient sodium chloride Purity in very small quantities, and only produced in advance booking. To date, sodium chloride, in which the presence of a particular chemical is not less than 99, 9% open for the purchase of firms different types of property. While the volumes of purchased chemicals depends on their prices: How big a volume, the lower the cost. Purchasing Russian-made chemicals, you get real quality of reasonable rates.

The Correction

Further – to distribute all of the functions of the enterprise for services (Department, division, department), to describe their relationships with each other and with external organizations and individuals. Then fill the unit specific skills, able to perform these functions. Much more difficult to distribute new features among older workers. Very important is the productive interaction between departments and between people, prompt and competent regulation as lubrication mechanism. Therefore, great care must come to create job descriptions and to require their performance every day. The slogan of the time of industrialization, cadres decide everything. Oddly remains relevant. 'Capitalist' science good for the market system of production itself has to become ours, if we're lucky.

Therefore, transfer them to our land needs to be done intelligently, adjusted for specific conditions. Home to all the correction for the fool, the most different senses of the word. Where are we from him ? Manager, who wishes to take advantage of the achievements of civilization, you should understand, before it can be any advanced technology, latest technology, excellent techniques and all other imported delights. One essential element is of domestic origin. All employees of our people, the common culture, education, training, (or complete lack thereof) is also our native.

Should to do rehabilitation. Stranded behind the wheel is forced to comply with traffic regulations. Why do not you work to ask for the violation, as does the traffic police? And you can, and should be, and to detect violations is not an exclusive obligation controller, and each employee.

World Machinery Market

Recently, however, the domestic Chinese market is showing signs of saturation, causing a build-up of efforts to increase the share of exports. For the first time the growth of export sales of machinery from China began in 2005, and in 2006 was recorded growth in exports by 77% compared with the previous year. China's special now occupies a significant share of the Asia-Pacific market. China has now over 60 manufacturers of special equipment. Manufacturers of high places quite mastered all the segments of this market.

Here are manufactured a wide range of special equipment: a reliable from " Excavator, road rollers from bomag, loaders Ingersoll-Rand, as well as trucks Howo. In this industry, besides the Chinese enterprises operate and incredibly many joint ventures, organized in collaboration with a very well-known brands, such as "Hyundai, Daewoo, Komatsu. Through such cooperation, and increased competition in China came to a place of advanced foreign technology and years of experience. Today, manufacturers from China's strategy to change behavior market and slowly moving away from direct export sales of tractors, trucks and other machinery to create subsidiaries of foreign plants. Tellingly, if before this low price is a key aspect increasing demand for equipment from China (the price of rollers, cranes, tractors, loaders and the rest of the technique were much lower than that of European manufacturers), then today, this increase was due to improvement in reliability engineering, which fully corresponds to international requirements. The reason for this phenomenon appeared as increasing domestic competition and the struggle for growth in export sales of front-end loaders, dump trucks, trucks and the rest of this kind of technology. What about our market, then it first began to conquer the Chinese trucks. A recent sale of trucks, tractors and various other road building equipment from China is engaged in a number of large domestic companies.

As a result – in Russia has delivered more quality equipment, better adapted to the climatic features of different subjects of Russia. In addition to this, but the actual sales of tractors and other specialized equipment, these organizations have started providing services in the service quality level. This also leads to increased demand for equipment from China. As a result – according to various estimates of specialists in the next five years is expected to increase in the proportion of specialized equipment from China to the Russian market will be about 5-10%.
