Description

Известен способ производства абразивных изделий па керамических св зках, включающий формование, сушку и последуюидий обжиг .A known method for the production of abrasive products on ceramic bonds, including molding, drying and subsequent burning.

Одиако при использовании известного способа невозможно нолучить издели  высокого качества, так как при относптельно ннзкнх температурах в присутствии восстановнтсл,ной среды илн восстановител  (декстрина, вход щего в состав массы) кремнезем диссоциирует с образованием окиси кремии  SiO, котора  поражает издели  вкраплени ми в виде так называемой коричневой «мушки.While using a known method, it is impossible to obtain high-quality products, since at relatively low temperatures in the presence of a reducing medium or reducing agent (dextrin, which is part of the mass), silica dissociates to form SiO, which affects the products in the form of called brown "flies.

Цель изобретени  состоит в улучшении чистоты иоверхиости изделий и уменьшении брака и достигаетс  тем, что обжиг осуществл ют в восстаиовительной среде при более высокой, чем в известной технологии, температуре пор дка 1000-1235С с последующей изотермической выдержкой в окислительной среде при температуре 1200-1240°С в течение 1,5-2,0 час, что позвол ет практнчески полностью избавитьс  от вкраплений окиси кремни .The purpose of the invention is to improve the purity of the product and reduce the scrap, and is achieved by firing in a reducing medium at a higher temperature than 1000-1235 ° C than in the known technology, followed by isothermal aging in an oxidizing environment at a temperature of 1200-1240 ° C. C for 1.5-2.0 hours, which virtually eliminates silicon oxide inclusions.

Способ пронзводства абразивных изделий на керамическнх св зках, включающий формование , сушку и последующпй обжиг, отличаюгцийс  тем, что, с пелью улучгиенн  чнстоты поверхности изделий и уменьшени  брака, обжиг осуществл ют в восстановнтельной среде при температуре 1000-1235 С с последующеи пзотермнческой выдерлчкой в окислительной среде прн температуре 1200-1240С в течение 1,5-2,0 час.The method of producing abrasive products on ceramic bonds, including molding, drying and subsequent firing, is different from the fact that, with a better improvement of the surface of the products and reduction of scrap, the firing is carried out in a reconditioning medium at a temperature of 1000-1235 ° C with a subsequent extraction temperature of the oxide, and the oxide is in the oxide layer, and the oxide is in the oxide layer, and the oxide is in the oxide layer, and the oxide is in the oxide layer, and the oxide is in the oxide layer, and the oxide is removed, and the oxide is in the oxide layer and the oxide is in the oxide layer, and the oxide is in the oxide layer. Wednesday prn temperature 1200-1240S for 1.5-2.0 hours.
