High Iron Sentered Magnesite

"People compound MgO 85i 87i sintered Magnesite with steel and Phosphor to produce Gunning material and call it as High Iron Magnesite. Both of the sintered function and the effect of use are not good due to the mixture of magnesite and iron is not uniformity. Later, someone (Martin)mixed Magnesite powder and iron Phosphor according to a scale, the performance was obviously improved. This kind of sand is call Martin Sand later. Our High Iron Magnesite is Martin Sand indeed, it is different from the traditional sand, HMF68A improve the content of CaO, it remain as 2CaO.Fe.O39(C2F) in the sand, Fe.O3 in C2F melt into periclase under the high temperature, this help to improve the crystal position in Magne - site c/s, it is easy to sinter and good for use, It is super material for moden furnace, LD rotary furnace liner and bottom.
