Induction melting operation steps and common fault analysis

 Induction melting operation steps and common fault analysis

Induction smelting step useful check single crystal furnace, try single crystal furnace before formal jobs, single crystal furnace, melting product sampling inspection, adjustment test, the use of single crystal furnace power security, after the completion of these steps can be omitted.
Should be reviewed by induction melting equipment, see if there are any obvious damaged parts, and then according to the requirements of specification to the trial operation, if after trial work is normal, you can begin to formal production, but also constantly in the process of production of check products, to see if some of the products, product quality is qualified, if the index is not up to standard, will adjust the machine quality is unqualified, until melting product quality up to par.
Common single crystal furnace fault are crystal rods, single crystal furnace crystal rod shaking machine can still functioning, but the production efficiency is low, induction smelting products quality is poor so in order to improve the efficiency of the induction melting and quality, not blind smelting, must inspect the single crystal furnace. Crystal rods should inspect lift shaking head, cooling system and vacuum system. If it is lift head appear problem, is under maintenance, changed institutions or rotating mechanism. If it is cooling system and vacuum system appear problem, need to adjust the silicon material and structure of a heavy hammer. There is no problem if you examine these places, see if the inert gas such as argon flow inside the furnace, argon gas flow in the furnace, requires a modified single crystal furnace, the evenness of single crystal furnace thermal field distribution.
