FORCEDLY COOLING METHOD FOR LADLE SLAG LINE

摘要

PURPOSE:To provide an increase of the service times of a ladle, by disposing a cooling member near the slag line of the side wall of a ladle then passing a refrigerant to the cooling member to forcibly cool the slag line. CONSTITUTION:Refractories of the ladle dynamically contact the slag 7 in a high temp. state. A cooling box 9 is mounted in the position near the slag line of the refractory brick 2 of the side wall and is directory or indirectly contacted with the slag 7. The size in the vertical direction of the cooling box 9 is made adequately larger than the distance between the top and bottom surfaces of the slag 7. The box 9 is made of copper and the cooling water is circulated therein to increase the cooling capacity. The life of the refractories 2 is extended and the service times of the ladle are increased by the above- mentioned method. The consumption of the refractories is improved as well.
