ROLLING METHOD FOR AT LEAST FIRST AND SECOND ROLLING STRANDS

摘要

PROBLEM TO BE SOLVED: To increase the rolling speed of a strand by adjusting the loop length of the rolling strand forming the loop before the original roll stand after rolling by the common roll stand. SOLUTION: Previous to a second rolling strand 2, a first rolling strand 1 is supplied to a last common roll stand 4. Before supplying the second rolling strand 2 to the last common roll stand 4, the length of loop 8 of the first rolling strand is adjusted to near the min. value. This length is desirable to be 10-15% of the max. loop length. Before coming out the first rolling strand 1 from the last common roll stand 4, the length of the loop 8 of the second rolling strand 2 is adjusted to near the max. value. This length is desirable to be 85-90% of the max. loop length. In this way, the variations at the time of biting and coming out of the rolling strands 1, 2, are compensated.
