Изобретение относится к литейному производству, а именно - к составам самотвердеющих смесей, используемых для изготовления литейных форм и стержней. Самотвердеющая смесь имеет в своем составе для улучшения прочностных свойств, живучести смеси и улучшения выбиваемости материал с дисперсностью 0,08 мм, обожженный при t = 110oС в течение 1 ч и содержит 93,5 - 96,5 оксида магния при следующем содержании ингредиентов в вес.%: материал, содержащий оксид магния 1,0 - 5,0, ортофосфорная кислота γ = 1,526 г/см2 4,0 - 6,0, щавелевая кислота 0,1 - 0,15, огнеупорный наполнитель - остальное.The invention relates to foundry, namely to the compositions of self-hardening mixtures used for the manufacture of foundry molds and cores. The self-hardening mixture incorporates a material with a dispersion of 0.08 mm, calcined at t = 110 o C for 1 hour to improve the strength properties, the vitality of the mixture and improve the knockability, and contains 93.5 - 96.5 magnesium oxide with the following ingredients in wt.%: material containing magnesium oxide 1.0 - 5.0, orthophosphoric acid γ = 1,526 g / cm 2 4.0 - 6.0, oxalic acid 0.1 - 0.15, refractory filler - the rest.
