The fire-proof material used in the cement profession>>>
Ordinary magnesium chromium
brick and half direct coupling magnesium chromium brick
Ordinary magnesium
chromium brick characteristic：Namely silicate union magnesium chromium
brick, Fires from the 70's in our country aqueous method cement kiln takes to
bring with the use, Because its craft is simple, the cost is low,until now still
was the middle and small scale cement rotary kiln fires the belt the main kiln
liner material.Half direct
coupling magnesium chromium brick characteristic：Is in the ordinary magnesium chromium brick
production craft foundation,Joins the chemical additive the synthesis craft to
make. The product has the resistance to fouling, anti- flaking and hangs the
kiln skin performance good characteristic. Is suitable in violates the law the
cement kiln below 12, the vertical Pohl kiln and the aqueous method kiln fires
the belt use,Is the ordinary magnesite chrome brick ideal substitute.
