Description

Согласно изобретению предлагаетс  способ получени  из огнеупорных материалов (смесей) литейных форм многократного действи  дл  цветного лить  с применением дл  схватывани  вместо обжига силикатные крепители на основе щелочных гидросиликатов, с последующей сущкой при 150°.According to the invention, a method is provided for the preparation of multi-effect casting molds from refractory materials (mixtures) for non-ferrous castings, using silicate based on alkaline hydrosilicates for setting instead of firing, followed by substance at 150 °.

Применение таких крепителей обеспечивает достаточную механическую прочность и термостойкость форм, что позвол ет отливку изделий в эти формы производить многократно.The use of such fasteners provides sufficient mechanical strength and heat resistance of the molds, which allows casting the products into these molds to be performed many times.

Рекомендуютс  следующие составы дл  приготовлени  литейных форм в %:The following formulations are recommended for the preparation of casting molds in%:
