Abstract

The invention discloses an on-line monitoring device for furnace temperature of a motor iron core heat treatment tunnel furnace. The on-line monitoring device comprises a temperature measuring mechanism and a material frame used for placing motor iron cores; the motor iron cores are placed in the material frame in a stacked manner; the temperature measuring mechanism is placed on the side portion, located on the motor iron cores, of the material frame; a temperature measuring contact of the temperature measuring mechanism is arranged in the stacked motor iron cores or among the motor iron core stacks; the material frame with the temperature measuring mechanism and the motor iron core stack is integrally hoisted to a feeding roller bed of the tunnel furnace and operates along with the tunnel furnace to conduct heat treatment on the motor iron cores, and the temperature measuring mechanism monitors the real-time temperature on line. The problem that the actual temperature value of the whole furnace section of the motor iron core heat treatment tunnel furnace cannot be monitored on line in the production process in the prior art is solved, accurate monitoring of the heat treatment temperature in the tunnel furnace is achieved, a guarantee is provided for setting of the heat treatment temperature of the motor iron cores and the stacking amount of the iron cores, and the final performance of the motor iron cores during efficient production is guaranteed. An online monitoring method for the furnace temperature of the motor iron core heat treatment tunnel furnace is further disclosed.

Description

Technical field [0001] The present invention belongs to the field of furnace temperature detection, and in particular, the present invention relates to a motor iron core heat treatment tunnel furnace furnace temperature online monitoring device and a monitoring method. Background technique [0002] Non-tie silicon steel is mainly used to prepare core cores of various types of motors, but the processing stress brought by the core processing process will deteriorate the electromagnetic properties of no to silicon steel to affect the ultimate performance of the motor, so the iron core heat treatment is a common in the industry. To ensure motor performance, the precision control of the heat treatment temperature is also the key to ensuring the heat treatment effect of the motor. [0003] The tunnel furnace has the characteristics of continuous, bulk, and efficient production. It is widely used in the heat treatment of the motor core. The existing tunnel furnace temperature detection ...
