PURPOSE: To enable small lot production subjected to temp. compensation with heating and having new component series with alloy element addition by holding the temp. of molten metal in a tundish for continuous casting having heating function.
CONSTITUTION: The base molten metal 4 is continuously cast in small lot with the tundish 2 having the heating function 3 (the first stage). The casting into a mold 5 is interrupted while holding the aimed quantity of molten metal 4 in the tundish 2 (the second stage). Alloy elements 7 are added while heating and heat-compensating the molten metal 4 with the heating device 3 (the third stage). The casting is started after obtaining the adequate temp. and the target component values while repeating the process of sampling - analysis - alloy addition (the fourth stage). By this method, the small lot material can be produced with good efficiency about the process stages and energy consumption.
