With the construction more and more needed, the demand of rebar and other steel products are larger and larger. That requires a high efficiency of the steel plant. The continuous casting machine has become to be the prerequisite equipment to improve the production efficiency, reduce the cost, to occupy the market for most steel plants.…
Steel making is to reduce the carbon in pig iron and remove harmful impurities by smelting, and then add appropriate alloying elements according to the requirements of steel properties to make it with excellent properties. Making steel is different from making iron. The main differences between steel and pig iron are as follows: both steel…
Billet is the final product of rolling production line. The quality of billet reflects the maturity of production technology. Today, Judian will introduce the internal quality of billet. The internal quality of billet refers to whether the billet has correct solidification structure, segregation degree, internal cracks, inclusion content and distribution. During the solidification process of…
The rolling pass desisgn when hot rolling is an important part to think about. Usually, there are 3 conditions should be considered. Whether the rolling pass design is appropriate has a decisive influence on the productivity and output of the mill, product quality, energy consumption, and the difficulty of operation. So rolling pass design must…
We will share with you today, about the three basic laws of steel rolling production. The first is the volume invariance law. We know that the law of invariance of mass is objective in nature, mass = density × volume. Therefore, it can be seen that in the process of pressure processing, as long as…
