Abstract

FIELD: foundry. SUBSTANCE: blend contains as a binder carbamide-furane resin with formaldehyde content up to 1.0%. Reduced concentration of binder improves environmental condition and lowers cost of blend. Low nitrogen content (up to 9.0%) reduces gas release in the casting process and improves quality of cast product. Blend may be used for machining hot-box cores and molds. EFFECT: improved quality of blend in various respects.

Изобретение относится к литейному производству и позволяет использовать в качестве смеси для изготовления стержней и форм в нагреваемой оснастке смесь со связующим ФИРАР-12Л. ФИРАР-12Л-карбамидно-фурановая смола с содержанием формальдегида до 1,0%. Смеси на основе смолы ФИРАР-12Л содержат меньше связующего, чем смеси на основе смолы КФ 90 или смолы КАФУР, вследствие чего улучшаются санитарно-гигиеническое условия и снижается себестоимость смеси. Низкое содержание азота в смоле (до 9,0%) снижает газовыделение при формировании отливок и улучшает качество литья. Смеси могут быть использованы при изготовлении стержней и форм машинным способом.The invention relates to foundry and allows you to use a mixture with a binder FIRAR-12L as a mixture for the manufacture of rods and molds in a heated snap. FIRAR-12L-carbamide-furan resin with a formaldehyde content of up to 1.0%. FIRAR-12L resin-based mixtures contain less binder than KF 90 or KAFUR resin-based mixtures, which improves sanitary conditions and reduces the cost of the mixture. The low nitrogen content in the resin (up to 9.0%) reduces gas evolution during casting and improves casting quality. Mixtures can be used in the manufacture of rods and molds by machine.
