Problems solved by technology

[0002] At present, infrared thermometers are widely used for temperature measurement and control of induction furnaces. The advantage of this method is that it is convenient for temperature collection. Different positions of the billet can be scanned by the infrared thermometer to obtain the metal temperature on the outer surface of the heated ingot, which reflects the Induction furnace temperature uniformity, but the disadvantage of this method is that it can only reflect the uniformity of the billet temperature after the heated billet is heated out of the furnace, and cannot reflect the heating of the billet in the heating furnace in real time, and because the infrared thermometer scans different positions There is a time difference, there is a temperature drop, the temperature of the first measurement position is high, and the temperature of the second measurement position is low, which cannot accurately reflect the temperature uniformity of the upper, lower, middle, inner and outer metals of the heated billet at the same time

Abstract

The invention provides a furnace temperature measuring blank and a furnace temperature uniformity measuring method. The furnace temperature measuring blank and the furnace temperature uniformity measuring method using the measuring blank are included. The measuring blank is obtained as follows: a blank is drilled to obtain a perforated blank, and a temperature measuring device is inserted into a temperature measuring hole (1) of the perforated blank to obtain the measuring blank. The furnace temperature uniformity measuring method comprises the steps as follows: the measuring blank is connected with an electronic data recorder and placed in an induction furnace, the induction furnace is heated by a preset procedure, and data are read on the electronic data recorder. Compared with a traditional measuring method, the method can truly reflect material temperature condition in actual production, can ensure the blank heating temperature to meet the process technology requirement during workof the induction furnace, has higher practicability and can accurately reflect temperature uniformity of upper and lower ends, the middle and inner and outer metal of the heated blank, so that the induction furnace reaches the qualified state required by the process. The method can set induction heating process parameters of certain metal.
