By adding various non-oxide additives as per requirement and being conjunted with binding agent, MgO-C Brick is produced from materials of magnesium oxide with high melting point up to 2800 ℃ and graphite stuff characteristic of high melting point and difficult to be infiltrated by furnace slag. As a special refractory composite, MgO-C Brick effectively makes use of the strong anti-corrosion ability from magnesite clinker and the high thermal conductivity & low expansion from graphite, and thus improves magnesite clinke of low resistance ot spalling.



Application Field


MgO-C Bricks are widely used in following fields:

  • Convertor furnace for steel making;
  • Water cooled EAF furnace;
  • Bottom, wall and slag line of steel ladles;
  • Lining of BOF.

A safety data sheet (SDS), material safety data sheet (MSDS), or product safety data sheet (PSDS) is an important component of product stewardship, occupational safety and health, and spill-handling procedures. SDS formats can vary from source to source within a country depending on national requirements.

SDSs are a widely used system for cataloging information on chemicals, chemical compounds, and chemical mixtures. SDS information may include instructions for the safe use and potential hazards associated with a particular material or product. The SDS should be available for reference in the area where the chemicals are being stored or in use.

Our team is in dedicate and professional position to provide above information for our customers and related operators to properly deal with what we supply to all over the world. You are welcome to contact us to get such information or data, and please click MSDS or just address
