Hot Slag Conditioning Furnace Equipment Introduction & Technical Parameters
1. Equipment Overview
The hot slag conditioning furnace is core thermal equipment for metallurgical solid waste resource utilization. It receives hot molten slag at about 1300℃ discharged from submerged arc furnaces and blast furnaces. Through electric arc heating, component conditioning and homogenization treatment, it stabilizes molten slag temperature at 1450–1500℃, accurately adjusts chemical composition and flow rate. The treated slag can be directly supplied for rock wool fiber forming and building material raw materials, realizing hot slag direct utilization, waste heat recovery and zero discharge of solid waste.
Core Functions
Slag receiving & storage: Closed slag feeding to reduce heat loss and dust emission
Temperature rising: Three-phase electric arc heating to compensate temperature drop of 100–150℃
Component conditioning: Add quartz sand, limestone and other additives with max conditioning ratio ≤30% to adjust acidity coefficient to optimal fiber-forming range
Temperature & composition homogenization: Combined electric arc stirring and bottom nitrogen injection, temperature uniformity ±5℃
Quantitative slag tapping: Water-cooled slag outlet for stable flow control matching centrifuge production
Waste heat recovery: Flue gas waste heat utilization rate ≥80% for preheating and power generation
