The use of refractory cement in boiler construction is also very large, and refractory cement is also a refractory castable that we need most. Refractory cement is also called aluminate cement. The raw material of aluminate cement is bauxite and limestone. It is made of calcined, with calcium aluminate as the main component, clinker with alumina content of about 50%, and then ground into hydraulic cementitious material, which is also a kind of special cement. The thermal stability of refractory cement is good. The aggregate is almost all clinker. The expansion and the shrinkage of the cement are low. Therefore, the thermal expansion of the masonry is smaller than that of the brick, the temperature stress is relatively small, and the structure is also various. Reticulated, needle-like, chain-like crystalline phase, strong resistance to air temperature, for example, used to cast soaking furnace mouth and furnace cover, the furnace age can be extended to one and a half years; and the fire resistance of refractory bricks and the same The texture of the refractory brick is similar, but because the refractory cement does not have a net more sintering, the initial blasting shrinks larger, so the load softening point is slightly lower than the refractory brick, but as a whole, the refractory cement is still due to the refractory brick.
The main features of high-efficiency continuous casting mold copper tube material: high-efficiency continuous casting mold material with good thermal conductivity, high recrystallization temperature, high thermal fatigue resistance, high strength, good wear resistance, long service life, high efficiency continuous casting mold copper tube The main feature of the material is that the overall performance of the above properties of the copper tube material is optimal.
In order to improve the wear resistance of the chrome plating layer and prolong the service life of the copper tube of the mold, a nickel-cobalt alloy coating layer of 0.4-0.5 mm thick is added between the inner surface of the copper tube of the crystallizer and the chrome plating layer as a transition layer. Therefore, it is called nickel-cobalt alloy - hard chrome plating. Referred to as composite copper plated tube. The metal content is: the hardness of the coating is 300-600 HV.
Because nickel-cobalt alloy coating has good chemical corrosion resistance, thermal erosion resistance and wear resistance. It not only blocks the diffusion of Zn, S, Cd and F in the molten steel to the inner surface of the copper tube of the mold, but also acts as a binder between the inner surface of the copper tube of the crystallizer and the chrome plating layer, so that the chrome layer is wear-resistant. The performance has been greatly improved. In addition, after the chrome layer is worn, the nickel-cobalt alloy coating can continue to work instead of the chrome layer, thereby prolonging the service life of the crystallizer copper tube.

Rolling mill rolls is a kind of cast iron roll manufactured by using the supercooling of molten iron itself and the quenching of die surface, and adding Ni, Cr, Mo alloy elements at the same time. There is basically no free graphite in the matrix structure of the working layer of the roll body, so it has high hardness and excellent wear resistance.
This kind of material can be used to produce large size rolls by static compound casting process, which makes the roll body have high hardness and the roll neck have high strength and toughness, showing good thermal stability and accident resistance.
Tungsten carbide roll rings has good heat transfer performance, low hardness drop and high thermal fatigue resistance at high temperature
Good wear resistance, high strength, etc. These characteristics are difficult to achieve with other materials. Therefore, since the advent of the high-speed wire rod mill, the tungsten carbide roll rings has emerged as the times require, and has been continuously developed and perfected. It has been widely used for rolling production of high-speed wire rods, bars and rebars.
