Abstract

The invention provides a basic automatic rolled steel plate rapid cooling system for online solid solution treatment and belongs to the technical filed of metallurgy. The basic automatic rolled steel plate rapid cooling system comprises a basic automatic system body which is provided with a rapid cooling water treatment system and a hydraulic system and can be used for online solution treatment of steel of relevant types. According to the basic automatic rolled steel plate rapid cooling system, through the arrangement of the reasonable basic automatic system body provided with the water treatment system and the hydraulic system, full-automatic accurate control over the cooling process is achieved. According to the basic automatic rolled steel plate rapid cooling system for online solid solution treatment, the investment is small, a cooling device is compact and capable of saving energy, the cooling rate is high, the range of the thicknesses of steel plates which can be cooled in a controlled mode is wide, the automatic control precision is high, and the plate shape after cooling is good.

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 ...
