Silicon Chip Briquetting Press

What are the disadvantages of recycling metal scrap directly?

1. Iron filings are small in volume and high in density. Directly put into the furnace for smelting will block the rising channel of the furnace air and directly affect the melting effect.

2. When the airflow in the furnace is large, the iron filings will be blown away, resulting in a low discharge rate.

3. Iron filings can be easily attached to the furnace wall without briquette treatment, making the furnace wall thicker and corrosive to the furnace.

4. Scrap iron, silicon, manganese, and other materials are not easy to store. Their contact with water and air will cause oxidative deterioration. However, the melting point of iron oxide is higher than that of iron, which results in a long melting time and an increase in combustion cost

5. Iron chips are easy to be wrapped by slag, resulting in the low utilization rate of raw materials.
