When applying the new tong pot, pay attention to the excellent inspection of the quality of the new graphite crucible, and do an excellent heat treatment before application to prevent the graphite crucible from being damaged. When the temperature of the graphite crucible is raised, it is also necessary to strictly control the temperature raising rate of the graphite crucible.

Graphite crucible has excellent thermal conductivity and heat resistance. In the whole process of high temperature application, the linear expansion coefficient is small, and it has certain resistance to rapid heating and chilling. It has strong corrosion resistance to acid and partial alkali aqueous solutions, and has high-quality organic chemistry reliability. In the metallurgical industry, forging, mechanical equipment, chemical plants and other industrial sectors, it is commonly used as a smelter for alloy structural steel and for smelting rare metals and aluminum alloys, and has a good practical effect on safety engineering.

1. In the whole process of raising the temperature of the graphite crucible, when the temperature is below 400 degrees, it is also necessary to slow down the rate of raising the temperature of the graphite crucible and gradually increase the temperature;

2. When heating the graphite crucible, the temperature increase rate of the graphite crucible should be as slow as possible to prevent the graphite crucible from being damaged due to sudden temperature increase;

3. When the temperature exceeds 600 degrees, people can speed up the temperature increase rate of the graphite crucible, so that the graphite crucible can quickly exceed the production and processing temperature.
