The company will be a stable product quality, quality of service and dedication to new and old customers work together, heat-resistant steel prices, for a better future! Resistant steel - sand casting defect analysis of paint coating strength as one of the key technologies of EPC and EPC technology for success plays a vital role. Compared with ordinary sand casting coating, EPC coating, not only to prevent sticky sand, China heat-resistant steel, improve the surface quality, heat-resistant steel, reduce the surface roughness. More importantly, to improve the appearance of strength and stiffness of foam to prevent the transport, sand filling and vibration modeling, look worse damage and deformation, and the molten metal and the mold apart. If the paint is strong enough, when the vibration modeling prone to rupture, leading to the emergence of liquid metal paint broken parts in contact with the casting mold, and the mold were scouring the sand into molten iron to form a coarse defects. Heat-resistant steel - negative pressure eutrophication fast burning shell casting operation essentials of withdrawal pressure and unpacking a fact, in the vacuum state is not air movement, heat only by doing its own thermal conductivity like sandbox external diffusion , pressure vacuum state can only be a waste of energy without contributing to cooling. Only by breaking its negative balance (ie the withdrawal of pressure) and let the cold air from the flask formed a strong flow of fluid through the upper surface of the casting to the searing heat away. Therefore, when after casting is completed, small pieces usually around 1min pressure can rupture the withdrawal, the member or the large range of about 2 ~ 3min pressure may rupture the withdrawal and continue ventilation. THICK special pieces according to their surface solidification time to estimate the dwell time. This will not only help eliminate casting crack, speed up the cooling rate, energy saving, but also helps the coating to peel off. Because in the rapid cooling effect of the strong cold air flow, coating and casting shrinkage factor varies promote its rupture and separation.
