I don't know how to use it oftenGraphite crucibleHave you noticed some problems in detail, that is, the graphite crucible is prone to transverse cracks sometimes. What is the cause? Xiaobian found three reasons:

1. Place the graphite crucible on the slag or the unsuitable crucible base. When taking out the crucible, if the position of the graphite crucible clamp is too high and the force is too large, cracks will appear on the surface of the crucible when the crucible clamp is not lowered.

2. It is caused by the impact of hard objects, such as throwing the casting material into the crucible, or knocking the bottom with hard objects such as iron bars. In addition, the thermal expansion used will also cause such damage.

3. Graphite crucible is not installed correctly. When installing a new crucible, if the refractory soil is tightly pressed under the crucible nozzle, the stress point will be concentrated at the most part of the graphite crucible when the crucible is cooled and contracted during use, resulting in cracks.

For the above three reasons, I hope you must be careful when using graphite crucibles, so as not to causeGraphite crucibleThe service life of becomes shorter, mainly because we pay more attention to the use process.
