Wear-resistant pipe structure and use

Wear-resistant pipes are wear-resistant pipes and tubes, mainly including wear-resistant straight pipes, elbows, tees, size joints, square and round joints, reducers and other structural parts. They are mainly used for conveying abrasive materials such as pneumatic and pumping slurries. As the conveying medium is generally characterized by high hardness, fast flow rate and large flow rate, and the long time in the process of conveying constantly impact, abrasion and corrosion of the pipe wall, so that the pipeline fatigue and gradually wear through, the application of wear-resistant pipe to solve this problem. Wear-resistant pipe is used for engineering wear and tear serious parts of the internal plus a layer of wear-resistant layer of composite pipe, play a role in energy saving and emission reduction, wear-resistant, corrosion-resistant composite pipe. According to the different wear conditions, the wear-resistant pipe lining also has different material choices. There are lined with wear-resistant ceramic pipe; wear-resistant alloy pipe; tortoise shell mesh wear-resistant pipe fittings; steel rubber wear-resistant pipe; steel-plastic wear-resistant pipe; wear-resistant cast stone pipe; wear-resistant self-propagating composite pipeline; rare-earth alloys wear-resistant pipe and so on. Wear-resistant pipe is widely used, has been all over the electric power, metallurgy, coal, petroleum, chemical industry, building materials, machinery and other industries. Wear-resistant pipe conveying abrasive materials, there are wear-resistant pipe wear fast, especially the bend pipe wear faster. When conveying corrosive gases, liquids or solids in wear-resistant pipes, there is the problem that the wear-resistant pipes are corroded and quickly destroyed. When conveying materials with high temperature in wear-resistant pipes, there is a problem that heat-resistant steel pipes are expensive. After the wear-resistant pipes were put on the market, all these problems were solved.

Is the higher hardness of the wear-resistant steel plate the more wear-resistant it is?

The hardness of wear-resistant steel plate is an important standard for measuring its wear resistance. The hardness of wear-resistant steel plate is divided into micro hardness and surface hardness. The microhardness of carbides in the wear-resistant layer of wear-resistant steel plate can reach HVL 700 ~ 2000, and the surface hardness can reach HRC 58 ~ 62. The wear-resistant layer of the steel plate is mainly composed of chromium alloy, and other alloying components such as manganese, molybdenum, niobium, nickel and so on. are also added. The carbides in the metallographic organization are distributed in the form of fibers, and the direction of the fibers is perpendicular to the surface. However, wear-resistant steel plate is not the higher the hardness wear resistance is about good, wear-resistant steel plate hardness is wear-resistant steel plate good abrasion resistance basis, but the relationship between hardness and abrasion resistance is not directly proportional, wear-resistant steel plate will be mainly wear-resistant, because the wear-resistant steel plate has a hard texture, but also has a soft substrate, generally in the process of wear and tear, there will be some shedding off the material, the substance will be integrated into the soft substrate, and it will not surface to cause much damage. If the degree of organization of the matrix is also very high, the shedding off substances in the mutual movement will be abrasive, which will destroy the matrix organization more quickly. In our daily choice of wear-resistant steel plate, need to choose according to their actual working conditions, to remember is not the higher hardness of the more wear-resistant, if it is in the case of stronger impact, or choose a low hardness of manganese steel plate effect is better.

Wear-resistant composite steel plate cladding layer with cracks is qualified?

Cracks on the surface of wear-resistant composite steel plate are normal, and the absence of cracks is not in line with technical requirements. However, most people want the surface cracks of the cladding layer to be large in number, small in shape, irregular in distribution, and the depth of cracks is limited to the cladding layer. Cracks are allowed on the surface of the wear-resistant steel plate, but they shall not penetrate deep into the mother plate. Its main purpose is to ensure the wear resistance of the composite steel plate surfacing layer and the safety of actual use. Unreasonable surfacing process may lead to the formation of continuous, penetrating large cracks on the surface of the composite steel plate. Such large cracks may penetrate deep into the mother plate and cause great harm. The general thickness of the mother plate of the cladding composite steel plate is 10 mm, and the actual toughness zone metal is reduced by about 20 ~ 30% after cladding. If the surface cracks continue to extend downward across the molten layer, the strength of the mother plate will be reduced, and the more serious will lead to the fracture of the composite steel plate. According to relevant research, the more cracks in the cladding layer, the smaller and wider the distribution, the more complete the welding stress release, the smaller the deformation of the mother plate after welding, the safer to use. In addition, if there is no crack or few cracks on the surface of the wear-resistant composite steel plate, it is regarded as a substandard product, because the surface hardness and abrasion resistance of the surfacing layer do not meet the technical requirements.

Wear protection for grinding rollers

Vertical mill (referred to as vertical mill), also known as roller mill, is a modern cement, electric power, coal, chemical industry and other industries widely used a kind of equipment, has nearly a hundred years of development history. In the early stage, due to the limitation of wear-resistant material performance, it can only be used for grinding soft materials, such as coal, gypsum and so on. With the continuous development of materials research and industrial technology, the vertical mill process technology and equipment level has been improved, and its high efficiency, energy saving, environmental protection features make it more and more people's attention. The core part of vertical mill is grinding roll and grinding disk, the roller sleeve on the roller of vertical mill and the disk liner on the grinding disk are the key wear parts of vertical mill, and their quality is directly related to the output, quality and operation cost of vertical mill unit. In order to ensure the service life of the grinding disk, grinding roller, foreign countries use nickel hard 4 # cast iron, hardness in 62 HRC or so, but nickel is a rare precious metal, our country usually after heat treatment of high chromium alloy cast iron, in order to improve the wear resistance of the roller body and the grinding disk and to extend the service life. Wear-resistant cladding technology in the domestic origin in the late 1950s refers to the use of certain properties of alloy materials with the help of certain heat source means of fusion in the surface of the parent material, in order to give the parent material special performance or make the parts to restore the original shape and size of the process, has been developed from simple repair technology for the manufacture of new products, the old product transformation of the important process. Currently commonly used wear-resistant cladding technology is mainly manual cladding (argon arc cladding, MG welding, CO2 gas-shielded cladding, etc.), automatic cladding (open arc cladding, submerged arc cladding, etc.). Compared with other surface technology, surfacing technology creates the highest value of production, energy saving, material saving, environmental protection is also the largest contribution to truly realize the industrial production of "circular economy" and "green remanufacturing". Shenyang Havell produced wear-resistant plate surfacing layer hardness of up to 58-65HRC, both the good toughness of the metal substrate, with high wear resistance and impact resistance; surfacing layer and the substrate interface near the oxide inclusions, cracks, holes and other defects, the surface layer uniform distribution of fine filamentous stress-release cracks, so that the surfacing layer will not occur in the machining process, spalling off the substrate phenomenon, can be processed with good performance; Connection and installation method is simple: can be fixed on the surface of wearable parts by backside plug welding or bolting method to play a good wear-resistant protection, easy maintenance, high chromium wear-resistant cladding plate is applied in the cement vertical mill equipment, after repairing the grinding disc liner, grinding rollers sheath, and its service life than the wear-resistant casting parts to increase by 1-2 times.
