Изобретение относитс  к области ЛйтейноГо производства, а именно к составам смесей Дл  изготовлени  форм при производстве алюминиевого лить .The invention relates to the field of casting production, namely to mixtures for the manufacture of molds for the production of aluminum casting.

Алюминиевые сплавы такие, как АЛ-19, ВАЛ-10, АЛ-9 и другие склонны к образованию гор чих трещин и рыхлот.Aluminum alloys such as AL-19, VAL-10, AL-9 and others are prone to hot cracks and loose.

Известные формовочные смеси дл  изготовлени  форм и стержней в производстве алюминиевого лить  не обеспечивают хороuiero качества отливок.The known molding compounds for the manufacture of molds and cores in the production of aluminum casting do not provide good quality castings.

Целью изобретени   вл етс  разработка такой рецептуры смеси дл  разовых форм, котора  могла бы обеспечить высокое качество поверхности без микронадрывов, плен, ужимин и других дефектов и предупредить образование гор чих трещин.The aim of the invention is to develop such a mixture formulation for one-off forms, which could provide high surface quality without micro-tears, captivity, cold wax and other defects and prevent the formation of hot cracks.

Дл  этого в состав формовочной смеси на основе кварцевого полужирного песка и мазута введен электрокорунд при следующем соотношении компонентов, вес. %: Кварцевый песок,For this purpose, electrocorundum was introduced into the molding sand mixture based on quartz bold sand and fuel oil in the following ratio of components, weight. %: Quartz sand,

За счет этого удаетс  достигнуть равномерного охлаждени  отливки, а тем; самымDue to this, it is possible to achieve uniform cooling of the casting, and thus; the most

Оптимальное содержание воды в смеси 0,5%, в противном случае понижаетс  ее пластичность .The optimum water content in the mixture is 0.5%, otherwise its plasticity decreases.

Свойства предлагаемой смеси наход тс  в пределах технических требований к формовочным смес м дл  алюминиевого лить .The properties of the proposed mixture are within the technical requirements for molding mixtures for aluminum casting.

В форме из предлагаемой смеси создаютс  услови  дл  ускоренного и равномерного охлаждени  жидкого мета.тла, скорость охлаждени  жидкого металла в такой форме приближаетс  к скорости охлаждени  жидкого металла в кокиле.In the form of the proposed mixture, conditions are created for accelerated and uniform cooling of the liquid meth. The cooling rate of the liquid metal in this form approaches the cooling rate of the liquid metal in the chill mold.
