Chuzhou, Chuzhou shelf square tube square tube manufacturers offer Hongxing Tai Wang 15231769008 landline 0317-3176004 refers to the iron ore into pig iron blast furnace smelting products, mainly used to build steel and steel castings. Normal talking about steel, rolled steel deformity refers to ethnic steel. Steel and pig iron are the basis of iron steel, carbon alloy mainly added elements, collectively known as the iron-carbon alloys. Extrusion: is steel being put in the non-metal sealed squeeze Jane, applying pressure at one end, so that the provisions of the non-metallic extruded from the die hole and get in shape and have the same sense of propriety finished processing methods, multi-colored for the consumption of non- a metal sheet steel, black and white non-metallic, non-metallic steel and non-ferrous steel are introduced briefly explain beforehand Summary black and white non-metallic, steel steel and non-metallic colored basic concepts. 2, the furnace steelmaking pig iron into steel by a certain process of casting, that get steel. 1, black and white refers to iron and non-metallic alloy of iron. Since dividends are malformations and die forgings, consumption profiles, open-foot section of steel billet and other materials commonly used for larger inch. Alloy is an alloy of iron and silicon, manganese, chromium, titanium and other elements of ferroalloy is one of the steelmaking raw material medicine drugs, do steels are steels steelmaking deoxidizer and alloying elements added agents use. Pullout Steel: is already rolling nonmetallic blank (type, pipe, products, etc.) through the die holes to pull aside to reduce the length of the section of the increased processing methods are mostly used as a cold. The main processing approach steel are: rolling: the steel blank by a gap of non-metallic (ethnic shape) on the winding roll, the roll due to the cross section reduction of the compression of the material, the length of the processing approach to increased pressure, which is the consumption of steel The most common way of consumption, consumption of steel is mainly used profiles, sheet, pipe. . Non-standard seamless square and rectangular tube 2, consume large overall approach to steel steel steel processing are processed through pressure, to be processed steel products (billets, ingots, etc.) the onset of plastic deformation. 3, also known as non-ferrous steel colored non-metallic non-metallic, non-metallic means in addition to black and white outside of nonmetallic and alloys, such as copper, tin, lead, zinc, aluminum and brass, bronze, aluminum and bearing alloys. Such as steel, pig iron, ferroalloy, iron and so on. Square and rectangular tube steel is essential for the country to build and achieve the four modernizations secondary career material, the use of a wide range of variety, according to the same cross-sectional shape, deformity dividends profiles, sheet, pipe four categories of steel and non-metallic products, in order to facilitate tissue consumption of steel, ordering supplies and improve management mission, and dividends heavy rail, light rail, heavy sections, medium steel, merchant bar, steel cold-formed steel, high-quality steel, wire, thick steel plate, sheet steel, electrical silicon steel sheet, strip, seamless steel, welded steel, non-metallic products and other varieties. According to the steel with steel processing temperature is not cold and hot working with two kinds of points. Sub-rolled, cold-rolled. Forged Steel: The hammer strikes, force or promise of reciprocating pressure presses the blank change to our desired shape and measured a pressure processing approach. These are known as lightly colored nonmetallic industrial use of non-metallic, non-metallic steel in addition to valuable: platinum, gold, silver and rare non-metallic, including radioactive uranium, radium and other steel products. Information on how to distinguish between square and rectangular tube Rectangular tube information how to distinguish between a concept of steel: Steel is a steel ingot, billet steel or promise made by all ethnic groups in the shape of pressure processing we need, propriety and performance materials. Thus the industry is also used lightly chromium, nickel, manganese, molybdenum, cobalt steel, vanadium, tungsten, titanium, an alloy mainly used for these non-metallic additions to the deterioration of the performance of non-metallic, the process of tungsten, steel, titanium and molybdenum Multi-use carbide tools for consumption. Steel products are ingots, steel billet and direct access cast steel castings and other ethnic groups. Steel steel steel is black and white non-metallic but not exactly black and white non-metallic. The cast iron is placed in the casting cupola that get cast iron (liquid), the liquid cast iron, cast steel castings, the cast is called iron castings. http://www.cz-scg.net/product-16.html
