METHOD OF CONTINUOUS CASTING OF METALS Russian patent published in 1995 - IPC

FIELD: foundry engineering. SUBSTANCE: method includes feeding of metals into crystallizer and temperature measuring of crystallizer working walls along ingot length and perimeter with the help of thermocouples. Temperature is measured at least on two levels of ingot length. Space between levels corresponds to 0,7-1,0 and 1,4-2,2 of ingot thickness from metal meniscus. In the process of casting point of working walls temperature increase for 10-25 per cent of working value at the upper measuring level is detected. In a period equal to l/v_p point of temperature increase at the lower measuring level is detected. In case of its increase for the same value cooler discharge under crystallizer increases for 5-50 per cent of the working value at the length equal to 0,2-6,0 of the ingot thickness. l is space between temperature measuring levels of crystallizer working walls; v_p is working value of ingot drawing speed, m/min. EFFECT: enhanced efficiency. 1 tbl
