Product Description

Blast furnace slag granulation insulation device


Equipment use:
This equipment is used to receive hot melt slag from blast furnace, after heat preservation, air quenching and granulation after release.


Equipment overview and structure:
This equipment is designed and manufactured according to GBl0067.1-4 <Basic Technical Conditions for Electric Heating Equipment>.
1. Stove casing.
2. Refractory.
3. Modular stove cover.
4. Electrode lifting device and copper tube type conductive cross arm.
The electrode lifting device has the following advantages:
· The conductive transverse arm is flexible in lifting, the system has small inertia and good rigidity;
· Simplified structure, good insulation performance and high reliability;
· Can easily and reliably clamp and relax the electrode;
· The electrode clamping force is large, and the clamping head is not easy to spark;
· The electrode lock is a water-cooled component, which will not cause the electrode to slide due to thermal expansion in the high temperature area.
5. Short-net system.
6. Hydraulic system.
7. Cooling water system.
8. Furnace body hole opener.
9. Slag inlet device.
The slag inlet device is mainly composed of a copper water-cooled chute and a sliding device is provided at the bottom. After the work is finished, the slag can be moved outside the oven to clean the residue, which can effectively reduce the workload and extend the service life of the chute.
10. Electrical equipment and control systems.
11. Hydraulic oil pump control.
12. Electrode lifting regulator system.


Key Technical Highlights: Blast Furnace Slag Granulation Insulation Equipment
  • Rapid Quenching Granulation System: Adopts high-pressure water jet or air-cooled atomization technology to achieve <0.5-second rapid solidification of molten slag (1450-1550℃), forming glassy granules with 90%+ uniformity (particle size 0.1-5mm) and minimal crystalization.
  • Intelligent Thermal Insulation Module: Integrates multi-layer refractory materials + vacuum insulation panels, maintaining post-granulation slag temperature at 600-800℃ with <5% heat loss/hour, enabling direct heat recovery (up to 3.2 GJ/ton slag) via built-in heat exchangers.
  • Closed-Loop Dust Control: Equipped with negative-pressure cyclone dust collectors and wet scrubbers, achieving <30mg/m³ particulate emissions—far below industrial standards—while recycling 99% of water used in granulation for cyclic reuse.
  • Adaptive Process Control: PLC-based system dynamically adjusts water/air flow, insulation intensity, and conveyor speed based on real-time slag composition (CaO/SiO₂ ratio) and discharge volume, ensuring stable granule quality across varying blast furnace operating conditions.


Core Features & Benefits

  • Efficient Granulation: Adopts advanced atomization/granulation technology to quickly solidify molten blast furnace slag into uniform, small granular slag with stable properties.
  • Insulation & Energy Retention: Equipped with professional insulation systems to maintain slag temperature during processing, facilitating subsequent resource recycling (e.g., heat recovery, building material production).
  • Environmental & Economic Value: Reduces slag waste and dust emissions, turning industrial by-products into reusable materials while cutting energy consumption.
