SEMI-recombined magnesite-chrome brick
Description:
The semi-recombined magnesite-chrome brick refers to a magnesite-chrome brick made of artificially synthesized fused magnesite-chrome sand and chrome concentrate and magnesite as a fine powder. In the domestic, the magnesite-chrome bricks are made of granules, the co-sintered materials are fine powders or chrome concentrate powder and magnesite powder are mixed as fine powder. In order to distinguish, the magnesite-chrome brick made of electro-melt as the granule and the co-sintered magnesite chrome as the fine powder can be called the pulverized co-sintered magnesite-chrome brick.
Advantages:
High purity, low porosity, high temperature strength, good volume stability, good thermal shock resistance
Application:
Furnace refining device, RH furnace vacuum chamber, VOD slag line; heavy ferrous metallurgical converter tuyere zone, flash furnace reaction tower, sedimentation tank, anode slag line, lean electric furnace slag line and slag outlet
