METHOD FOR CONTINUOUS METAL POURING Russian patent published in 1994 - IPC

FIELD: metallurgy. SUBSTANCE: method includes metal supply into crystallizer, pulling of ingot from it with variable speed, supply of slag mixture to metal meniscus in the crystallizer, cooling of crystallizer by flowing water, supporting and direction of ingot by means of rollers, cooling of ingot surface by coolant is to be sprayed by injectors, measurement of ingot surface temperature and removal of scale and slag layer from ingot surface. During continuous pouring scale is removed periodical in 0.5-10.0 min and the temperature of ingot surface is measured with scale and after its removal. Received temperature values are compared. At their deviation from optimum values of temperatures difference within the limits of 40-60 C water consumption in crystallizer is changed for 2-4% from working value for each 4-6 C deviation of the mentioned temperatures difference from optimum value. At increase of difference above 40-60 C water consumption is decreased and at decrease of difference below 40-60 C consamption of cooling water is increased. EFFECT: improved quality of ingots. 1 tbl
