초록 ▼

Surface defects in rolled steel are remedied by quenching a surface layer of the strand immediately downstream of the caster by transversely differential quenching to match the transverse temperature profile of the strand. The flow rate of the quench spray is differentially adjustable across the wid

대표청구항 ▼

1. In or for use in a continuous casting steel mill having a caster for producing steel castings, severing means downstream of the caster for transversely severing castings emanating from the caster, a reheat furnace downstream of the severing means, and a conveyor for conveying castings from the caster to the reheat furnace;quench apparatus located in-line downstream of the caster and upstream of the reheat furnace for quenching a surface layer of the casting to a selected depth of penetration so as to transform austenite in the surface of the casting to a non-austenitic microstructure, said quench apparatus comprising: (a) an array of spray nozzles arranged in transversely separated groups above and below castings passing therebetween; (b) at least one valve for each group for controlling the amount of spray provided by each group to the castings passing therebetween; (c) a control unit for controlling the valves thereby to regulate the amount of spray provided by each group, in response to selected parameters including casting width and casting speed; thereby to provide transversely differentiated spray to the castings being quenched.
