Composite wear-resistant steel plate, the chemical composition of the alloy wear-resistant layer has a carbon content of 4 to 5%, and the chromium content is divided into two levels: 18 to 30% and 30 to 40%. The volume fraction of Cr7C3 carbide in its metallographic structure Reaching more than 50%, the macro hardness is HRC56~62, and the hardness of chromium carbide is HV1400~1800. Since carbides are distributed vertically in the direction of wear, even compared with cast alloys of the same composition and hardness, the wear resistance is more than doubled.

Compared with traditional wear-resistant linings, which are made by melting and rolling in steel mills, this new type of surfacing wear-resistant lining is produced through cutting and rolling after surfacing. Various wear-resistant lining plates are processed by production processes such as deformation, drilling and welding, such as conveyor lining plates, coal feeder bottom plates/cyclone separator inverted cones and lining plates, wear-resistant blades, etc. The wear-resistant life is comparable to ordinary steel plates Increased by more than 15 times.

Channel steel is a long strip of steel with a groove-shaped cross-section. It belongs to carbon structural steel for construction and machinery. It is a section steel with a complex cross-section. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.

I-beams are mainly divided into ordinary I-beams, light I-beams and wide-flange I-beams. According to the height ratio of the flange to the web, it is divided into wide, medium and narrow wide flange I-beams. The specifications produced by the former two are No. 10-60, that is, the corresponding height is 10 cm-60 cm. At the same height, the light I-beam has narrow flange, thin web and light weight. The wide-flange I-beam is also called H-beam. The cross section is characterized by two legs parallel and no slope inside the legs. It is an economical section steel, which is rolled on a four-high universal rolling mill, so it is also called "universal I-beam". Ordinary I-beams and light I-beams have formed national standards.

Carbon steel pipes are made of high-quality carbon steel such as 10, 20, 30, 35, 45, 16Mn, 5MnV and other low-alloy structural steels, or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steels are hot-rolled or cold-rolled. 10, 20 and other low carbon steel seamless pipes are mainly used for fluid conveying pipelines. Seamless tubes made of medium carbon steel such as 45 and 40Cr are used to manufacture mechanical parts, such as stressed parts of automobiles and tractors. Generally, carbon steel pipes are used to ensure strength and flattening tests. Hot-rolled steel pipes are delivered in a hot-rolled or heat-treated state; cold-rolled steel pipes are delivered in a heat-treated state.
