Abstract
The invention relates to the direct rolling of stock material with subsequent separation. The heated stock material is progressively rolled in a box pass, in a diamond and diagonal square grooves. After the box pass, the stock material is rolled in a shape slitting pass which is embodied in the form of two ovals fitted with a breaker core. Afterwards, the stock material is rolled in the diamond and diagonal square grooves which are embodied in the form of two hot rolled breakdowns with the breaker core. The separation of two matched diagonal squares is carried out in the slitting pass by means of collar passes having a round shape with a radius R=(0.3-0.45)a; a is a side of the square stock material. The invention improves the quality of rolled stock by preventing twisting of the hot rolled breakdown and by correcting defects of the crystalline structure of an ingot tightening the axial porosity thereof and increases the efficiency of a rolling mill.
