What is the Universal Mill?
The universal mill is composed of a pair of horizontal rollers and a pair of vertical rollers. The axis of the four rollers is in one plane, the horizontal roller is the driving roller, and the vertical roller is the driven roller (some rolling mill vertical rollers can also be driven). The rolling stock can be processed on four sides, and the two-roll horizontal rolling mill can be used as an auxiliary frame (edger).
The universal rolling mill is mainly used to roll various types of steel, such as H-beam, rail, I-beam, channel steel, steel sheet pile, U-shaped steel, L-shaped steel, unequal angle steel, etc. because it is suitable for many types of steel. The variety of steel is rolled, hence the name “Universal Mill”.
Universal Rolling Mill Features
1. The complex section hole type composed of four rollers can compress the components on the section at the same time, the deformation of the rolled piece is uniform, the speed difference around the section is small, and the internal stress of the rolled piece is small.
2. It is possible to use a roll with a smaller diameter (because it is not necessary to groove on the roll) to roll a product with a higher leg and a wider waist and to have no slope on the inside of both legs. This is difficult to achieve on a conventional two-roll mill.
3. The reduction of the leg and waist of the rolled piece can be adjusted separately, which simplifies the adjustment of the rolling mill during rolling.
4. High rolling precision, less roll wear and lower energy consumption.
