Blast Furnace Molten Slag Holding Furnace Equipment Introduction

The blast furnace molten slag holding furnace is core metallurgical equipment for waste heat recovery and resource utilization of blast furnace molten slag. It receives, keeps warm and stably outputs high-temperature liquid blast furnace slag at 1400–1500℃, providing qualified high-temperature slag materials for rock wool production, slag-iron recovery, building material processing and other industries, featuring energy saving, environmental protection and cost reduction.

1. Core Functions

  • Constant Temperature Holding: Stably maintain molten slag temperature at 1430–1470℃ to meet follow-up process requirements.
  • Composition Homogenization: Eliminate temperature and component fluctuation to ensure stable slag quality.
  • Continuous Feeding: Realize intermittent slag feeding and continuous slag discharging to match continuous production lines.
  • Slag-Iron Separation: Equipped with iron tapping hole to separate residual iron and improve slag purity.
  • Waste Heat Utilization: Reduce heat loss and secondary heating energy consumption.

2. Equipment Structure (Mainly Vertical Cylindrical Type)

2.1 Steel Furnace Body

  • Furnace shell: Welded steel plate cylinder with high rigidity and good sealing performance.
  • Water jacket: Circulating cooling water jacket installed on furnace wall for structural protection.

2.2 Composite Refractory Lining

  • Thermal insulation layer: Lightweight castable for heat insulation.
  • Transition layer: High-alumina refractory material with excellent thermal shock resistance.
  • Working layer: Carbon brick and ramming mass, high temperature resistance and slag corrosion resistance.
  • Furnace bottom: Thickened refractory structure for load bearing and anti-permeation.

2.3 Main Openings

  • Slag inlet: Upper furnace body for pouring molten slag.
  • Slag outlet: Lower part for uniform discharge of liquid slag.
  • Iron discharging hole: Discharge settled residual iron regularly.
  • Electrode hole: Install graphite electrodes for auxiliary heating.

2.4 Heating & Temperature Control System

  • Heating mode: Graphite electrode electric heating or self-heat preservation.
  • Rated power: 2000–4000KVA.
  • Intelligent temperature control: PLC closed-loop control, temperature accuracy ±10℃.

2.5 Auxiliary Systems

  • Slag level monitoring: Real-time liquid level detection.
  • Circulating cooling system: Complete water pressure and flow protection device.
  • Dust removal system: Collect flue gas and dust to meet environmental discharge standards.

3. Working Principle & Process

  1. High-temperature molten slag from blast furnace is poured into the holding furnace.
  2. Constant temperature maintenance and composition homogenization inside the furnace.
  3. Residual iron settles at furnace bottom for separation.
  4. Homogenized high-temperature liquid slag is continuously discharged for downstream production.
  5. Efficient heat preservation retains slag waste heat to save production energy consumption.


4. Core Advantages

  • High energy-saving efficiency, greatly reduce power consumption per ton slag.
  • Stable slag temperature and composition, improve finished product qualification rate.
  • Low emission and low carbon, conform to green metallurgy development trend.
  • Long service life of furnace lining, low operation and maintenance cost.

5. Application Fields

  • Rock wool and thermal insulation material production
  • Slag iron recycling and metal recovery
  • High-quality raw materials for new building materials

6. Main Technical Parameters (Standard 4000KVA Model)

  • Rated Capacity: 4000KVA
  • Working Temperature: 1400–1500℃
  • Hourly Processing Capacity: 8–12t/h
  • Temperature Control Precision: ±10℃
  • Structural Form: Vertical cylindrical water-cooled furnace
