RollerThe role in the rolling mill production line!

The roll includes the main equipment, auxiliary equipment, lifting and transportation equipment and auxiliary equipment, each of which is very important and indispensable. A roll is a machine that rolls steel between rotating rolls. Rolling mills are said to have appeared in Europe in the 14th century. Continuity, automation, specialization, high quality and low consumption are the development trends of modern rolling mills. The working frame of the rolling mill is used to install the frame and is fixed on the foundation, also known as the floor. To bear the dead weight and dumping moment of the work frame, while ensuring the accuracy of the installation size of the work frame. So, what does the work of the mill include?

The main equipment of the rolling mill is the work frame and the transmission device. The base is providedRollerIt is composed of roller bearing, frame, guide rail seat, roller adjusting device, upper roller balancing device and roller changing device. The roll is an important part of the roll in the rolling mill. It uses the pressure generated by a pair or set of rolls to roll steel. It mainly bears the influence of rolling brake, static load, wear and temperature change. Roll is divided into hot roll and cold roll. The role of the roll in the rolling mill production line is crushing. For example, a 3mm thick steel plate is rolled to a thickness of 0.5mm by a rolling mill. Different working conditions of the roller material is very different. Generally speaking, it uses materials with high hardness, high strength and small deformation. In this era of rapid industrial development, people's demand for large steel cutting is becoming more and more urgent, and the rolling mill is the equipment to realize the metal rolling process. Generally refers to the completion of the whole process of rolling production equipment, including the main equipment, auxiliary equipment, lifting and transportation equipment and auxiliary equipment. But the general said mill often refers to the main equipment of the mill. Although the current roll is very suitable for large cutting, but it has certain limitations. When he is in use, he will be disturbed by some factors, resulting in the normal operation of the mill. Please refer to the following analysis for specific factors.

First, the current interference is large, resulting in the mill can not work properly. The second is the interference of the inverter, which requires us to analyze the principle of these interference factors. Harmonic interference mill. It is said that rolls appeared in Europe in the 14th century, but the equipment at that time was not perfect. With the development of science and technology, the rolling mill is also constantly improving. The above we love to analyze the mill needs to improve, it is his shortcomings. I believe that the roller will play better and better in the future. Commonly used hot-rolled materials are 55mn2, 55cr, 60crmnmo, 60simnmo, etc., hot-rolled for breakdown, thick plate, steel and other processing. It can withstand strong rolling force, severe wear and thermal fatigue effects, and the hot rolling working temperature is high, allowing wear per unit working diameter, so it does not require surface hardness, only high strength, toughness and heat resistance. HeatRollerOnly integral normalizing or quenching shall be adopted, and the surface hardness shall be HB190 ~ 270.
