Product Description
DC Rock Wool Furnace (DC Mineral Wool Furnace) Introduction
This equipment is a DC-powered high-temperature electric melting furnace for rock wool/mineral wool production, which serves as the core equipment in rock wool manufacturing. It is especially suitable for the resource utilization of industrial waste residues (such as hot slag from silicomanganese submerged arc furnaces).
1. Core Positioning and Application
The DC rock wool furnace is a DC-powered high-temperature electric melting furnace mainly used in rock wool/mineral wool production to heat and melt raw materials like basalt and slag, which are then centrifugally blown into fibers. The equipment in your image is specifically designed for the resource utilization of industrial waste residues:
- It receives 1200-1300℃ hot slag from silicomanganese submerged arc furnaces, heats and conditions it to 1400-1500℃, and directly supplies it to centrifuges for mineral wool production.
- It is suitable for 30,000-ton/year mineral wool production lines and is the key equipment for solid waste recycling.
2. Core Advantages of DC Power Supply
Compared with traditional AC furnaces, DC power supply technology brings significant performance improvements and cost advantages:
| Performance Aspect | Advantages of DC Rock Wool Furnace |
|---|---|
| Energy Consumption Cost | Power consumption per ton of product is reduced by 10~15%, and coke/auxiliary fuel consumption is reduced by 10% |
| Production Efficiency | Output is increased by about 20% at the same power, with more uniform and stable bath temperature |
| Electrode Consumption | Electrode consumption is saved by about 35%, significantly reducing consumable costs |
| Product Quality | Built-in electromagnetic stirring and electrolysis functions result in more uniform melt composition, higher fiber purity, and higher yield |
| Grid Friendliness | No harmonic interference to the power grid, eliminating the need for additional complex filtering equipment |
3. Equipment Structure Analysis (Based on Your Image)
- Lower Yellow Furnace Body: The main melting bath of the DC furnace, responsible for receiving hot slag/raw materials and heating them to a molten state via electrode discharge.
- Upper Operation Platform: Equipped with electrode lifting mechanisms and flue gas collection pipes, facilitating maintenance and parameter adjustment by operators.
- Right Discharge/Launder: Continuously transports the conditioned high-temperature melt to the centrifuge, serving as the key channel connecting the melting furnace to the fiber forming process.
- Safety Protection: Yellow safety guardrails and ladders comply with the safety operation and maintenance specifications for industrial equipment.
4. Application Scenarios and Value
- Solid Waste Recycling: Directly uses hot waste residues from ferroalloy and steel industries to produce mineral wool, turning waste into treasure and reducing solid waste emissions.
- Green and Energy-Saving Production: Significantly reduces energy consumption and carbon emissions compared with traditional processes, adapting to green production requirements under the "dual carbon" goal.
- Cost-Effective Rock Wool Production: With the advantages of low cost, high efficiency, and high quality, it is the mainstream direction for upgrading and transforming the rock wool industry at present.
