Description

Коэффициент линейной усадки новых снлавов в прессформе-0,2- 0,3%, жидкотекучесть-в несколько дес тков раз выше жидкотекучести обычных модельных композиций.The coefficient of linear shrinkage of new films in the mold — 0.2–0.3%, fluidity — is several tens of times higher than the fluidity of conventional model compositions.

При выплавлении моделей при те: 1пературе 150-180° модельные сплавы, пронизыва  мнкропоры керамической облицовки форм, в 4-5 раз повышают прочность керамикиDuring the melting of models with those: 1 temperature of 150-180 °, model alloys, penetrating the multi-pores of the ceramic lining of the forms, increase the strength of ceramics by 4-5 times

(прочность керамики на разрыв более 60 кг/см). После прокаливани  керамической оболочки, наход щейс  в кварцевом песке, в форме создаетс  восстаповительна  атмосфера , улучшающа  поверхность отливок .(ceramics tensile strength of more than 60 kg / cm). After calcining the ceramic shell, which is in quartz sand, a regenerating atmosphere is created in the mold, which improves the surface of the castings.

По проверенным практическим: данным общий технологический цикл лить  сокращаетс  до б-8 раз по сравнению с обычным циклом лить  с применением других модельных материалов и форм с жидкими наполнител ми . Весь возврат модельных сплавов и сухих наполнителей (кварцевого песка) при новом методе лить  используетс  в оборот. Точность отливок повышаетс  до 3 класса против 5-7 класса точности при использовании парафипостеариновых моделей.According to proven practical data, the total casting process cycle is reduced to b-8 times as compared to a conventional casting cycle using other model materials and forms with liquid fillers. The entire return of model alloys and dry fillers (silica sand) with the new casting method is used per turn. The accuracy of castings is increased to grade 3 versus grade 5-7 when using paraphipostearic models.

Теплостойкость новых модельных сплавов примерно в 2 раза выше теплостойкости модельных масс парафин-стеарин, прочность-в 4- 5 раз (прочность на изгиб достигает 60 кг/см), температура каплепадени -более 70°, разм гчени - не ниже 60°, плавлени -не вьппе 95.The heat resistance of new model alloys is about 2 times higher than the heat resistance of model paraffin-stearin masses, strength is 4-5 times (bending strength reaches 60 kg / cm), dropping temperature is more than 70 °, softening is not less than 60 °, melting - not 95
