METHOD OF CASTING WITH FURTHER ROLLING, WHEN HIGH SPEEDS OF CASTING ARE PROVIDED, AND FURTHER HOT ROLLING OF RELATIVELY THIN METAL STOCKS, IN PARTICULAR, STEEL ONES, AND SUITABLE DEVICE

摘要

FIELD: technological processes; metallurgy.;SUBSTANCE: method includes casting with further rolling with control of working rollers temperature. Accuracy of finishing temperature is provided by the fact that at casting speeds from approximately 4 m/min to 12 m/min temperature of working rollers, starting from low initial temperature, is increased with specified increase value, and temperature of strip in line of finish rolling is provided by adjustment or control of rollers cooling intensity equal to specified temperature of heated strip. Device is arranged so that working rollers at the length suitable for increase of temperature and supports of working rollers are arranged as cooled and are connected to system of circular oil lubrication or are lubricated by special fat.;EFFECT: reduction of heated strip temperature losses.;29 cl, 5 dwg
