6.How to extend the service life of Medium Frequency melting furnace?
First of all, when the first use of medium frequency melting furnace, it is necessary to make a lining in medium frequency furnace and sinter it. Furnace lining is a protective layer to protect the induction coil using quartz sand and other materials along the induction furnace wall. Lining should be a molding, sintering should follow the low-power slow heating mode, more than 36 hours of continuous baking, so that it fully cured.
After medium frequency induction furnace lining good knot, how correct and reasonable operation is the key to extend the life of MF melting furnace . Under normal circumstances, before operating induction furnace should first check whether the water cooling system is smooth , whether cooling water pressure, water temperature is normal, whether there is water leakage, and whether the hydraulic system is working properly. When Operating, careful and don’t grope recklessly, one person operate, one person monitoring, and irrelevant personnel is strictly prohibited into the engine room to prevent electric shock. Smelting process must use the dry material, and do light discharge, dosing, when the materials are melted as required, promptly poured, to avoid the high temperature increase lining loss; multiple observation, when found the furnace outside has Red phenomenon, should shut down MF power promptly, poured out the melted metal and other measures to avoid the occurrence of accidental leakage. When using should also note that when found lining has become very thin, can not continue to use, you should smash the old lining to do a new lining, to prevent leakage accident occurred.
