Product Description
Gasification Slag Rock Wool Electric Furnace Overview
The gasification slag rock wool electric melting furnace is a submerged arc melting furnace specially developed for the resource utilization of coal gasification slag, a bulk solid waste from coal chemical and synthetic ammonia plants. The furnace melts pretreated gasification slag together with flux additives at 1450-1550°C and continuously delivers a homogeneous melt to the fiber spinning line, producing high-quality rock wool (mineral wool) insulation fibers from gasification solid waste, achieving both waste reduction and high-value recycling.
Core Features
- Bulk Solid Waste Utilization: Each furnace line consumes large quantities of gasification coarse slag and fine slag, greatly reducing slag yard occupation and landfill cost for coal chemical plants.
- Stable Melt Quality: Submerged arc heating with continuous charging keeps the molten bath temperature uniform, guaranteeing stable melt viscosity and surface tension for smooth high-speed fiber spinning.
- Residual Carbon Adaptability: The furnace design handles the residual carbon in gasification slag with controlled oxidation and melt homogenization, preventing foaming and ensuring consistent fiber quality.
- Energy Efficient Melting: Optimized electrode layout and heat insulation reduce melting energy consumption, while waste heat from flue gas can be recovered for drying or preheating.
- Environmental Protection: Closed-loop water cooling, fume collection and baghouse dedusting control dust and gas emissions, meeting industrial environmental standards for solid waste treatment plants.

Production Process
Gasification slag is dewatered, dried and blended with flux additives to adjust the acidity coefficient for fiber forming. The prepared charge is continuously fed into the electric melting furnace and melted at 1450-1550°C into a homogeneous liquid. The melt flows through the taphole to a high-speed centrifugal spinner, where it is attenuated into rock wool fibers, collected and formed into insulation boards, felt and pipe sections.
Application Fields
- Rock wool insulation boards, felt and pipe sections for building and industrial insulation;
- Coal gasification slag comprehensive utilization projects in coal chemical bases;
- Thermal insulation raw material production lines for steel, power and chemical plants.
