Product Description
Magnesium Slag Rock Wool Electric Furnace 2500kVA
Magnesium reduction slag is rich in calcium silicate and is chemically close to the melt used for mineral wool, which makes it a practical substitute for basalt in insulation wool production. This 2500kVA electric melting furnace is configured specifically for that route: magnesium slag, together with a small amount of conditioners, is melted into a uniform magma and then discharged to a centrifugal fiberising unit to make rock wool boards, blankets and pipes.
Advantages of the Electric Melting Route
- Clean heat source: no fuel combustion in the melting zone, so sulphur dioxide, nitrogen oxide and dust from the furnace are far lower than in a cupola.
- Stable magma quality: temperature is held within plus or minus 10 C, keeping viscosity constant, which is the key condition for a fine, uniform fibre.
- Flexible raw material ratio: magnesium slag can be blended with basalt, dolomite or blast furnace slag to reach the required acidity modulus.
- Energy efficiency: the closed furnace body with external insulation cuts heat loss, giving 15%-20% better energy utilisation than a conventional fuel fired melter.
- Waste to product: each ton of magnesium slag that is melted replaces mined basalt, and the finished wool locks the material into a durable insulation product.
Process Flow
- Magnesium slag is dried to below 1% moisture and screened to remove coarse inclusions.
- Slag, basalt and conditioner are weighed and mixed in the batching station, then fed through a sealed automatic charging system.
- The electric furnace melts the blend at 1450-1550 C; the closed furnace holds the pool at constant temperature.
- Magma flows through the forehearth and is fiberised by the four wheel centrifugal spinner, then collected in the wool chamber.
- Wool is needled, cut and packed into boards, blankets or pipe sections; off gas passes through the dust removal train.
