DBM 95%+ MGO

China Mineral (Yingkou) Magnesia Co., Ltd.(CMMC) has been deeply engaged in the field of magnesia refractory materials. Relying on the high-quality magnesite resources in Dashiqiao, Liaoning, it has created multi-grade dead-burned magnesia (DBM) products through precise calcination and fine processing techniques. These products cover a series with MgO content ranging from 85% to 92%, 95%+, 97%+, etc., providing stable support for high-temperature industrial scenarios.

Core Advantages

 

As an enterprise with a complete industrial chain of magnesia materials, CMMC has built a closed-loop system covering "mines - production - quality control - application":

  • Controllable resources: Leveraging the core magnesite belt in Dashiqiao, it ensures the quality and supply stability of raw materials, and controls the accuracy of MgO content from the source.
  • Extreme high-temperature resistance: With a melting point of 2800℃, it maintains structural integrity even in ultra-high temperature environments up to 2400℃, providing "rigid protection" for ultra-high temperature kilns.
  • Excellent strength and toughness: Boasting a bulk density of ≥3.25g/cm³, it features outstanding compressive and wear-resistant properties, reducing the frequency and cost of equipment operation and maintenance.
  • Flexible customization: It supports customization of fine particle sizes such as 200 mesh and 325 mesh, meeting the deep processing needs of refractory mortar, high-end refractory bricks, etc.

Application Scenarios

 

DBM, with its "high refractories + strong stability", deeply covers core scenarios in high-temperature industries:

  • Refractory material manufacturing: As a basic raw material, it is used to produce alkaline refractory bricks, ramming mixes, furnace repair materials, and magnesia mortar, supporting the long-term service of linings in steel and cement kilns.
  • Iron and steel metallurgy: Added in EAF slag splashing protection and slag refining processes, it optimizes slag composition, extends furnace lining life, and improves scrap melting efficiency.
  • Special industries: In ultra-high temperature equipment such as glass kilns and non-ferrous metal smelting furnaces, it serves as coating materials and refractory aggregates to resist extreme temperatures and chemical erosion.

 

Service Support

 

CMMC empowers customers with "full-cycle value services":

  • Technical collaboration: Assigning refractory engineers to conduct direct engagement, offering services including raw material selection and formula optimization to address issues like cracking and erosion resistance in DBM applications;
  • Customized production: Tailoring DBM parameters such as particle size, purity and density based on customers' requirements for end products (e.g., high-end refractory bricks, special kiln linings);
  • Logistics and inventory: Leveraging the national warehousing network to achieve "batch delivery as per orders", collaborating with customers to build up safety stock and ensuring the continuous operation of production lines;
  • New customer support: For first-time cooperative clients, providing a package of "small-batch sampling + process guidance" to reduce introduction costs. For more details, please contact the business team.
