Effects of optimizing the insertion of thermocouples in gas furnaces

Atmospheric Muffle Furnace is widely used in the industrial field for sintering of magnetic cores in the magnetic materials industry, mainly for small laboratory trials and small batch production.
With the development of magnetic materials industry, miniaturization and integration of electronic devices, the market demand for high performance products is increasing, and accordingly the atmosphere Muffle Furnace has also raised higher requirements. Based on the shortcomings of the traditional atmosphere muffle furnace, combined with the specific requirements of the sintering process for the atmosphere muffle furnace, we carried out targeted improvement and optimization design.
Optimization of the thermocouple insertion method of the Atmospheric Muffle Furnace
The traditional atmosphere Muffle Furnace thermocouple is sealed in the furnace body as a whole, and its cold end is connected to the terminal block on the furnace body through the high temperature resistant compensation wire, which is then connected to the temperature control instrument. Due to the high temperature of the cold end of the thermocouple, resulting in the temperature of the temperature controller display temperature in the chamber of the furnace inconsistent, and a large difference. In the optimized design, the thermocouple is inserted into the chamber furnace from the top of the furnace body through two layers of iron plates, so that the temperature of the cold end of the thermocouple is lower, which ensures the consistency of the temperature displayed by the temperature controller and the chamber furnace temperature. But the need to seal the end of the thermocouple, and only a compensation wire connected to the outside world. After this improvement. Although each time before replacing the silicon molybdenum rod, the need to pull out the thermocouple, more trouble, but due to the longer life of the silicon molybdenum rod, the box-type furnace dragged out less often.
