Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to an on-line solid solution treatment after steel plate rolling. Background technique [0002] Solution heat treatment refers to the heat treatment process in which the alloy is heated to a high-temperature single-phase region and maintained at a constant temperature, so that the excess phase is fully dissolved into the solid solution and then rapidly cooled to obtain a supersaturated solid solution. Mainly to improve the plasticity and toughness of steel and alloys, to prepare for precipitation hardening treatment, etc. It can fully dissolve various phases in the alloy, strengthen the solid solution, improve toughness and corrosion resistance, relieve stress and soften, so as to continue processing or forming. Suitable for many special steels, especially high manganese steel and austenitic stainless steel. For alloys with low supersaturation, faster cooling rates ...

Problems solved by technology

[0012] The above-mentioned patented technology has a good effect on solving the basic automatic control problem of off-line heat treatment and quenching, but the basic automatic control system of on-line post-rolling cooling is much more complicated than off-line heat treatment and quenching. Design a complete water treatment system and hydraulic system The basic automatic control system is the key to realize the automatic and precise control of on-line post-rolling cooling
