Изобретение относитс к литейному производству , а именно к составам формовочных смесей дл футеровки вагранок.This invention relates to a foundry, in particular to molding compounds for the lining of cupola furnaces.
Известны формовочные смеси дл литейного производства, содержащие в своем составе огнеупорный наполнитель, шамот, феррохромовый шлак, жидкое стекло, пенообразователь и воду.Known molding compounds for foundry, containing in its composition refractory filler, chamotte, ferrochromic slag, liquid glass, foaming agent and water.
Однако такие смеси имеют недостаточную прочность и термическую стойкость.However, such mixtures have insufficient strength and thermal resistance.
С целью повьишенИ прочности в состав предлагаемой формовочной смеси введен асбест и бентонит при следующем соотношении компонентов, вес. ч.: In order to improve strength, asbestos and bentonite are introduced into the composition of the proposed molding mixture in the following ratio of components, weight. including:
65-70 песок кварцевый 12-15 шамот порошкообразный 65-70 quartz sand 12-15 powdered chamotte
