Hot coil box for hot rolling of super austenite corrosion-resistant stainless steel

Abstract

A hot coil box for hot rolling of super austenite corrosion-resistant stainless steel comprises two vertical plates, the opposite faces of the two vertical plates are each provided with a sliding groove set, each sliding groove set is composed of a front sliding groove and a rear sliding groove, a lead screw is arranged in each sliding groove in a matched mode, a nut is arranged on each lead screw in a threaded fit mode, and a long strip block is movably installed on the inner side of each nut. Long strip grooves are formed in the inner sides of the long strip blocks, moving blocks and control mechanisms for controlling the moving blocks to move are arranged in the long strip grooves in a matched mode, an upper bending roller is movably installed between the two moving blocks located on the same transverse line, and air cylinders are fixedly installed on the opposite faces of the two vertical plates correspondingly; the front end and the rear end of the bottom end of the movable end of each air cylinder are each fixedly provided with an inclined spring telescopic rod, and a lower bending roller with a motor is movably installed between the opposite faces of the two vertical plates. The requirement for adjusting the size of the steel billet is met, the cleaning effect can be achieved, manual cleaning is not needed, the fatigue intensity of workers is relieved, danger is avoided, and functions are diversified in use.

Description

technical field [0001] The invention belongs to the technical field of industrial equipment, in particular to a hot coil box for hot rolling of super austenitic corrosion-resistant stainless steel. Background technique [0002] The hot coil box is the key equipment to improve the quality of hot tandem rolling products. It is more important to match the speed of the rolling mill and the roller table, which directly affects the stability of the entire production line and product quality. A reasonable speed matching relationship can stabilize production and improve efficiency. And product quality is very important, but there will be accumulation of impurities in the bending place of the hot coil box. Excessive accumulation will affect the normal use of the equipment, and it needs to be cleaned up, which reduces the production efficiency. SUMMARY OF THE INVENTION [0003] The present invention provides a hot coil box for hot rolling of super austenitic corrosion-resistant stai...
