FMK Series

Rebonded Magnesia-Chrome Bricks (KROMAG FMK)

The FMK Series represents MRL’ flagship range of high-performance rebonded magnesia-chrome bricks, engineered to withstand the most demanding conditions in steel and non-ferrous metallurgy. Produced from high-purity fused magnesia-chrome aggregate and fired in ultra-high temperature tunnel kilns, FMK bricks possess a dense and stable microstructure that delivers outstanding slag resistance, thermal shock stability, and vacuum integrity. As the pioneer of mag-chrome brick manufacturing in China, MRL has over six decades of experience and holds multiple national patents in this product category. FMK bricks have been widely applied in RH degassers, VOD ladles, AOD converters, EAFs, BOFs, and ladles worldwide, as well as in non-ferrous furnaces such as flash smelters and Kaldo converters.

Application

  • Steelmaking: RH degassers, VOD refining ladles, AOD converters, electric arc furnaces (EAF), working lining of ladles, converter tap holes, slag lines, scouring zones, tuyere areas.
  • Non-ferrous & Metallurgy: Flash smelters, anode furnaces, non-ferrous converters, reverberatory furnaces, Kaldo furnaces in high-wear and high-corrosion zones.
  • Chemical & Other industries: Black liquor recovery boilers, gasifiers, and thermal treatment kilns exposed to severe thermal and chemical environments.

Steel, Non-Ferrous, Gasification

Description

  • Strong resistance to basic slag and high-temperature steel erosion
  • Excellent oxidation-reduction stability and thermal shock performance
  • High integrity under vacuum conditions with low spalling risk
  • Optional salt-impregnated grades for lower porosity and longer service life
  • Ideal for working linings, slag lines, tuyere zones, and high-wear areas
