Ramming Mass

Magnesia-based unshaped refractory materials, with high-purity magnesia as the core raw material, boast excellent refractoriness (up to 1700℃ and above), strong resistance to alkaline slag erosion, and good volume stability. They are key lining materials in high-temperature industrial fields such as metallurgy, building materials, and chemical industry.

CMMC manufactures a full range of magnesia-based unshaped refractory materials, including castables, gunning mixes, ramming mixes, plastic refractories and repair materials, which are suitable for various construction scenarios.Among them, magnesia-based ramming mixes have high density and good plasticity, making them suitable for irregular parts such as converters and ladles. Their key indicators can be customized to ensure structural stability at high temperatures.

Core Advantages

 

  • Comprehensive product system: Covering a full range of magnesia-based unshaped refractory materials such as magnesia castables, gunning mixes, and ramming mixes, which can be adapted to different construction scenarios and usage requirements.
  • Accurate customization capability: Capable of customized production according to the specific physical and chemical indicators provided by customers (such as compressive strength, flexural strength, re-firing linear change rate, bulk density, etc.). For magnesia ramming mixes, gunning mixes and other products, with mature indicator systems and product schemes already in place, parameters can be flexibly adjusted.
  • Strict quality control: Every step from raw material selection to finished product inspection is strictly controlled to ensure that products meet the required indicators.
  • Complete supporting services: In addition to providing customized products, a supporting technical team is available to offer working condition analysis, parameter optimization suggestions, and construction guidance.
