Silicon manganese hot slag insulation furnace for solid waste treatment equipment

The silicon manganese hot slag insulation furnace is an equipment used for insulation treatment of hot slag in the production process of silicon manganese alloy:

Role:
Maintain temperature: The temperature of the hot slag generated in the production of silicon manganese alloy is usually around 1300 ℃. The insulation furnace can maintain the hot slag at a suitable temperature range of 1300-1450 ℃, meeting the requirements of subsequent production processes. For example, when used in the production of slag cotton, it can keep the hot slag in good flowability and facilitate processing.
Promoting quenching and tempering reaction: When using silicon manganese hot slag to produce mineral wool and other products, it is necessary to add quenching and tempering agents for quenching and tempering treatment. The stable high-temperature environment provided by the insulation furnace helps to promote the thorough mixing and reaction between the tempering agent and the hot slag, enabling the slag to achieve appropriate composition, viscosity, and other indicators, and improving product quality.

Structural characteristics
Furnace body: Generally made of steel plate shell to provide structural support and protection. There are multiple layers of furnace lining inside, usually including asbestos board layer, ramming material layer, and carbon brick layer from outside to inside. Asbestos board layer can effectively reduce heat loss; The pounding material layer can enhance the structural strength of the furnace lining; The carbon brick layer is resistant to high temperature, acid and alkali corrosion, and can withstand the high temperature and erosion of hot slag.
Heating system: Some insulation furnaces use electrode heating method, where electrodes are inserted into the furnace and heat is generated through resistors using current to heat and maintain the temperature of the hot slag, ensuring uniform and stable temperature inside the furnace. Some may also use other methods such as gas heating.
Flow control device: Flow control holes will be installed at the bottom or side of the insulation furnace, and flow control valves will be equipped, such as through insert plates to control the opening of the holes, so as to accurately control the outflow and flow rate of hot slag to meet the requirements of subsequent production processes.

Working principle
The thermal insulation furnace for silicon manganese hot slag mainly relies on the insulation performance of the furnace lining to reduce heat loss to the outside, while compensating for heat loss through the heating system to maintain the temperature of the hot slag inside the furnace. When the hot slag generated during the production process of silicon manganese alloy is poured into the insulation furnace, the heating system starts working to maintain the temperature inside the furnace within the set range. When it is necessary to discharge the hot slag for subsequent processing, the opening of the flow hole is adjusted by the flow control device to allow the hot slag to flow out of the insulation furnace at an appropriate flow rate and velocity. For insulation furnaces using electrode heating, after the electrodes are energized, the current generates heat in the resistive medium inside the furnace (such as hot slag and some conductive materials inside the furnace), which is evenly distributed inside the furnace, effectively heating and insulating the hot slag.
