DESCRIPTION
The production of silicomanganese involves smelting manganese ore, quartz, and iron ore in a blast furnace or electric arc furnace. The process typically involves the following steps:
- Preparation of raw materials: Manganese ore, quartz, and iron ore are crushed and screened to obtain the appropriate size and shape for processing.
- Furnace charging: The raw materials are then charged into the furnace in the appropriate proportions, along with coke and flux.
- Smelting: The furnace is heated to a high temperature, and the raw materials are smelted to produce silicomanganese.
- Refining: The molten silicomanganese is then refined to remove impurities such as sulfur, phosphorus, and carbon.
- Casting: The refined silicomanganese is cast into different forms, such as lumps, powder, or briquettes, depending on the desired end use.
- Cooling and handling: The cast product is then cooled and handled as required.
