Abstract

The invention provides a multi-point temperature measuring device, which includes a mica tape, a pipe body, a thermocouple, a first connecting section, a second connecting section, a plurality of temperature measuring sections and a top section, the The top section, the temperature measuring section, the second connecting section, the first connecting section and the pipe body are connected into a whole by threads and screws. Therefore, the present invention monitors the firing condition of the self-baking electrode by measuring the temperature of the electrode firing area, and the present invention has a compact structure and high sensitivity, and the effective temperature measurement point of the thermocouple is located inside a relatively independent temperature measurement section, so the measurement data error is small.

Description

Technical field [0001] The invention relates to a temperature measuring device, which belongs to the field of measurement and control. In particular, it relates to a multi-point temperature measuring device for measuring the temperature of the firing area of ​​a self-baking electrode and monitoring the firing of the electrode. Background technique [0002] Using anthracite, coke, pitch and tar as raw materials, the electrode paste is made at a certain temperature, and then the electrode paste is put into the electrode cylinder installed on the electric furnace, and the self-baking electrode is formed after baking. The outer layer of the self-baking electrode is a cylinder made of 1~2mm steel plate, and the electrode paste is regularly added in the cylinder. As the production progresses, the lower electrode is gradually consumed and the electrode paste moves down. At a temperature of 25°C to 120~200°C, the electrode paste gradually softens until it becomes all liquid. As the te...
