PURPOSE:To obtain a product without any metallurgical defect by supplying liquid having high boiling point at the specific temp. in the inside of sleeve of cooling drums and cooling softly a strip formed from molten metal through the sleeve. CONSTITUTION:The liquid (b) having high boiling point in a tank 15 is heated to raise the temp. by a heater 16 as measuring by a thermometer 17 and sup plied into the cooling drums 10, 10 through an inlet side of piping 11a by driving a pump 13 and started to circulate into the tank 15 through an outlet side of piping 11b. By changing over to control of electric source 19 by a temp. detector 12 and a temp. indicating adjuster 17, the heater 16 is controlled, to supply continuously the liquid (b) having high boiling point into the cooling drums 10, 10 as adjusting 80-200 deg.C the liquid temp. In this way, by the liquid (b) having high boiling point at 80-200 deg.C, the molten metal is cooled and solidi fied through the sleeve 3, 3 and the strip is continuously cast as cooling and solidifying by slow cooling. |
