How to measure furnace temperature in high temperature electric furnace
High temperature electric furnace is used for the heating of precision experiments, the furnace temperature is the key factor to ensure the success of the experiment, the quality of the heating workpiece also depends on the high temperature furnace furnace temperature control, it can be said that the timely grasp of the furnace temperature condition is the high temperature furnace work quality and efficiency guarantee. Therefore, the importance of high temperature furnace temperature measurement work is self-evident.
High temperature electric furnace is according to the temperature ring in the absorption of heat will shrink to complete the temperature measurement work, according to the temperature ring and the cumulative heat burning products, the conversion of the test temperature. The temperature setting ring can be placed in any position in the high temperature electric furnace, such as kiln furniture, kiln car or carrier plate, or together with the heating workpiece. The shrinkage rate of the diameter of the calibration ring accurately reflects the actual temperature of the calibration ring in a high temperature electric furnace. It is easy to measure the diameter of the temperature - setting ring after firing by the common 1000 - minute calipers. For accuracy and convenience, a special conversion table is attached to each batch of calibration rings. Please note that the batch number on the calibration ring must be the same as that on the temperature conversion table for proper use.
There are many advantages in measuring furnace temperature with calibration ring for high temperature electric furnace. The calibration ring is flexible and easy to measure any corner of three-dimensional space in the furnace. The setting temperature ring is placed in the position closest to the actual heating condition of the product, and the heating condition of the burned product is accurately determined. The use of a temperature-setting ring can reduce or even eliminate the need for measurement or destructive testing of the geometry, density and porosity of the finished product, thereby reducing the cost of quality control in the production process; The temperature-setting ring has a good consistency, which can guarantee the good reproducibility of the firing system of the products, so as to improve the qualified rate of the finished products of the high-temperature electric furnace heat treatment.
It is a complicated process to measure the temperature of high temperature electric furnace. What the temperature measuring ring measures is the heat accumulated in the whole firing process, including radiant heat, conduction heat and convection heat, as well as the comprehensive effect of different holding time. It can not only measure the highest temperature reached by the burning products, but also reflect the heating state of the products in the process of heating the products by the high temperature electric furnace. Therefore, it can be said that in the high temperature electric furnace temperature measurement work, the role of the temperature adjustment ring.
