5T / 3500kw intermediate frequency furnace

5T / 3500kw intermediate frequency furnace

Working mode of intermediate frequency furnace:

1.1 One set of furnace body is smelted for production, and the other set of furnace body is spared. The power is set to 3500kw, and the melting time (5T molten iron to 1550°C) ≤55 minutes/furnace

1.2 a smelting furnace, a furnace insulation (refining), melting power of 3200kw thermal power ≤ . 3 00KW / furnaces. In this state, the melting time ( . 5 T iron water to. 1 . 5 . 5 0 deg.] C) ≤ 60 minutes.

1.3 The two furnace bodies are smelted and produced at the same time.
