Refractory material slag resistance test device

Abstract

The invention provides a refractory material slag resistance test device, which mainly comprises a reaction gas cylinder, a gas valve, a gas purification device, a heating furnace, a crucible, slag, a refractory material sample, a sample rotating suspender, a photoelectric rotating device, a tail gas processing device, a lifting mechanism, a temperature control thermocouple, a temperature measurement thermocouple, a computer control system and the like. In the test process, the refractory material sample is made by a certain size and fixed on a disc type test tray, the slag is put in the crucible, the crucible is placed in a heath, a computer is started to run a temperature raising program, a protective gas is introduced, the refractory material sample is placed in the slag by the lifting device after the slag is completely melted, the rotating device is started, the computer controls the rotating speed of the rotating device, the refractory material sample is rotated in the slag to perform dynamic corrosion simulation, the rotating device is stopped at a preset time, the sample is taken out by the lifting device, and the corrosion condition of the sample is observed.

Description

technical field [0001] The invention relates to the field of test equipment. Specifically, it is an experimental device for quickly testing the performance of refractory materials against slag erosion. Background technique [0002] Refractories are necessary materials for various high-temperature equipment, and are widely used in metallurgy, cement, ceramics, glass and other industries. The erosion of refractory materials by slag is one of the main reasons for the damage of refractory materials. At present, the test equipment for the slag erosion resistance of refractory materials is not perfect. Generally, there are two commonly used ones: one is the use of intermediate frequency electric furnaces, and the other is Bottom rotary slag resistance test furnace. Among them, the former has problems such as a large amount of sample cutting and preparation, high assembly requirements, and a large amount of furnace building and dismantling, and cannot accurately control the tempe...
