Application Scenarios

 

With high refractoriness and erosion resistance, it is suitable for core thermal equipment in steel mills:

  •  Electric Arc Furnace (EAF)：Protects the furnace lining, withstands the scouring of high-temperature molten steel, ensures stable smelting, and reduces the frequency of furnace lining replacement.

  •  Basic Oxygen Furnace (BOF)：As a key material for the BOF lining, it resists erosion from slag and molten steel, helps increase production efficiency, and adapts to BOFs of different tonnages.

  • Ladle Refining Furnace (LRF)：Strengthens the furnace lining in the refining process, optimizes molten steel composition, improves steel quality, and supports special steel production.

 

Service Support

 

  • Customized Production：Customizing the composition and performance parameters of magnesia-carbon bricks based on steel mill furnace types, steel grades, and other conditions to precisely match requirements.

  • Full-process Quality Control：Quality inspection throughout the process from raw materials to finished products, providing sample verification before production to ensure zero risk in operation.

  •  After-sales Collaboration：Regular follow-ups on usage conditions, assisting in optimizing furnace lining maintenance plans to extend equipment life.

  • Cooperation Expansion：Exploring supporting refractory material cooperation (such as monolithic refractories) based on trust. For details, please consult the business team.

 

From Market Entry to Reputation Cultivation：CMMC has built a value foundation for magnesia-carbon brick applications in steel mills with "customization + full-chain services", continuously empowering high-temperature smelting scenarios from responsive market entry to deep reputation cultivation.
