World War Industrial

And in this case for the production of silicon is used mainly charcoal. The important role played by the production of activated carbons. Activated coal – a product with well-developed inner surface. As an adsorbent charcoal used in the food industry to clean vodka, sugar and some other products. See JPMorgan Chase for more details and insights. Activated carbons are used for vapor recovery of many solvents from the air ventilation systems and industrial premises for the detention of airborne hazardous and toxic contaminants (industrial and military gas masks).

On ships Activated carbon filters are filled with cleaning wastewater. It is used to separate salts of metals, including precious, from solutions of low concentrations, for cleaning industrial waste and gas emissions, for regeneration of water and air in a closed cycle, such as in space and in submarines, for desalination and other purposes. Production carburizing has played an important defense role during World War ii. Then interest in this area of coal utilization weakened and revived only in the second half of the twentieth century. Charcoal is also used in medicine and agriculture. Sorbitsionnye properties of coal used in the treatment of Some of poisoning and gastro-intestinal diseases. In medical applications of it are made pills or powders for oral administration.

In agriculture, crushed charcoal is introduced into the diet of birds, pigs, calves cattle. Coal dust injected into the soil at planting roots and bulbs. This is a cheap and highly effective way to fight plant diseases. Coal production for domestic purposes in recent years has greatly increased and tends to further growth.

Universal bending machine can be used for bending pipes: – water and gas steel pipes, gost 3262 – 75. – (Diameter 1 / 2''to 2 ', the wall thickness from 2,5 to 4,5 mm), grade of steel from the CT-3 to CT-45 – seamless steel pipe cold, gost 8734-75 (d 20 to 60 mm, wall thickness from 2 to 5 mm), grade of steel from the CT-3 to CT-20 – hot-rolled seamless steel pipes, gost 8732-70 (d 25 to 60 mm, wall thickness from 2,5 to 5 mm) steel grades either – seamless, cold and warm tubes of corrosion resistant (stainless) steel, gost 9941-81 (the outer diameter of 20 to 60 mm, wall thickness from 2 to 5 mm), steel grade, any gost 5632-72; welded tubes from carbon and steel, gost 10704-76, gost 11068-8 (d 25 to 60 mm wall thickness from 2,5 to 5 mm), grade of steel from the CT-3 to CT-20; 08Cr18Ni10Ti, 12X18H10T, 10X17H13M2T etc. – seamless tubes for engineering purposes according to tu 14-157-35-94 (d 25 to 60 mm thick wall from 2.5 to 5 mm), steel grade, any of the CT-3 to CT-45 – boiler pipes tu 14-3-460-75 (d 20 to 60 mm wall thickness from 2 to 5 mm), grade steel 12H1MF, 20X – copper pipes gost 617-90 (d 20 to 60 mm, wall thickness from 2 to 5 mm) – brass tubes gost 494-90 (d 20 to 60 mm, wall thickness from 2 to 5 mm) – shaped pipes gost 8639-57, gost 8645-57, (steel grade any of the CT-3 to CT-45, size 16 to 50 mm, wall thickness from 1,5 to 3,5 mm)

Welding

Welding – is one of the leading technological processes of metal. The big advantages of welding ensured its widespread use in the economy. With welding being carried out ships, turbines, boilers, planes, bridges, reactors and other necessary structures. The ability of metal welded open man even during the initial development of this material. Nuggets metal man is regarded as original stones that do not break up upon impact, and crushed.

Therefore, the first method of metal was cold forging. The greatest volume among other types of welding is manual arc welding – Fusion welding mma welding electrodes, at which the feed electrode and moving the arc along the welded edges manually. The main working tool for manual welder welding electrode is that intended for clamping the welding electrode and wire welding current. Applied electrode spring, plate and screw types. For automatic submerged arc welding using bare welding wire and flux for the protection of the arc and weld pool from the air.

Feeding and movement of the electrode wire and the ignition process of arc welding and crater at the end of the suture is automated. In the process of automatic submerged-arc welding arc burns between the welding wire and base metal. Submerged arc welding operates welding machines, welding heads or self-propelled tractors, moving directly from product. Appointment of welding machines – welding wire feeding into the arc and continuous welding mode during the entire process.
