A temperature-measuring dipping preheating furnace and a temperature-measuring method

Abstract

The embodiment of the invention discloses a temperature measurement impregnation pre-heating furnace and a temperature measurement method. The temperature measurement impregnation pre-heating furnacecomprises an impregnation pre-heating furnace and a temperature measurement device, wherein the impregnation pre-heating furnace comprises an impregnation pre-heating furnace main body and a sealing device; when the furnace is used, a first horizontal section is pulled outward, and a compression block compresses a compression spring; then a second horizontal section moves toward a pulling direction until the second horizontal section leaves away from a product containing device; a product is put into the product containing device; then the first horizontal section is released; under the actionof the compression spring, the compression block drives a thermocouple guide pipe to move toward the product containing device until the thermocouple guide pipe is in contact with the product; a thermocouple is inserted into the thermocouple guide pipe and is continuously inserted along a guide direction of the thermocouple guide pipe until the thermocouple reaches the center of the product; thentemperature measurement is started to finish the temperature measurement. The temperature measurement impregnation pre-heating furnace can be used for effectively measuring the temprature in the product and conditions that the temperature on the surface of the product is too high and the surface quality is relatively poor so that subsequent processing is influenced are prevented.

Description

technical field [0001] The invention relates to the technical field of dipping technology, in particular to a temperature-measuring dipping preheating furnace and a temperature-measuring method. Background technique [0002] In the production of graphite electrodes, the impregnation process is a process to reduce the porosity of the product and improve the quality of the product. It is an essential and important process for the production of electrode joints and high-power and ultra-high-power electrodes. The impregnation preheating furnace refers to the furnace for preheating the products to be impregnated. According to the requirements of the dipping process, the product should be preheated to 200~250°C before dipping. This is an important condition to improve the impregnation effect. The method of making catalyst with impregnation as the key and special step is called impregnation method, which is also a method widely used in the industrial production of target catalyst...

Problems solved by technology

However, the method of judging the temperature of the product by judging the temperature in the immersion preheating furnace can only obtain the temperature of the surface of the product, but the temperature inside the product is unknown

Usually, when heating, in order to raise the temperature inside the product to the temperature required by the final effect of the product, the preheating time can only be lengthened, which will cause the surface temperature of the product to be too high. The pores on the surface of the product are blocked, so it is not easy to impregnate, and a lot of impurities will accumulate on the surface of the product, which will affect the subsequent processing
