Descripción del producto

It has good thermal conductivity and high temperature resistance. In the process of high temperature use, the coefficient of thermal expansion is small, and it has strain resistance to rapid heat and cold. It has strong corrosion resistance to acids and alkaline solutions, and has chemical stability.
-Instructions for the use of graphite crucible products
1. The specification number of the crucible is the capacity of copper (#/kg)
2. The graphite crucible should be kept away from moisture and placed in a dry place or on a wooden rack when storing it.
3. Handle with care when transporting, and it is strictly forbidden to drop and shake.
4. Before use, it needs to be baked in the drying equipment or furnace, and the temperature is gradually increased to **0.
5. The crucible should be placed below the surface of the furnace mouth to prevent the furnace cover from wearing the upper mouth of the crucible.
6. Feeding should be based on the melting amount of the crucible, not too much feed, too tight to avoid expanding the crucible.
7. Furnace tools and crucible clamps should conform to the shape of the crucible, and clamp the middle part to avoid damage to the crucible by local stress.
8. When removing molten slag and coke on the inner and outer walls of the crucible, tap it to avoid damage to the crucible.
9. A proper distance should be kept between the crucible and the furnace wall, and the crucible should be placed in the middle of the furnace.
*0. Excessive use of combustion aids and additives will reduce the service life of the crucible.
*1. During use, rotate the crucible once a week to extend the service life of the crucible.
*2. Avoid direct spraying of strong oxidizing flame on the side and bottom mound of the crucible.
