What crucible is used for melting copper in medium frequency induction melting furnace
Crucible is a container for melting and refining metal liquid, as well as solid-liquid heating and reaction.The main types of crucibles are as follows:
2.Cast iron crucible
7.Silicon carbide crucible
Graphite crucible is used for melting copper in intermediate frequency induction melting furnace. Because copper is non-magnetic metal, it is necessary to heat the crucible with electric circuit, and then the heat of crucible can melt copper metal. Select the appropriate size of crucible and put it in the middle of furnace ring. The gap is one finger and many points. Then, a layer of heat insulation cloth is wrapped inside the coil, and the filler is filled between the heat insulation cloth and the crucible, and the sharp object is used to strike To be honest, it’s a tedious thing to tell the truth. If it’s not true, there will be sequelae. As for fillers, mullite sand, quartz sand and so on can be used.
