Optimizing cooling capacity of continuous steel-casting mold, adjusts flow velocity of coolant and available cross section, as function of height in mold

摘要

Flow velocity of coolant passed down through mold channels or bores is controlled. High in the mold, where the cross sectional area is smaller, velocity is increased. Lower down, where the cross sectional area is greater, it is reduced. Alternatively or in addition, coverage by coolant is adjusted by a cross section varying with height. An Independent claim is included for the corresponding continuous casting equipment.
