Horizontal circulating heating furnace

Abstract

The invention discloses a horizontal circulating heating furnace, and relates to the related technical field of horizontal furnaces. The horizontal circulating heating furnace comprises a furnace body, a sample fixing device and a driving device, wherein, the furnace body is sequentially provided with a heating area, a cooling area and a control area which are arranged at intervals in the horizontal direction; the sample fixing device is provided with a first temperature sensor for monitoring the temperature of a to-be-detected sample; the driving device is arranged in the control area, is connected with the sample fixing device and drives the sample fixing device to circularly move between the heating area and the cooling area; when the temperature of the to-be-detected sample is lower than a threshold value, the driving device drives the sample fixing device to move to the heating area; and after the to-be-detected sample is subjected to heat preservation in the heating area at the preset temperature for preset time, the driving device drives the sample fixing device to move to the cooling area. According to the horizontal circulating heating furnace, the driving device is adopted to drive the sample fixing device to circularly move between the heating area and the cooling area so as to circularly heat and cool the to-be-detected sample, and the detection efficiency of the thermal shock performance of the to-be-detected sample is improved.

Description

technical field [0001] The present application relates to the technical field related to horizontal furnaces, in particular to a horizontal circulating heating furnace. Background technique [0002] During the research and development of high-temperature coating materials, it is necessary to test the high-temperature performance of the coating, for example, thermal shock performance. The detection methods of thermal shock performance include furnace cycle test, flame thermal shock test or laser thermal shock test. Among them, furnace cycle test is the most commonly used detection method, which mainly simulates the actual service environment of the coating, so that the coating can be heated and Cool to examine the failure of the coating. [0003] The common equipment for furnace cycle test is vertical heating furnace. The loading rod in the vertical heating furnace extends a predetermined length along the height direction of the furnace body, and the loading rod is welded w...

AI Technical Summary

Problems solved by technology

The loading rod in the vertical heating furnace extends a predetermined length along the height direction of the furnace body, and the loading rod is welded with a partition for carrying the sample to be tested. During the test, due to the influence of cyclic thermal shock and gravity of the sample to be tested The partition is prone to deformation or welding cracks, which will cause the sample to be tested to drop, ...
