The difference between hot rolling and cold rolling

NEWS / wanzhigroup

Hot rolling and cold rolling are two common methods for processing metal materials. Their processing processes and product properties after processing are very different. Here are the specific differences: During processing: 1. Processing principle Hot rolling is to heat a metal material to a plastic temperature at a high temperature, and use a large rolling force to plastically deform the material to form the required shape and size. Cold rolling is carried out at room temperature, using large rolling force to cause cold deformation of the material. 2. Different processing temperatures Hot rolling is the processing of metal materials at high temperatures, usually above 1000℃. Cold rolling is the processing

Cold Rolling And Hot Rolling

NEWS / wanzhigroup

Hot Rolling And Cold Rolling Concepts 1.Hot Rolling Hot Rolling is Continuous casting slabs or blooming slabs are used as raw materials, heated by a step-by-step reheating furnace, dephosphorized by high-pressure water, then entered into the roughing mill, and then into the finishing mill after cutting head and tail, and then precisely controlled by computer. After the final rolling, it is coiled by laminar cooling (the cooling rate is precisely controlled by the computer) and coiler to become a direct roll. The curling head and tail of straight hair are often tongue-shaped and fishtail-shaped, and the accuracy of thickness and width is relatively poor, and the crimping often has defects

What are the advantages of electrostatic spraying color plate over ordinary color plate

NEWS / wanzhigroup

Electrostatic spraying color plate has the following advantages: 1. High spraying efficiency: electrostatic spraying uses electrostatic action to charge the coating particles, and then sprays the charged coating particles to the object surface with opposite charge, so the painting task can be completed quickly and the production cost can be reduced. 2. Save paint: electrostatic spraying can effectively spray paint on the surface of the workpiece, will not produce spatter and waste like traditional spraying, so you can save the amount of paint. 3. Environmental protection: in the process of electrostatic spraying, airless nozzles are used to reduce the pollution of aerosol to the surrounding environment and help to protect the ecological environment.
