Product Introduction
I. Tapping Hole Opener
Function: Automatically opens the taphole during iron tapping, replacing manual drilling. Suitable for 300-5800m³ blast furnaces, increasing tapping efficiency by 60%.
Core Parameters:
Drilling diameter: 120-180mm (adaptable to taphole depth of different furnace capacities)
Feed rate: 0.5-1.2m/min, maximum drilling depth 8m
Power type: Hydraulic drive (system pressure 16-25MPa)
Technical Advantages:
Automatic positioning: Laser aiming + PLC control, taphole deviation ≤50mm
Wear-resistant parts: Drill bit uses cemented carbide, lifespan ≥50 times/set
II. Clay Gun
Function: After tapping, clay is injected into the taphole for sealing to prevent gas leakage. Clay injection pressure 30-45MPa (meets the needs of high-pressure blast furnaces).
Structure Type:
Type | Applicable Scenarios | Clay Injection Amount | Features |
Electric Clay Gun | Small and medium-sized blast furnaces (≤1000m³) | 50-100kg/time | Easy maintenance, low cost |
Hydraulic Clay Gun | Large blast furnaces (≥2000m³) | 100-200kg/time | Stable pressure, high degree of automation |
Key Configurations:
Nozzle: High-alumina silicon carbide material, resistant to 1500℃ molten iron erosion
Clay cylinder volume: 0.3-2.0m³, clay conveying accuracy ±2%
III. Slag Damper
Function: Blocks the slag taphole to discharge liquid slag, controlling slag-iron separation. Suitable for blast furnaces with daily iron production of 500-10000t.
Technical Features:
Movement method: Rotary/mobile, slag blocking time ≤30s
Sealing structure: Water-cooled copper plug + spring clamping, leakage rate ≤1%
Drive method: Pneumatic/hydraulic (working pressure 0.6-1.0MPa)
IV. Blast Furnace Gas Waste Heat Power Generation Unit (TRT)
Function: Utilizes blast furnace gas waste heat for power generation, power generation per ton of iron 30-50kWh (accounting for 8-12% of blast furnace process energy consumption), investment recovery period 3-5 years.
System Composition:
Turbine: Axial flow/radial flow, inlet pressure 0.15-0.3MPa
Generator: Power 500-30000kW, power generation efficiency ≥85%
Control system: DCS automatic adjustment, grid voltage 10-35kV
Environmental Value:
No additional energy consumption, annual CO₂ reduction 20,000-100,000 tons (calculated based on a 3000m³ blast furnace)
V. Slag granulation Equipment (GGBS)
Function: Grinds blast furnace slag to a specific surface area of 400-500m²/kg for use in cement admixture production, increasing the added value of slag per ton by 50-80 yuan.
Process Route:
Slag → Jaw crusher → Ball mill/Vertical mill → Classifier → Finished product (particle size ≤45μm, ≥85%)
Equipment Configuration:
Grinding host: Vertical mill (processing capacity 30-150t/h), power consumption ≤40kWh/t
Dust collection system: Bag filter, emission concentration ≤30mg/m³
Equipment Selection
Efficiency improvement: Tapping hole opener + clay gun linkage control, tapping cycle shortened to 15-20 minutes
Energy-saving benefits: TRT + GGBS combination, comprehensive cost reduction of 20-30 yuan per ton of iron
Service guarantee: Provides equipment linkage debugging, refractory material consumption optimization scheme, warranty period 1 year (excluding wearing parts)
