Automatic production line for producing high-strength color coated package steel strip by utilizing non-tempering process

Abstract

The invention relates the automatic production line producing high-strength colored paint package steel band with non tempering technology, comprising pull-type recoiler, bonding machine, feeding planisher, storage bin, tension speed control S roll units, slitting shears, flat edge trimmer, heating furnace, the first and second cooling trough, coating groove, coating drying furnace, wax or oil groove, drying powder, differential tension speed control S roll units, separate gravity loop units, roll-up units, shipping package units and automatic control system. The roll-up machine comprises adjusting wheel, pressing wheel, nylon wheel, and air-actuated cut, correcting wheel, material received reel and dummy car. The production line makes the whole industrial process on the one production line, and the metallurgical structure of steel band comprises pearlyte and ferrolites. Compared with high-strength package steel band production line at home and abroad, the said production line reduces the cost of manufacture by 40% and equipment investment by 90%.

Description

technical field [0001] The invention belongs to the technical field of packaging steel strip production, in particular to an automatic production line for producing high-strength color-coated packaging steel strips using a non-quenching and tempering process, which is used to produce high-strength color-coated steel strips whose internal organizational structure is pearlite + ferrite Packing strips. Background technique [0002] All steel strips for conventional production of high-strength packaging are made of alloy structural steel or high-quality carbon structural steel (such as 45 # steel, etc.) for quenching, and then through shearing, tempering, coating and other processes to achieve. Quenching is an independent production line, tempering coating is a production line, and the whole process is composed of two production lines. At present, only a few countries in the world can produce this kind of continuous quenching equipment, and the equipment investment is huge, th...
