What is calendering processing industry?

Calendering processing industry refers to steel calendering, which is a technological name of steel industry.

Iron and steel rolling processing industry is a name of the national industrial statistical classification, which refers to the iron and steel rolling processing industry, including steel plate, section steel, strip steel, wire rod, cold and hot plate, as well as continuous casting and rolling process. At the same time, calendering is one of the important basic technological processes in the processing of polymer materials, and it is also one of the important processing and molding methods for semi-finished products and finished products of some polymer materials (such as rubber and thermoplastics).

Extended data:

In the calendering process, when the material passes through the gap of the calendering roller, it will be subjected to both shearing force and tensile stress, and the polymer will be oriented in the calendering direction, which makes the product have anisotropic characteristics in physics and mechanics.

The complete calendering process can be divided into two stages: feeding and calendering. The feeding stage is the material preparation stage of calendering, which mainly includes several working procedures, such as material preparation, mixing, plasticizing and feeding into calender. Therefore, the calendering process is actually a complete continuous production line, which goes through various polymer processing steps from raw materials. The control of calendering process is mainly to determine the calendering operating conditions, including roller temperature, roller speed, speed ratio, material storage and roller distance. They are interrelated and restrict each other.
