Wear resistant castable for slag runner and granulation system

Description

Slag runner and granulation system are essential process equipment in blast furnace slag treatment systems. However, they operate under extremely harsh conditions with multiple failure mechanisms:

 

  1. Acidic solution corrosion
  2. High-speed water flow carrying abrasive particulate matter
  3. Potential explosions caused by incomplete iron-slag separation
  4. Frequent thermal shock cycles

 

Under these combined destructive mechanisms, conventional wear-resistant lining materials typically last only 1-2 years, far below user requirements. To address this, we have developed a specialized ceramic reinforced wear-resistant castable specifically engineered for slag runner and granulation system.

 

Key Features

 

  • High strength and exceptional wear resistance
  • Superior erosion/abrasion resistance
  • Excellent acid and alkali corrosion resistance
  • Outstanding thermal shock resistance
  • Organic binder-free formulation for better aging resistance and environmental safety
  • Suitable for slag trough linings, granulation tower wear layers in blast furnaces, EAFs, and submerged arc furnaces
  • Can also be applied in various hopper environments

 

Application Methods

 

  • Precast Components – Ideal for tight schedules or existing trough renovations. Our prefabricated ceramic wear-resistant trough segments enable fast on-site installation.
  • Cast-in-place Pumping – Recommended for new construction projects, providing superior integrity.
  • Wet Spray Application – For large-area applications like hoppers, offering 90% of cast-in-place wear resistance with higher efficiency.
  • Trowel Application – For localized repairs and special applications.

 

Technical Advantages

 

  1. Wear-resistant linings for slag runner and granulation system in blast furnaces of all sizes
  2. Wear-resistant layers for submerged arc furnaces and EAFs
  3. Protective linings for various material hoppers and storage yards
  4. Suitable for both complete system installation and localized repairs
