SLIDE GATE PROVIDED WITH GAS BLOWING IN FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a slide gate provided with a function of gas flowing in, capable of preventing the solidification of a molten metal stagnating in a nozzle hole, and surely effecting natural opening of a hole in opening of the hole. SOLUTION: In the slide gate provided with the function of the gas blowing-in, wherein a gas blowing-in brick 9 passed through with many pores 8 for blowing-in gas into a nozzle hole of a stationary plate 3 is insertion-fit in an insertion-fitting hole 7 under the condition that a nozzle hole 5 of a movable plate 6 making slide-contact linearly with a sliding face 4 of the lower face of the stationary plate is completely closed by a sliding face of the stationary plate, the pores are arranged so that the gas blowing-in direction is made to direct to the inner periphery face of the nozzle hole of the stationary plate, and to form an angle of 5-75 deg. against a perpendicular L to the sliding face.
