Whether the furnace lining has cracks

Check for cracks in the crucible Before the furnace starts every time If the crack width is less than 22 mm , it is not necessary to repair it when chips and other things will not be embedded in the crack, and it can still be used. Otherwise, it needs to be patched before it can be used
Repair of taphole Observe whether there are cracks at the junction of the side avoiding furnace lining and the tap hole At the time of tapping If cracks appear, repair them
Furnace lining repair at furnace bottom and slag line Visually observe whether the furnace lining at the bottom of the furnace and the slag line is locally corroded Emva kokudubula Ukuba kukho ukubola okucacileyo, kufuneka kulungiswe
