1. What is a bar mill

A bar mill is a device that processes metal materials using a rolling process with several rollers. It can transform metal bars into different shapes and sizes, and occupies an important position in the metal processing industry. A bar mill is usually composed of a drive system, a reducer, a roller mechanism, a shock absorbing mechanism, an operating system, and other parts.

2. Working principle of a bar mill

The bar mill extrude and roll the metal material through several sets of rollers, causing it to undergo plastic deformation and size change, and finally reach the desired shape and size.

The working principle of a bar mill can be divided into three stages:

The first stage is the initial rolling stage, which mainly compresses the metal material through the working rolls and the support rolls, and transforms the material into a thicker strip or disc shape.

The second stage is the intermediate rolling stage, which mainly rolls the compressed strip or disc material again to transform it into the desired shape and size. This stage requires the control of parameters such as roller gap, roller speed and material feed rate to ensure the accuracy and quality of the final product.

The third stage is the sizing stage, which mainly involves cutting the bars to the required length and final processing to ensure that the final product meets the design requirements.

3. Advantages of bar mills

The main advantage of bar mills is that they can produce metal materials of various shapes and sizes, with high production efficiency and production accuracy, and can meet the needs of various metal processing. In addition, bar mills also have the characteristics of simple structure, convenient operation and long service life, and are widely used in machinery manufacturing, aerospace, construction, power and other industries.

In short, bar mills are an important type of several-roll mills, which play a very important role in the metal processing industry. For metal processing companies, it is very important to choose a high-quality and efficient bar mill.
