Method of rolling finished sections from a preliminary section |
摘要 |
A method of rolling finished sections from a preliminary section by initially carrying out five or more passes and reversing passes between a universal stand and a horizontal stand, wherein profiled horizontal rolls of the universal stand form in the section two indentations located opposite of each other and offset relative to a longitudinal center of the section. Subsequently, head and flange projections of an emerging rail section are preshaped and the indentations are laterally reduced by one of alternative grooves of a horizontal stand of a preliminary rolling group. The emerging rail section is rolled in a reversing operation after three or more passes in the universal stand and in two alternative grooves of an intermediate upsetting stand. The section is finish-rolled into a rail section in an additional pass through the universal stand.
