Magnesia-chromite and chromite-magnesite refractory materials

摘要

refractories magnezjowo - chromitowe and chromitowo - magnezjowe shock resistant heat in the form of dried and smoked are characterised by the fact that the masses for their manufacture in addition to chrome ore and adhesives shall koklinkier magnezjowo - ferrytowy containing 3u00f714% masow s magnezjoferrytu mgfe2o4 and koklinkier magnezjowo - spinelowy,in which the ratio of the sum of the weight mass cr2o3 al2o3 and fe2o3 is within the range 0,8u00f71,8, whereby the ratio of the mass koklinkieru magnezjowo - ferrite to participate koklinkieru magnezjowo - spinelowego range from 0.5 to 2.0, and molecular. the two types koklinkieru00f3w in weight is not less than 30% and not more than 95 mass%.
