(1) ,Intermediate frequency furnace onset of melting due to inductance and capacitance on the line have been slow to properly match the current instability, it can only supply low power in a short time. Once the current is stable, it should be converted to full load power. Capacitors should be continually adjusted during the melting process to maintain a high power factor in the electrical equipment. After the furnace material is fully melted, the molten steel is superheated to a certain extent, and then the input power is reduced according to the smelting requirements.

 

(2) should control the appropriate melting time, the gas melting time is too short, it will cause difficulties in voltage and capacitor selection, too long will increase the unhelpful heat loss.

 

(3) furnace feed charge containing inappropriate or excessive rust occurs "bridging" phenomenon, it should be addressed promptly. "Bridge" makes the upper unmelted material not fall into the molten steel, so that the melting is stagnant, and the overheating of the bottom molten steel easily damages the lining, and the molten steel absorbs a large amount of gas.

 

(4) since the electromagnetic stirring, molten steel central ridge, slag flows often bond to the edge of the crucible furnace wall, so during melting furnace conditions to be continuously supplemented in accordance with slag.
