Material processing stress on-line removal and straightening and cutting technology

Abstract

The invention discloses a process for online removal of material processing stress and straightening and cutting. The tube furnace is tempered, the length of the tube furnace is 8 meters, the heat treatment temperature is 900°C, and the wire speed of the stainless steel wire rod is 4-5m / min. The present invention can realize online removal of processing stress, save working time, improve work efficiency, and the cooling is no longer simply air cooling or water cooling, and adopts an in-between method, which not only solves the problem of low cooling efficiency of air cooling It also prevents the problem that water cooling makes the material too hardened by cold work; this process can be well matched with the continuous method of on-line rolling and on-line heat treatment of stainless steel products, with less processing time and high processing efficiency.

Description

technical field [0001] The invention relates to a technology for online removal of material processing stress and straightening and cutting. Background technique [0002] During the processing of metal materials, there will inevitably be heat treatment and cooling processes, and processing stress will be generated during processing. At present, the way to remove stress is generally to remove stress after processing semi-finished products. Anti-rolling, not to mention the low efficiency, a certain amount of winding tension will be generated during the winding and anti-rolling process. The patent with the publication number CN208450263U: a straightening and adjusting device for processing stainless steel wire rods, including a base on which a rotating drum is arranged; one end of the rotating drum is extended and connected to a forward and reverse motor; Several straightening discs and cleaning frames are arranged alternately on the rotating cylinder; a sliding sleeve is arra...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects in the prior art, and provide a process for online removal of material processing stress and straightening and cutting, which can realize online removal of processing stress, save working hours, improve work efficiency, and solve both It solves the problem of low cooling efficiency of air cooling, and also prevents the problem of too much cold work hardening of materials caused by water cooling; this process can be well matched with the continuous method of on-line rolling and on-line heat treatment of stainless steel products, with less processing time and high processing efficiency
