Description

Technical Field

[0001] The invention relates to the technical field of section steel processing and production, in particular to a gas-liquid separation and recovery device for section steel processing and production. Background Art

[0002] Steel is one of the four major types of steel (plate, tube, profile, wire). Steel is divided into simple section steel and complex section steel (special-shaped steel). During the production process of steel, it is necessary to quench the steel. The quenching of steel is a heat treatment process that heats the steel to a temperature above the critical temperature, keeps it warm for a period of time, and then cools it at a cooling rate greater than the critical cooling rate to perform a transformation.

[0003] High-quality profiles are made of high-quality steel, including hot-rolled (forged) high-quality profiles, cold-drawn (pulled) high-quality profiles and other varieties.

[0004] At present, a large amount of water vapor will be generated during the quenching process of steel sections. The water vapor generated by the quenching mechanism during the quenching process is directly discharged into the air and cannot be recycled, resulting in serious waste of resources. At the same time, after long-term processing, a large amount of solid impurities will be generated inside, and the internal impurities need to be cleaned and maintained regularly. The cleaning and maintenance process will affect the processing and production, resulting in high later processing costs. Summary of the invention
