Ukuthi ulayini lwesithando somlilo lunemifantu |
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 | Bheka ukuthi ingabe kukhona yini ukuqhekeka empambanweni yohlangothi egwema ulayini lwesithando somlilo kanye nembobo yompompi | Ngesikhathi sokukhulelwa | Uma kuvela imifantu, yilungise | |
| Furnace lining repair at furnace bottom and slag line | Bheka ngamehlo engqondo ukuthi ulayini lwesithando somlilo ngaphansi kwesithando somlilo kanye nomugqa we-slag ugqwalile yini endaweni | Ngemva kokusakaza | If there is obvious corrosion, it needs to be repaired | |
