Description

Известные химико-твердеющие формовочные смеси дл  чугунного, стального и бронзового лить , содержащие мелкий кварцевой песок, водный раствор едкого натри  и жидкое стекло, под воздействием температуры залитого металла превращаютс  в прочн ю спекшуюс  массу, почти не поддающуюс  разрушению при выбивке общеизвестными средствами . Поэтому особую трудность представл ет удаление стержней изKnown chemical hardening molding mixtures for cast iron, steel and bronze casting, containing fine quartz sand, an aqueous solution of sodium hydroxide and water glass, under the influence of the temperature of the poured metal, turn into a strong sintered mass that is almost indestructible when being knocked out by well known means. Therefore, the removal of rods from

ОТЛИВОК.CASTING

В предлагаемой химико-твердеющей смеси этот недостаток устранен тем, что в смесь ввод т отходы содового производства в количестве 3-5%. При этом могут быть использованы отходы Слав нского содового комбината и других подобных предпри тий. Состав отходов содового производства, дл  введени  в химико-твердеющие смеси с. едующий (з весовых процентах):In the proposed chemical hardening mixture, this disadvantage is eliminated by the fact that soda production wastes are introduced into the mixture in an amount of 3-5%. At the same time, waste from the Slavsky soda plant and other similar enterprises can be used. The composition of the waste soda production, for introduction into the chemical hardening mixtures c. eats (by weight percent):

Эти отходы ДОЛЖНЫ содержать определенное количество хлористого кальци , количества осталадых составл ющих могут колебатьс .This waste MUST contain a certain amount of calcium chloride, the amounts of remaining constituents vary.

Под действием температуры металла эти отходы начинают разлагатьс  приблизительно при 300°, а при 900° разложение заканчиваетс . Разложение отходов нарушает монолитность смеси, преп тству  ее спеканиюПредмет изобретени Under the action of metal temperature, this waste begins to decompose at approximately 300 °, and at 900 ° decomposition ends. The decomposition of the waste violates the solidity of the mixture, preventing its sintering.
