IMPROVEMENTS RELATING TO REPAIR OF STEEL-MAKING VESSELS

摘要

A plug 4 fitted in the side wall of a steel-making vessel is sealed in place by a crushed refractory material 8. This tends to burn off after a number of pourings of molten steel to create an enlarged approach well. This well can be repaired by inserting a steel pipe 10 having a tapered portion 12 leading to a narrow entry portion 11 so as to seal off the tap hole 5 in the plug 4. The well can then be filled with a refractory material 14 which sinters or fuses with heat to effect the repair. The steel pipe 10 will burn off during a subsequent heating and pouring of molten steel.
