The Leveler in Cold-Rolling Mills
In the production of cold-rolled steel, a major operation is the insertion of the flat-rolled steel strip between two work rolls, which are the key elements of the mill. This process is known as leveling and it shapes the steel into a finished product. In order to ensure the success of the process, the leveling must be carefully planned and executed with precision.
The work rolls used in cold-rolling mills can be divided into two main type: leveler and straightener. Levelers are used to ensure that the strip is perfectly flat and therefore, it is essential that they are well adjusted before the rolls start to work. This means that the leveler must have a precise level setting and must be able to consistently determine this setting throughout the process.
The leveler used in cold-rolling mills usually consists of a pair of rolls, which can either be driven by a pair of individual motors or by a single motor with a gear drive. The rolls are usually made of single-piece, tempered steel and they rotate at the same speed. The rolls are designed to have a rough, coarse surface in order to grip the steel strip firmly and prevent any slipping or distorting during the process.
In order to ensure the proper operation of the leveler, the rolls must be at an exact, precise level. This level can be set using a set of vertical adjustment screws on the top of the rolls. It is important to note that the adjustment screws should be adjusted very slowly and carefully in order to ensure that the leveler is correctly set and ready for the process.
After the leveler is correctly set, the steel strip is fed through the rolls by a series of rollers which rotate with the leveler. This ensures that the strip is kept firmly in place and also helps to keep the leveler as level as possible. The strip passes through the leveler only a few times, usually just enough to ensure that it is flat. Once the steel strip has been leveled and the process is complete, it can then be cut into the desired length and width.
The leveler is essential in cold-rolling mills and it is one of the most important pieces of equipment in the process. By ensuring that the steel strip is perfectly flat, you will be able to get the best possible results in your cold- rolled steel production. With the right adjustment, the leveler can make sure that your steel is perfectly shaped and ready for use in any commercial application.
