Abstract

The invention provides a thin-strip cast-rolling high-strength steel withdrawal and straightening production line and a withdrawal and straightening process, the thin-strip cast-rolling high-strength steel withdrawal and straightening production line comprises an uncoiling system, a head straightening machine, head cutting equipment, a welding machine, edge cutting equipment, a withdrawal and straightening system, outlet shears and a coiling machine which are arranged in sequence, and the withdrawal and straightening system comprises a withdrawal and straightening machine and a multi-roller straightening machine which are arranged in sequence; a first tension roller is arranged between the withdrawal and straightening machine and the edge cutting device, and a second tension roller is arranged between the multi-roller straightening machine and the outlet shear. By means of the method, the technical problem that the plate shape improving effect is not ideal in the thin-strip cast-rolling high-strength steel production is solved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a thin-strip cast-rolled high-strength steel tension-leveling production line and a tension-leveling process. Background technique [0002] The trimming and straightening process of thin strip cast-rolled high-strength steel is usually as follows: the strip is sent to the uncoiler by the coil trolley, and then sent to the five-roll straightening machine through the uncoiler (usually a retractable shovel head guide). Straightening treatment, the straightened strip head enters the cutting head to cut off the irregular head, and then sews with the treated strip tail of the previous roll in the sewing machine (or welding at the welding machine); Transition crescents are cut out from the edges of two rolls of strip steel with different plate widths, and then pass through the inlet tension roller, the two-bend, one-leveling and tension-leveling machine, and the outlet tension roller...
