Built-in vacuum furnace temperature uniformity test system

Built-in vacuum furnace temperature uniformity test system

For the vacuum heat treatment equipment without temperature testing hole cannot be tested or vacuum furnace temperature test of complex due to the reason of its structure, design the online test system and test online.
Temperature in heat treatment process parameters is of vital importance, and temperature uniformity are important parameters of heat treatment process of heat treatment furnace requirements. At present, the domestic part of the vacuum heat treatment plant equipment without temperature uniformity measurement inspection hole, cause not through an external device, the measurement of temperature uniformity and system accuracy test. Another part of the vacuum heat treatment equipment test hole made on the equipment, but detection equipment damage, destruction furnace, some of the vacuum furnace heating element is composed of expensive components such as molybdenum, once broken, it brings huge economic losses, and even to temperature field uniformity testing work, the existing test methods is also very complicated.
Through to the device using the method and the working principle is analyzed, using built into, the measurement of temperature uniformity in the vacuum furnace, thermocouple data collector and the heat insulation box in the heat treatment furnace frame, the station frame according to the requirements of each customer testing techniques to customize, loading test for temperature field in the vacuum furnace, thermocouple data collector for parameter setting, including the acquisition time, acquisition interval and thermocouple type, etc., the internal temperature uniformity testing. System composition and the built-in vacuum furnace temperature on-line detection system is introduced in this paper is mainly composed of thermocouple data collector, heat insulation and the test of thermocouple.
