Non-magnetic high-temperature test device

Abstract

The invention discloses a non-magnetic high-temperature test device, which is characterized in that: a heating device is non-magnetic, and the temperature can be precisely controlled. The invention adopts the technical scheme that: the non-magnetic high-temperature test device comprises a hot-air generator and a working chamber, wherein the hot-air generator consists of a box body, a heating system and a temperature control system, the box body is provided with a temperature control instrument, a starting button, an air passage, an upper port and a lower port; the working chamber consists of an upper hot-air circulating passage, a lower-part hot-air circulating passage, a hot-air circulating transitional passage, a drying box, a hot-air circulating passage elbow or a steering pipe, the working chamber is fixed on a working platform through the upper-part and the lower-part hot-air circulating passages and a drying box supporting device to form a whole, the upper part hot-air circulating passage and the lower-part hot-air circulating passage are respectively connected with the upper and the lower ports to collectively form a hot-air circulating closed passage which is respectively used for the outflow of the heated hot-air and the inflow of the used hot-air, the hot air flows uni-directionally inside the hot-air circulating closed passage, the components of the working chamber are fixedly connected with each other, the hot-air generator is separated from the drying box, and the components forming the working chamber are made of non-magnetic materials.

Description

technical field [0001] The invention relates to a high-temperature testing device, in particular to a non-magnetic high-temperature testing device. Background technique [0002] Existing industrial electric heating ovens, hot air circulation ovens, etc., the heating heat source mainly uses electricity, very few uses gas, fuel oil, and the heat transfer medium is mainly air, and a small amount is liquid substances. Its heating range is from room temperature to 500°C, and can be higher when appropriate, and the temperature control accuracy is generally ±2% FS (FS is the set point temperature). [0003] The existing oven is mainly composed of three parts: the box body, the electric heating system, and the automatic temperature control system. It is a vertical and horizontal box-type structure, and some are tunnel-type structures. In most cases, the air inlet is at the bottom of the oven, the exhaust port is at the top, and there is usually an adjustable exhaust window on the ...

AI Technical Summary

Problems solved by technology

[0007] (1) When conducting the electromagnetic performance test, the existing oven cannot meet the working requirement that the heating device does not interfere with the test components due to reasons such as strong magnetism or electromagnetic induction

[0008] (2) The temperature difference between different areas in the working room of the existing oven is relatively large, which cannot meet the working requirements of the test element for the temperature difference ≤ 1°C

[0009] (3) When testing the test components, more than one piece is carried out, and the test components are mostly slender parts (that is, the length and diameter are relatively large). If the existing oven is used, the energy consumption will be large

[0010] (4) The lengths of test components are different, the short ones are less than 1m, the long ones are 3-7m, or even longer. However, the existing ovens with fixed and unchangeable structural dimensions cannot meet the work requirements, or need to increase assets, etc. Satisfy
