Description
Изобретение относитс к огнеупор ной промышленности/ к шихтам дл из готовлени огнеупорных изделий форс термитового состава. Т,акие издели могут примен тьс дл футеровки раз личных агрегатов черной и цветной металлургии, в цементной и керамической промышленности. Известна шихта l дл изготовле ни огнеупорных изделий, содержаща вес.%: Форстерит Магнезитовый клинкер Циркон Наиболее близкой к изобретению вл етс шихта 2 , содержаща , ве Дунит10-30 Бромистыйсерпентинит45-55 Магнезит. 20-40 Недостатком известных шихт вл етс невысока плотность и температура деформации под нагрузк изделий, полученных из этих шихт (1690°С. Цель изобретени г повышение плотности и высокотемпературной прочности изделий. Цель достигаетс введением в состав , содержащий хромистый магнезиально-силикатный материал и магнезит, вуокись циркони и использованием в качестве хромистого магнезиальносиликатного материала хвостов обогаени хромитовых руд при следующем соотношении компонентов, вес.%: Хвосты обогащени хромитовых руд70-88 Магнезит10-20 Двуокись циркони 2-10 Хвосты обогащени хромитовых руд имеютсостав, вес.%: 27,72-34,96 1,35-1 ,65 0,83-1,53 5-11,03 0,37-13,7 35,45-47,08 Фазовый состав огнеупорных изделий, полученных из предлагаемой шихти снаThe invention relates to the refractory industry / charge for the preparation of refractory products of force-termites. T, such products can be used for lining various aggregates of ferrous and nonferrous metallurgy, in the cement and ceramic industries. The known charge l for the manufacture of refractory products, containing wt.%: Forsterit Magnesite clinker Zircon Closest to the invention is charge 2, containing, Dunit 10-30 Methremite serpentine 45-55 Magnesite. 20-40 A disadvantage of the known charge is the low density and deformation temperature under load of the products obtained from these charges (1690 ° C. Object of the invention: an increase in the density and high-temperature strength of the products. The goal is achieved by introducing into the composition containing the chromium magnesia-silicate material and magnesite , zirconium oxide and using chromite magnesian silicate material as a chromium magnesially silicate material in the following ratio of components, wt.%: Magnesite chromite ores 70-88 enrichment tails -20 Zirconium dioxide 2-10 Tailings of chromite ores are composed, wt.%: 27.72-34.96 1.35-1, 65 0.83-1.53 5-11.03 0.37-13.7 35.45-47.08 The phase composition of refractory products obtained from the proposed sleep mix
