Learn about the benefits of slitting rolling on the quality Steel rolling mill production line
There are many rolling forms of the quality Steel rolling mill production line. Cross-rolling and split rolling are special parts. Compared with traditional rolling methods, they have many advantages. Let’s look at them first. What is the cross rolling of the rolling mill, and then understand the benefits of slit rolling on the quality Steel rolling mill production line.
When the quality Steel rolling mill production line adopts the cross-rolling forming technology, the axes of the two work rolls of the equipment are kept parallel, and their rotation directions are also the same; the axes of the rolling stock and the rolls are parallel to each other, but the rotation On the other hand, it is the opposite of the roll, so special devices are required for feeding and discharging. There are two types of cross-rolling in the rolling mill. One is that the roll pass is constant along the axial direction and periodically changes along the radial direction. The rolling piece is mainly formed by radial deformation. The other type is that on the surfaces of two or three rolls or two flat plates arranged in parallel with each other, protruding deformed wedges of the same shape are installed, so that the rolling pass is gradually widened in the axial direction.
When other conditions are the same, the split rolling of the quality Steel rolling mill production line is also much better than the general rolling form, which can not only reduce the heating temperature of the billet, save energy, and reduce production costs; This is because the two wires are bitten at the same time after cutting, the cross section changes little, and the temperature difference between the head and the tail is small and the load is even. Using the same size of billets to produce products of the same specification, only half the section is required for the slitting rolling of the rolling mill, thus reducing the number of rolling passes; at the same time, double or multi-line rolling is realized, which greatly increases the output of the rolling mill. , which is very critical for the production of small-scale products.
In addition, in the process of slitting and rolling on the quality Steel rolling mill production line, on-line size detection can be realized, and the unidirectionality and anti-interference of the laser are better than any other light waves, so that the dimensional accuracy of the rolled piece has been significantly improved .
