Abstract

The invention provides a connecting structure for a compensation lead in a heating furnace. The connecting structure comprises the compensation lead, the compensation lead is connected between a thermocouple and a measuring device, the thermocouple is arranged in the heating furnace, and the thermocouple is used for measuring the temperature in the heating furnace; the compensation lead comprisesa thermocouple connecting end, the thermocouple connecting end is connected to one end, extending out of the heating furnace, of the thermocouple, and a heat insulation layer is arranged between the thermocouple connecting end and the heating furnace; a heat insulation layer is arranged between a joint of the compensation lead and the thermocouple and the heating furnace, so that the influence ofheat radiation of the heating furnace on the compensation lead is reduced as much as possible, the influence of premature aging of the compensation lead on thermoelectric characteristics is avoided, and then the temperature measurement accuracy is ensured.

Description

technical field [0001] The invention belongs to the technical field of connection of compensation wires, and in particular relates to a connection structure of compensation wires used in a heating furnace. Background technique [0002] Thermocouples for temperature measurement are arranged in the annular heating furnace, and the thermocouples are connected to the operation room capable of displaying the measurement results of the thermocouples through compensation wires. The cold end of the thermocouple passes through the roof of the annular heating furnace, and the compensation wire and the cold end of the thermocouple are directly connected on the roof of the annular heating furnace, so that the distance between the compensation wire and the furnace roof is only 300mm. [0003] There are the following problems in the way that the above-mentioned thermocouple and the compensation wire are directly connected at the furnace roof of the heating furnace: [0004] 1. The short ...
