The offer purpose – increase in technical and economic indicators of work
steel - smelting furnaces due to increase in firmness of lining thanks to application
As magnesian gumboil we suggest to use pelitomorphic
(cryptocrystalline) magnesite the size of crystals of which does not exceed 5 - 7 microns.
On chemical and grain composition gumboil meets the requirements submitted
in table 3.
