Title: Cleaning method for nozzle for continuous casting
Inventor: SASAI KATSUHIRO
IPC: B22D11/10
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To cast a steel raw material to be machined which has no inclusion defect stably at any time and prevent the operability after oxygen opening from decreasing by blowing reducing gas or mixed gas of reducing gas and inert gas after the oxygen opening at nozzle closing time. SOLUTION: When a dipping nozzle 3 is closed, the injection of molten metal into a mold 4 is stopped and the level of the molten metal is lowered to expose a discharge opening 6. The tip part of a refractory pipe 7 for blowing oxygen is put in the discharge opening 6 to blow oxygen to sticking bodies 8, thereby dissolving them away. Then the oxygen-blowing refractory pipe 8 is used to blow the reducing gas to the part cleaned with the oxygen, thereby performing a reduction treatment for iron oxide. Then the injection of molten metal into the mold 4 is restarted to make a speedy return to the normal casting state. Therefore, deterioration in quality owing to the oxygen opening at the nozzle closing time can be prevented and subsequent nozzle closure is reducible.
