Roll The role of rolls in rolling mill production lines!

　　Rolling mills include main equipment, auxiliary equipment, lifting and transportation equipment, and auxiliary equipment. Each item is very important and indispensable. A rolling mill is a machine that rolls steel between rotating rolls. It is said that rolling mills appeared in Europe in the 14th century. Continuous, automated, specialized, high-quality, and low-consumption are the development trends of modern rolling mills. The rolling mill's working frame is used to install the frame and is fixed to the foundation, also known as the floor. It bears the weight of the working frame and the tilting moment, while ensuring the accuracy of the working frame installation dimensions. So, what does the work of a rolling mill include?

　　The main equipment of a rolling mill is the working frame and the transmission device. The machine base consists of Roll , roll bearings, frame, guide seat, roll adjusting device, upper roll balancing device, and roll changing device. Rolls are an important component of rolls in rolling mills. It uses the pressure generated by a pair or a group of rolls to roll steel. It mainly withstands the impact of rolling dynamic and static loads, wear, and temperature changes. Rolls are divided into hot rolls and cold rolls. The role of rolls in rolling mill production lines is to crush. For example, using a rolling mill to roll a 3mm thick steel plate to 0.5mm thick. The roller materials differ greatly under different working conditions. Generally speaking, it uses materials with high hardness, high strength, and small deformation. In this era of rapid industrial development, people's demand for cutting large steel materials is becoming increasingly urgent, and rolling mills are equipment that realizes metal rolling processes. It generally refers to equipment that completes the entire rolling production process, including main equipment, auxiliary equipment, lifting and transportation equipment, and auxiliary equipment. However, the rolling mill generally refers to the main equipment of the rolling mill. Although current rolls are very suitable for large cutting, they have certain limitations. During use, it will be affected by some factors, causing the rolling mill to malfunction. Please refer to the following analysis for specific factors.

　　First, the large current interference causes the rolling mill to malfunction. Second, the interference of the frequency converter requires us to analyze the principle of these interference factors. Harmonic interference rolling mill. It is said that rolls appeared in Europe in the 14th century, but the equipment at that time was not very perfect. With the development of science and technology, rolling mills have been constantly improved. The rolling mills we analyzed above need to be improved, which is exactly their shortcomings. I believe that rolls will perform better and better in the future. Commonly used hot-rolled materials include 55mn2, 55cr, 60crmnmo, 60simnmo, etc., hot rolling is used for piercing, thick plates, steel processing, etc. 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 surface hardness is not required, only high strength, toughness, and heat resistance are required. Hot Roll Only overall normalizing or quenching is used, and the surface hardness should be HB190~270.
