Изобретение относитс к физико-механическим исследовани м, а именно к методам испытани керамических образцов форм, полу ценных по выплавл емым модел м при безопочной прокалке.The invention relates to physico-mechanical research, in particular to methods for testing ceramic sample forms, semi-valuable in melted models during flaskless calcination.
Известен способ физико-механических исследований , при котором образцы оболочек лить по выплавл емым модел м равномерно нагревают в специальных печах с электронагревом 11.There is a method of physico-mechanical research, in which shell samples are cast by melted models are uniformly heated in special electric-heated furnaces 11.
Этот способ не позвол ет приблизить услови испытаний образца к реальным услови м безопочной прокалки, когда внутренн и наружна поверхности керамической оболочки нагреваютс неравномерно.This method does not allow the test conditions of the sample to be closer to the real conditions of non-fired calcination, when the inner and outer surfaces of the ceramic shell are unevenly heated.
Известен также способ физико-механических исследований, в котором керамический образец при испытании нагревают в устройстве с тепловыми экранами, которые исключают лучевой нагрев части поверхности образца, обеспечива заданную неравномерность нагрева 2.There is also known a method of physico-mechanical research, in which a ceramic sample is heated in a device with heat shields when tested, which eliminates the radiation heating of a part of the sample surface, providing the specified heating non-uniformity 2.
Недостатком известного способа вл етс то, что при нагреве поверхностей испытываемого образца они наход тс в одинаковых услови х окружающей их атмосферы, что не соответствует реальным услови м безопочной прокатки керамических оболочек, когда внутренн поверхность керамических оболочек находитс в атмосфере измен ющихс по времени концентраций газов, а наружна поверхность находитс в услови х окружающего ее атмосферного воздуха или продуктов сгорани природного газа с коэффициентом избытка воздуха ,6, т.е. данный способ испытаний The disadvantage of the known method is that when the surfaces of the test sample are heated, they are under the same conditions in the surrounding atmosphere, which does not correspond to the real conditions of the non-flask rolling of the ceramic shells when the inner surface of the ceramic shells is in the atmosphere and the outer surface is under the conditions of the surrounding atmospheric air or products of combustion of natural gas with an excess air ratio of 6, i.e. this test method
10 не позвол ет создать те напр жени в образце , которые возникают в реальных услови х безопочной прокалки при разных скорост х испарени и удалени органических веществ из керамических оболочек в услови х разных 10 does not allow one to create the stresses in the sample that arise under real conditions of non-flask calcining at different rates of evaporation and removal of organic substances from the ceramic shells under conditions of different
IS концентраций и разных составов окружающих их газовых сред.IS concentrations and different compositions of the surrounding gaseous media.
Цель изобретени - повыщение качества и достоверности определени свойств за счет приближени условий нагрева образца к ре20 альным услови м безопочной прокалки литейной формы.The purpose of the invention is to increase the quality and reliability of the determination of properties by approximating the heating conditions of the sample to the real conditions of flaskless calcining of the casting mold.
