Изобретение относитс к литейному производству , в частности к составам дл изготовлени многоразоБЫ.к прессованных литейных форм.The invention relates to foundry, in particular, to compositions for the manufacture of multirazburnyh pressed extrusion molds.
Известны составы формовочных масс на основе графита со св зующим - фосфатом алюмини . Однако такие составы не обеспечивают достаточной прочности получаемых форм. При сушке наблюдаетс коробление форм.The compositions of graphite-based molding compounds with a binder, aluminum phosphate, are known. However, such compositions do not provide sufficient strength of the obtained forms. When drying, warping is observed.
Цель предлагаемого изобретени - повышение прочностных, теплофизических и технологических свойств изготовл емых форм.The purpose of the invention is to increase the strength, thermal and technological properties of the forms produced.
Дл этого в состав формовочной массы введен корунд при следуюш,ем процентном соотношении компонентов, вес. %:To do this, corundum was introduced into the molding composition with the following percentage of components, weight. %:
Графит молотыйосноваGround graphite base

Однозамеш,енный фосфат алюмини 13-15Odnozamesh wen aluminum phosphate 13-15
В качестве исходного сырь дл приготовлени предложенного состава могут быть использованы отходы электродного производства и остатки графитовых электродов электродуговых печей. В качестве огнеупорного наполнител использован графит молотый фракции 0,06-3 мм. Корунд (шлифпорошок) фракции 0,03 мм марки ЭБ-50 выполн ет роль и наполнител ,и стабилизатора.As a raw material for the preparation of the proposed composition, electrode production wastes and residues of graphite electrodes of electric arc furnaces can be used. As the refractory filler used graphite milled fraction of 0.06-3 mm. Corundum (grinding powder) of the 0.03 mm fraction EB-50 performs the role of both a filler and a stabilizer.
Стабилизатор (корунд) при высоких температурах образует со св зуюш,им - однозамеш ,енным фосфатом алюмини -третичный фос фат, имеюш,ий температуру плавлени пор дка 2000°С и обеспечиваюш,ий формам, получаемым из предлол енного состава, высокие огнеупорность и механические свойства и многоразовую заливку сплавами на основе железа .At high temperatures, the stabilizer (corundum) forms with bonded, one-mixed, aluminum phosphate-tertiary phosphate, having a melting point of about 2000 ° C and providing forms obtained from the predlozhenny composition, high refractoriness and mechanical properties and reusable potting with iron-based alloys.
Отливки, получаемые в этих фор.мах, обладают высокой степенью точности чистотой поверхности .Castings produced in these shapes have a high degree of accuracy of surface finish.
