Description

Применение формовочных смесей с гипсоМ Сокрапдает период сзшки и обжига форм, включа  ,п охлаждение , с 72 час. до 8 час. дл  крупных фор.м- и до 3-4 час. дл  мелких форм. Сушка производитс  сразу же при максимально возможной Б сушильной печи температуре (750-800). Такой режим сушки, не вызыва  образовани  трещин, сообш;ает форме высокую пористость , а следовательно, и газопроницаемость , исключа  этим необходимость применени  в формовочнойThe use of molding compounds with gypsum. Reduces the period of szshka and roasting forms, including, n cooling, from 72 hours. till 8 o'clock for large forms. and up to 3-4 hours. for small forms. Drying is performed immediately with the highest possible drying oven temperature (750-800). This mode of drying, without causing the formation of cracks, gives the form a high porosity and, therefore, gas permeability, thus eliminating the need to use in the molding

Формы, изготовл емые из указанных формовочных смесей, увлажненные равным по объему количеством воды, не требуют армировани  железом и допускают сушку сразу же при температуре 750-800°.Molds made from the above molding mixtures, moistened with an equal volume of water, do not require iron reinforcement and allow drying immediately at a temperature of 750-800 °.

Указанные формовочные смеси обеспечивают получение чугунного лить  с чистой поверхностью, лишенной пригара и облоев, и могут быть применены во всех случа х сложных отливок при единичном или мелко-серийном производстве.These molding mixtures provide iron casting with a clean surface, devoid of burns and areas, and can be applied in all cases of complex castings in single or small-scale production.
