Hot-rolled Flat Steel Bar is often used on the building materials, you know how it was produced it? Today, manufacturers to give you a good talk about it!
First, single-layer production process. Equipment is simple, hot-rolled Flat Steel Bar using the conductive requirements, although it is relatively resistant to the impact of carbon black, can be weak, low pressure.
Second, the surface coating process. Equipment is simple, is in the hot-rolled Flat Steel Bar inside and outside the surface coated with a layer of anti-static material, so that the pipe to meet the requirements, but the surface of the anti-static material easy to wear, poor safety.
Third, the use of multi-layer composite process. Including three layers of coextrusion, the production process is complex, high cost, refers to the tube inside and outside the anti-static, flame retardant, the middle layer with impact; or internal and external anti-static, flame retardant. Production of hot-rolled Flat Steel Bar quality assurance. Because the high yield, low power consumption per ton of electricity than the furnace down. Molten steel directly cast into billet, omit the billet process, reducing the cost. Continuous casting small billet high scale, to ensure that Flat Steel Bar ruler rate, meet the needs of users. Manufacturing process characteristics The use of electroplating production process, to achieve a high degree of integration of copper and steel.
