How does ferrosilicon melt?

Traditional ferrosilicon smelting adopts submerged arc furnace, which mixes silicon dioxide, steel chips and coke to form ferrosilicon. The ferrosilicon slag produced by this process still contains certain ferrosilicon components, and ferrosilicon slag and residual ferrosilicon powder need to be remelted in a ferrosilicon smelting furnace according to a certain proportion, and 60-80% ferrosilicon blocks can be obtained.

Ferrosilicon smelting furnace is based on the principle of electromagnetic induction, using the residual 10-25% metal component in ferrosilicon to assist smelting. After smelting, slagging and adding a certain proportion of alloying elements, qualified ferrosilicon will be obtained. Haishan Electromechanical Bianxiao Company arranges the parameters of ferrosilicon smelting furnace as follows for your reference.

I. Technical parameters of ferrosilicon smelting furnace:

1, ferrosilicon melting furnace uses: melting silicon slag and silicon powder.

2. Capacity of ferrosilicon smelting furnace: the capacity measured by steel is 1 ton.

3. Melting power of ferrosilicon smelting furnace: 800Kw

4. Ferrosilicon smelting furnace with transformer: 1000KVA.

5. Incoming voltage of ferrosilicon smelting furnace: 380V V V.

6. Ferrosilicon melting furnace? DC voltage: 500 volts

7. Melting frequency of ferrosilicon smelting furnace: 1000Hz.

8. Tilting mode of ferrosilicon smelting furnace: hydraulic tilting.

9. Working mode of ferrosilicon smelting furnace: continuous smelting.

Second, matters needing attention in smelting silicon slag in ferrosilicon smelting furnace

1, ferrosilicon melting furnace? When adding silicon slag in the initial stage, it should be added in small pieces. The size should be controlled at about 20 mm

2. When silicon slag melts in the furnace hearth of ferrosilicon smelting furnace, the power can be increased and silicon slag can be added.

3. Each ferrosilicon smelting furnace? After pouring, 30% silicon liquid should be reserved in the furnace, which can shorten the melting time.

4. The lining material of ferrosilicon smelting furnace is mainly acid lining material.

5. After the furnace of ferrosilicon smelting furnace is completely melted, it is usually allowed to stand for 3-5 minutes to regenerate slag.
