Description

technical field [0001] The invention belongs to the field of industrial equipment, and in particular relates to a high-efficiency rolling mill and its working method. Background technique [0002] The rolling mill deforms the metal material through strong pressure to obtain the desired shape of the material. Used to make various profiles and blanks. Rolling mill is the equipment that realizes the metal rolling process. It generally refers to the equipment that completes the whole process of rolling material production, including main equipment, auxiliary equipment, lifting and transportation equipment and auxiliary equipment. In order to meet the needs of production and life, human beings need to use a large amount of metal materials. However, the process of making metal materials into a convenient manufacturing process requires the use of rolling mills.

AI Technical Summary

Problems solved by technology

[0003] The structure of the rolling mills on the market is relatively complicated, and the production process of the rolling mills is extremely cumbersome, which leads to high production costs of the rolling mills and a great consumption of resources. It is necessary to heat the metal material entering the rolling mill to make it easy to operate, which leads to the addition of heating machines in the process of rolling steel in the rolling mill. The traditional rolling mill does not include heating devices, so it is often necessary to add engineering machines for heating. There are too many machines in the production line, which makes the operation of workers cumbersome. At the same time, adding heating machines means increasing power consumption and resource consumption, which leads to a great increase in cost. Traditional heating machines use hot oil Oil bath heating or heating for electric heating coils. The heating efficiency of hot oil bath heating is low, and the temperature that can be heated is also low. The heating method of electric heating coils transfers heat to the barrel through contact conduction. The heat on the inner side of the barrel surface can be transferred to the barrel, so that most of the outer heat is lost to the air, there is heat conduction loss, and the ambient temperature rises

The power density of the heating is low, and it cannot be adapted to some heating occasions that require higher temperature

In traditional steel rolling, the distance between the upper and lower rolls needs to be manually adjusted. Due to improper operation and errors, the distance between the upper and lower rolls also produces errors, which makes it difficult for the thickness of the metal material to reach the correct value after rolling. It is difficult to meet the precision requirements of the current industrial manufacturing for metal materials
