Wear characteristic of rolls used for section mills
wear characteristic of rolls used for section mills is unique: the wear value of the bottom of the pass is greater than that of the side wall. The wear of rolls is obviously uneven.
due to the particularity of section steel rolling, the three-dimensional deformation in the roll groove leads to the difference in the sliding speed of different parts of the billets and the uneven deformation of the rolled part. The hardness distribution of roll surface is uneven due to the difference of roll material and production technology. The difference of cooling conditions makes the surface temperature distribution of the rolled parts uneven.
the surface strengthening process of the roll used in section mill can be formulated according to the wear characteristics of the roll surface.
