Description
Изобретение относитс к обмазкам , вл ющимс вспомогательными формовочными материалами, примен емыми нри литье.The invention relates to coatings that are auxiliary molding materials used in casting.
Известны обмазки, нримен емые Л/ш нокрыти форм, изготовл емых по выплавл емым модел м при точном литье, состо щие из тонкой фракции молотого или природного кварца, смешанного с гидролизованным этилсиликатом или жидким стеклом.The coatings applied to the L / shnokryti molds made by melted models in precision casting, consisting of a fine fraction of ground or natural quartz, mixed with hydrolyzed ethyl silicate or liquid glass are known.
Эти обмазки вл ютс кислыми и устойчивы при литье сталей, не способных разъедать и размывать кислую футеровку формы.These coatings are acidic and resistant when casting steels that are not capable of corroding and washing away the acidic lining of the mold.
Указанные обмазки имеют тот недостаток , что при заливке форм стал ми , взаимодействуюп.1,имн с кислой футеровкой, они способствуют разъеданию форм, что приведет к понижению качества поверхности отливок.These coatings have the disadvantage that when molds are poured, they interact, interact with Clauses 1, with acid lining, they contribute to corroding the molds, which will lead to a decrease in the surface quality of the castings.
Прех лагаема огнеупорна обмазка дл лмть форм, изготовл емыхPreh lagaema refractory coating for molds made
по выплавл емым модел м, состоит из двуокиси титана.on melted models, consists of titanium dioxide.
Техническую двуокись титана прокаливают при температуре 1150- 1200, размалывают и просеивают, а затем смещивают ее с гидролизированным этилсиликатом или жидким стеклом.Technical titanium dioxide is calcined at a temperature of 1150–1200, milled and sieved, and then displaced with hydrolyzed ethyl silicate or liquid glass.
Эта обмазка, вл сь основной, исключает разъедание и размывание форм стал ми, взаимодействующими с кислой футеровкой.This coating, which is the main one, eliminates the corroding and erosion of the molds, which interact with the acid lining.
