Gongyi City, Di Metallurgical Equipment Co., built in 1978, steel cutting machine, located between Zhengzhou, capital of Henan Province and nine in the ancient city of Luoyang, the Longhai Railway, 310 State Road, Lin Huo high speed across the territory, the Wuhan steel cutting machine, transportation very convenient. Gongyi City, Di Metallurgical Equipment Co., Ltd. is engaged in a new cold-rolled steel equipment, development, manufacture of professional manufacturers, can ask you to provide the products are: cold rolling mill, cold-rolled ribbed steel bar production line (equipment, units), the new cold rolled steel production line two ribs, three steel straightening machine, cold rolled and twisted, hot-rolled-up machine, straightening machine, steel cold rolling machines and other equipment to extend. Finishing rebar anchor in order to solve problems connected with large-diameter, high-strength steel reinforcement, we have successfully developed finishing rebar. It is rolling out the reinforced steel surface directly without longitudinal bars and transverse ribs of the trapezoidal shape of the fastener can be used to take a long connection sleeve, with special nuts as anchor. This was in large prestressed reinforced concrete structure, bridge structure used to be successful. Key words: cold rolling mill | cold rolling mill | cold rolled and twisted | cold-rolled ribbed steel equipment | cold-rolled ribbed steel bar production line | cold-rolled steel production line costal Webmaster Statistics in general, cold-rolled ribbed steel bars are small diameter It is the common wire of the cold extrusion. After plastic deformation, Dalian steel cutter, a sharp increase in strength, and ductility was drastically reduced, thus giving rise to the kind of situation you say. Carbon 2% (by mass) or less steel, more than 2 percent of iron. Iron wrought iron of high carbon content ratio, the higher the carbon content, the greater the hardness, toughness worse. Iron is not ideal any substance containing impurities. Iron generally refers to the carbon content of 2 to 4.3 percent of the iron alloy. Also known as cast iron. Pig iron in addition to carbon, also contain silicon, manganese, and a small amount of sulfur, phosphorus, etc., it can not be wrought cast. According to the different forms of pig iron in the presence of carbon, can be divided into steel-making pig iron, cast iron and ductile iron and so are several. Steelmaking pig iron in the form of iron carbide carbon mainly exists, plate element steel cutting machine, which section was white, usually known as white iron. This performance is hard and brittle pig iron, are generally used as raw material for steel making. Foundry iron in carbon flake graphite morphology to exist, it's fracture is gray, usually known as gray iron. Because graphite is soft, it has a lubricating effect, which cast iron has good cutting, wear and casting properties. But its anti-bit strong enough, it can not be wrought only be used in the manufacture of various items, such as casting a variety of machine bed seat, iron tubes. Ductile iron with spherical graphite carbon in the form of existence, and is close to steel and its mechanical properties far better than gray iron, it has excellent casting, machining and wear, have a certain flexibility, widely used in the manufacture of the crankshaft, gears, pistons and other senior casting and a variety of mechanical parts. In addition to silicon, manganese, nickel or other elements particularly high amount of iron, called iron alloy, such as ferrosilicon, ferromanganese, etc., often used for steelmaking raw materials. Adding some alloys in steel making pig iron, can improve the properties of steel. Baotou steel cutting machine, Kindi metallurgy (online consultation), steel cutting machine provided by Di Metallurgical Equipment Co. Di Metallurgical Equipment Co., Ltd. (www.ye-jin.com) is Zhengzhou, reinforced and prestressed machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs .
