Abstract

The invention provides a multi-point temperature measuring device which comprises a mica tape, a tube body, a thermocouple, a first connecting section, a second connecting section, a plurality of temperature measuring sections and a top section; and the top section, the temperature measuring section, the second connecting section, the first connecting section and the tube body are connected into a whole through threads and screws. In such a manner, the roasting of a self-roasting electrode is monitored by measuring the temperature of an electrode roasting area, the structure is compact, the sensitivity is high, the effective temperature measuring points of the thermocouple are arranged in relatively independent temperature measuring sections, and the measuring data errors are 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 a self-baking electrode firing area and monitoring the firing condition 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 then baked to form a self-baking electrode. The outer layer of the self-baking electrode is a cylinder made of 1~2mm steel plate, and the electrode paste is regularly added to the cylinder. As the production progresses, the lower electrodes are 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 a liquid state. As...
