Abstract

This article deals with the secondary cooling in a continuous caster. In particular, it deals with homogeneity / inhomogeneity in places where surface of slab is partial shielded by rollers and bearing pocket between rollers. Influence of gap between rollers was also considered.Homogeneity of cooling intensity distribution was experimentally studied in two stages (cold and hot tests).In the first stage (cold tests) water flow and water distribution was observed optically using a transparent board with studied surface structures (rollers and bearing pockets).In the second stage (hot tests) the cooling tests with steel plate (fitted with studied structures) were performed. Cooling homogeneity was studied based on temperature distribution of the non-cooled side of sample, which was recorded by infrared camera.

Keywords: steel, continuous caster, cooling homogeneity, measurement, infrared camera
