Hot rolling steel can be made into a variety of cross-section forms to meet the needs of service conditions; cold rolling can cause great plastic deformation of the steel, thereby improving the yield point of the steel.
The Advantages and Disadvantages of Hot Rolling and Cold Rolling Read More »
Regardless of hot rolling or cold rolling, the roll is a direct tool to achieve metal deformation during the rolling process. Therefore, the quality requirements of the rolls are strict. Its main quality requirements are strength, hardness, and certain heat resistance.

The low temperature direct rolling technology without heating and compensation is applied to the production line of high strength and anti-seismic steel bars. The typical processes include four-machine four-strand continuous casting machine, out-of-billet roller table, transverse adjusting device and rolling line.

For the installation of rolling mill equipment, there are some small mistakes in the methods mastered by many people. These small mistakes may affect the use of rolling mill equipment. Before installation, we should check whether each part is firm, remove all defects in transportation and storage, clean the parts, decontaminate the rotating parts and fill with grease.

It has been proved by practice that environmental factors are also included in many factors affecting the daily work efficiency of the rolling mill, mainly the humidity and temperature of the environment. Therefore, in order to improve the working efficiency of the rolling mill, the narrow outlet of the heating furnace has strict requirements on humidity. In the case of no tapping, closing the furnace door can reduce air consumption and heat transfer, and reduce the cost of coal or gas.
In recent years, the continuous casting and rolling production lines of some thin slab rolling mill equipment at home and abroad have realized the batch production of thin gauge and ultra-thin gauge hot strip one after another by taking a series of control technologies and measures in the control of molten steel composition, the optimization
