Graphite Crucible Melting Gold with Spout

Graphite crucible melting gold with spout- is involved in high temperature applications. Made of high-quality graphite material, durable and reliable in performance.

Gold melting graphite crucible with nozzle is widely used in precious metal smelting and jewelry industry. Also widely used in the dental industry. .

In addition to the various industries mentioned above, these crucibles are also used in laboratories conducting high-temperature testing, chemical manufacturing research, and new material development. Because they can withstand high temperatures, they are ideal for analyzing materials and developing new material applications.

In summary, Graphite crucible melting gold with spout- are essential for industries that rely on high temperature applications. So, if you are looking for a reliable crucible for your melting needs, the Gold Melting Graphite Crucible is the perfect choice for you.

Crucible heat transfer is slow
1. Failure to preheat and bake the sweet pot according to standard procedures;
2. Slag accumulation adheres to the inner wall of the crucible;
3. The crucible has reached the end of its service life

Oxidation too fast
1. Irregular operation during hoisting or moving results in damage to the glaze layer;
2. In the resistance furnace, there is no corresponding resistance wire or band on the top or bottom of the crucible;
3. In a gas furnace, the mouth of the crucible has no flame to block oxygen and is directly exposed to the air;
4. In a gas furnace, the flame directly impacts the bottom of the crucible;
5. The working temperature is too high.

Cracked in the middle or bottom
1. When the base is not in use:
2. The crucible is poorly installed and should be placed smoothly in the middle of the furnace body and kept level with the base;
3. There is slag accumulation or residual molten metal inside the crucible;
4. The metal material is added too full, or the metal ingot is placed horizontally or diagonally in the crucible;
5. Man-made damage during operation;
6. There is a temperature difference in the furnace body.

The crucible exploded
1. The graphite crucible material does not contain any substances that can cause explosions, so the explosion of the crucible is basically caused by the material becoming damp or heating up too quickly;
2. The graphite crucible has become damp and the temperature rises too fast during heating;
3. The metal materials added during the work are not completely dry;
4. The temperature rises too fast during preheating.

Crucible corrosion
1. Add flux when the crucible is empty or the metal is not completely melted;
2. Excessive use of flux;
3. Some fluxes are highly corrosive;
4. The fuel used contains corrosive substances;
5. Long-term abnormal high-temperature operation will cause melting of the crucible glaze layer similar to corrosion.

Oral rupture
1. There is too thick slag accumulation at the mouth of the crucible, or there is slag accumulation in the gap between the mouth and the furnace cover ring;
2. The mouth of the crucible is oxidized too quickly;
3. The feeding material hits the mouth multiple times;
4. The mouth is in contact with metals with large heat transfer coefficients such as iron.
