Feature
1. Advanced technology：The world's most advanced cold isostatic molding method crucible, manufactured products with isotropic properties and a high density, the production of crucible material dense uniform, defect-free, high strength.
2. Unique glaze layer:The appearance of a crucible has multi-special glaze layer, coupled with the molding material compact, greatly improving the corrosion resistance of the product, extending the life of the crucible.
3. Good oxidation resistance：Formulations designed to fully consider the use of the process to prevent oxidation of the graphite.
4. Resistance to chemical attack:Advanced materials and glaze recipes, effectively resist chemical attack
5. Excellent thermal shock resistance:The choice of material thermal expansion coefficient is small, fast heat conduction, high strength after isostatic pressing.
6. Resistance to high temperature：Crucible temperature range 400 - 1600 ℃.
7. Long life:Graphite crucible life than ordinary length of 2 - 5 times.
8. High thermal conductivity：Using natural graphite materials and isostatic pressing, the production of crucible wall is thin, fast heat conduction.
9. Significant energy saving：High thermal conductivity material crucible for the user in the course of a large number of energy savings.

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.
