Ⅰ Slow Heat Conduction
1. Not preheating according to the standard procedure.
2. Slag influences heat conduction.
3. The crucible has reached its lifetime.
Ⅱ Corrosion
1. Adding flux when the crucible is empty or with slug. Excessive use of flux.
2. Certain fluxes contain corrosive substances.
3. Fuel containing corrosive substances.
4. Abnormal high-temperature operation may result in glaze layer smelting resembling.
Ⅲ Excessive Oxidation
1. Hoisting or moving irregulary damages glaze layer.
2. Flame in gas furnace dashes against bottom directly.
3. The top of the crucible is not protected and isolated from oxygen by upturned flame in gas furnace.
4. No corresponding electric heating circles around the top or bottom of the crucible.
5. Overheated working temperature.
Ⅳ Top Problems
1. Slags accumulated around the top area or between the top area and the furnace cover.
2. Excessive oxidation on top area.
3. Repeatedly top impacted when feeding.
4. Contacting with some metals with large heat exchanging codfficients.
Ⅴ Explosion
1. Heating rapidly while the crucible has damped during storage or transportation.
2. The added materials are not completely dried.
3. Over rapid heating-up during preheating procedure.
Ⅵ Middle or Bottom Parts Problems
1. The crucible is not installed properly. It should be placed in the middle of the furnace stack smoothly and stably.
2. An improper graphite stand is used.
3. Metal materials overfilled, or metal ingots in the crucible horizontally and diagonally.
4. Leftover slag or molten metal in the crucible.
5. 5.The existence of temperature is big difference inside furnace.
