The difference between hot rolling and cold rolling

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

Effect of element content on properties of cold rolled sheet

NEWS / wanzhigroup

The content range of various elements common in cold rolled plate, and their respective roles Cold rolled sheet is usually used in the manufacture of steel structures, furniture, electrical appliances, metallurgical equipment and so on. The common element content in cold rolled sheet has the following effects on the performance: How to select cold rolled steel ？ The element content of the cold rolled sheet will affect its performance and use, so the appropriate element content should be selected according to the specific working environment and project requirements. When selecting cold-rolled steel plates, we should fully take into account all aspects, such as its tensile strength, toughness, weldability, easy processability
