Description

Изобретение касаетс  приборов дл  измерени  деформации образцов огнеупорных (например, керамических) материалов, вызываемой нагрузкой, прилагаемой к испытываемому образцу в ус.чови х нагрева его до высоких температур в криптоловой электропечи.The invention relates to instruments for measuring the deformation of samples of refractory (e.g., ceramic) materials caused by the load applied to the test sample when it is heated to high temperatures in a cryptol electric furnace.

Известные приборы подобного рода с применением вертикальных опорных стержней из огнеупорного материала (например, графита) дл  креплени  на них измерительного устройства обладает тем недостатком , что нагружающа  система в них обычно св зана кинематически с силоизмерительной частью прибора, что отражаетс  на точности показаний прибора.Known devices of this kind using vertical support rods made of refractory material (for example, graphite) for attaching a measuring device to them have the disadvantage that the loading system in them is usually kinematically connected with the force-measuring part of the device, which is reflected in the accuracy of the instrument readings.

В описываемом приборе этот недостаток устранен тем, в качестве груза, осуществл ющего сжатие испытываемого образца, применены съемные грузовые цилиндры из огнеупорного материала, свободно надеваемые на опорный стержень и отделенные от него воздушной прослойкой (зазором).In the described device, this disadvantage is eliminated by the fact that as a cargo that compresses the test specimen, removable cargo cylinders of refractory material are used that are freely attached to the support rod and separated from it by an air gap (gap).

Такое устройство прибора, при котором нагружающа  система кинематически не св зана с силоизмерительной частью, повышает точность показаний прибора и расшир ет область его применени .Such a device device, in which the loading system is not kinematically connected with the force-measuring part, improves the accuracy of the instrument readings and expands its field of application.

На схематическом чертеже изображен описываемый прибор н общеы виде.The schematic drawing shows the described device in general form.

Прибор состоит из вертикальной электрической крпптоловой печи /, во внутренней полости которой помещают на нодставке нз огнеупорного материала испытываемый образец 2. На верхнем торце печи установлена на микрометрических винтах стойка 3 дл  кренлеии  измерительного устройства, например, индикатор 4 и вертикального керамического полого стержн  5, верхний торец которого соприкасаетс  с опорным щтифтом индикатора. Нижним своим торцом керамический стержень через диск 6 установлен на иснытываемый образец.The device consists of a vertical electric furnace and /, in the inner cavity of which a test sample 2 is placed on the base of the refractory material. At the upper end of the furnace, a stand 3 for inclining the measuring device, for example, indicator 4 and a vertical ceramic hollow rod 5, is mounted on the microscrew screws. the end of which is in contact with the bearing pin of the indicator. The bottom of its ceramic rod through the disk 6 is installed on the sample under test.
