In the production and research and development process of magnetic materials such as nickel zinc, manganese zinc cobalt, neodymium iron boron, etc., it is necessary to determine the firing temperature (pre firing temperature) for the production process of new materials; Accurate kiln temperature is also required for sintering secondary magnetic material products in order to stabilize the electrical performance indicators of magnetic products.

Kilns generally transmit the temperature of the kiln through thermocouples. However, due to factors such as different manufacturers, kilns, and specifications, thermocouples are also difficult to unify temperature measurement standards within the same enterprise, which can easily lead to discrepancies between the firing temperature tested by the R&D department and the actual temperature controlled by the production department, causing inconvenience to production.

The temperature measuring ring can accurately provide the actual temperature effect inside the furnace (i.e. the accumulated heat effect of the product), and can track the quality of the accumulated heat required for magnetic material products. At the same time, it objectively records the daily temperature changes in the furnace, providing accurate data information as the archive data for temperature quality tracking, which is conducive to implementing the ISO quality tracking management system and achieving the unity of internal research and development and production temperature control standards, Reduce the complexity of sintering temperature changes caused by different batches of raw materials.
