Abstract

The invention relates to a device for measuring the quality change of the fireproof material in the high temperature and different atmosphere, which comprises a vacuum furnace and a quality measuring system, wherein the measuring system comprises a quality sensor connected with the fire resistant basket which is fitted in the vacuum, the lower of the quality sensor is connected with the heatproof thread, the lower of the thread is connected with the binding rod, the fire resistant basket is connected with the binding rod and a fire resistant bank is set on the basket. Said invention can measure the relations of the quality and temperature in the heating up process or in a certain temperature, and the measuring range is from normal temperature to 1700 deg, the measuring atmosphere maybe oxidation, reduction,neutral atmosphere and inert atmosphere, the quality range is 20-5000g, the distinguishability is 0.1-100mg.

Description

Technical field: [0001] The invention belongs to a tester, and in particular relates to a high-temperature thermogravimetric analyzer for a large sample refractory material for testing the quality change of a refractory material sample under high temperature and different atmospheres. Background technique: [0002] The quality change of refractory materials under high temperature and different atmospheres will directly affect its production and application. Measuring the relationship of refractory material quality with temperature and time is an important research method to study the high temperature physical and chemical properties of refractory materials. However, because refractories are multi-phase and heterogeneous materials, they usually contain a large amount of aggregates and pores. In the experiment, the mass of the sample is too small to truly represent the performance of the refractory. The measurement by the micro-thermogravimeter is usually used at present The range ...
