Description
При термической переработке с;ганцев в туннельных печах при конденсации отход щих газов нолучаетс сланцева смола, KOTOpyFo предлагаетс примен ть в качестве крепител дл стержневых смесей как самосто тельно, так и в сочетании с другими крепител ми. Удельный вес туннельной смолы, пригодной дл литейных целей, должен быть в пределах 1,0-1,03, а в зкость но Энглеру должна быть в пределах от 4 до 8 при 75° и от 15 до 25 при 50°.During thermal processing of Cahnians in tunnel kilns, shale tar is obtained during condensation of off-gases, KOTOpyFo is proposed to be used as a binder for core mixes both independently and in combination with other binder. The specific gravity of a tunnel resin suitable for casting purposes should be in the range 1.0-1.03, and the viscosity but Engler should be in the range from 4 to 8 at 75 ° and from 15 to 25 at 50 °.
Результаты лабораторн-ых и заводских испытаний показывают, что сланцева туннельна смола вл етс высококачественным крепителем дл стержневых мтсс и может c;iyжить полноценным заменителем масл ных крепителей. Стержни, изгг)товлеиные на этой с.моле, (обладают высокой прочностью и соверигенно не пригорают к отливкам.The results of laboratory and factory tests show that shale tunnel resin is a high quality fastener for core materials and can be a full-fledged substitute for oil binder.
