How to add materials when smelting ferrosilicon?

[2024-02-06 14:16:58]

1. Each batch of materials must be mixed evenly before being added to the furnace. No random addition is allowed. As we all know, the proportion of each batch of materials is calculated based on the chemical reaction principle of ferrosilicon smelting and the composition of the raw materials used, ... Read More

Ferrosilicon smelting operations: segregation and pulverization

[2024-02-06 14:16:26]

The temperature of the molten iron coming out of the furnace is usually 300 to 350°C higher than the melting point of ferrosilicon, so the molten iron condenses slowly. During the slow condensation process, pure silicon with a small density floats up, and the dense iron silicide sinks, that is, ... Read More

Ferrosilicon smelting operations: finishing and warehousing

[2024-02-06 14:15:46]

Finishing must be carried out in strict accordance with national standards. Ferrosilicon should be delivered in blocks. The supplier can use lime powder or graphite slurry as the ingot mold coating. The thickness of the coating attached to the ferrosilicon product shall not exceed 1 mm. There must ... Read More

Ferrosilicon smelting operations: power supply and charge

[2024-02-06 14:15:22]

Power supply in front of furnace Ferrosilicon is generally produced in a submerged arc furnace using a continuous operation method. The current input from the transformer enters the furnace filled with charge through the electrode. During the entire smelting process, the electrode is always deeply ... Read More

The important role of silicon in casting

[2024-02-06 14:14:20]

Liquid cast iron contains silicon, which reduces the solubility of carbon. The higher the silicon content in the molten iron and the lower the carbon content, the more carbon will be squeezed out. silicon ferro It is not difficult to understand from the iron-carbon phase diagram: when the molten ...

Main physical and chemical properties of silicon

[2024-02-06 14:13:23]

Physical properties of silicon Silicon is the second element in the fourth main group of the periodic table. Pure silicon is a dark gray opaque crystalline substance with metallic luster. It is hard and brittle and is a good semiconductor material. The main physical properties of silicon are as ... Read More

Ferrosilicon: Why can’t we add additional materials?

[2024-02-06 14:07:59]

1. When too much silica charge is added, the electrode may be inserted too deep in the initial stage. If the time is too long, it will cause a lack of carbon around the electrode, the crucible will shrink, the electrode will easily lift up, the material surface will have poor air permeability and ...
