Изобретение относитс к составу шихты дл изготовлени огнеупорных изделий, налример набивиых тиглей индукционных печей.BACKGROUND OF THE INVENTION The invention relates to the composition of a mixture for the manufacture of refractory products, nalimer stuffed in crucibles of induction furnaces.
Известна шихта дл изготовлени огнеупорных изделий, включающа електроплавленную окись магни и добавку.A known charge for the manufacture of refractory products, including electroplating magnesium oxide and an additive.
Целью изобретени вл етс повышение термической стойкости и уменьшение усадки изделий.The aim of the invention is to increase thermal stability and reduce shrinkage of products.
Поставленна цель достигаетс тем, что шихта содержит в качестве добавки циркон при следующем соотношении компонентов, вес. %:The goal is achieved by the fact that the mixture contains zircon as an additive in the following ratio of components, weight. %:

Образцы, изготовленные из данной шихты, увлажненной 5-7% по весу раствором сульфитно-спиртовой барды плотностью 1,22 г/см и спрессованные три удельном давлении 1000 кг/см, имеют усадку после обжига 0,5%, кажущуюс плотность 3,0-3,1 г/см.Samples made from this mixture, moistened with 5-7% by weight solution of sulphite-alcohol bards with a density of 1.22 g / cm and pressed three specific pressure of 1000 kg / cm, have a shrinkage after firing 0.5%, apparent density 3.0 - 3.1 g / cm.
термостойкость 20 теплосмен (1400-20°С. воздух).heat resistance is 20 thermal cycles (1400–20 ° C. air).
Повышенна термостойкость обусловлена наличием в обожженном материале трехфазной структуры периклаз-форстерит-бадделеит. Форстерит располагаетс между зернами периклаза в виде тонких прослоек, внутри которых видны зерна бадделеита.The increased heat resistance is due to the presence of three-phase periclase-forsterite-baddeleite in the calcined material. Forsterite is located between the grains of periclase in the form of thin interlayers, inside which the grains of baddeleyite are visible.
