Refractory Crucible

Refractory Crucible production materials can be summarized into three types. One is crystalline natural graphite, the other is plastic refractory clay, and the third is calcined hard kaolin type skeleton clinker.
Refractory Crucible models and specifications are more, in the application of production scale, batch size and smelting material varieties are not limited, can be arbitrarily selected, applicability is strong, and can ensure the purity of the smelting material.
1. Place it in a dry place after use, avoid rainwater invasion; Bake slowly to 500 degrees Celsius before use.
2. Should be according to the capacity feeding, avoid squeezing too tight, so as not to crack the refractory crucible metal thermal expansion.
3. Take out the metal melt, it is best to use a spoon to scoop out, as far as possible with calipers, calipers and other tools should be consistent with the shape, to avoid local force is too large and shorten the service life.
4. Crucible service life is related to usage, should avoid strong oxidation flame directly sprayed to the refractory crucible
