Blast-furnace iron tap channel side wall thickness detection device and method thereof

Abstract

The invention discloses a blast-furnace iron tap channel side wall thickness detection device and a method thereof; the device comprises a base, a measuring rod, a sleeve, a push rod, a track plate and a bolt provided with a slate pencil, wherein the sleeve is connected with the base by a pin shaft; the measuring rod is inserted into the sleeve and can slide relatively to the sleeve; the push rod is connected with the measuring rod by the bolt provided with the slate pencil; the push rod is provided with a guide groove; the track plate is fixed on the base and is provided with a guide pin; and the guide pin is arranged in the guide groove. The blast-furnace iron tap channel side wall thickness detection device and the method thereof can be used for conveniently and accurately detecting the thickness of the side wall of a blast-furnace iron tap channel.

Description

technical field [0001] The invention relates to a thickness detection device and a method thereof, in particular to a blast furnace tapping channel side wall thickness detection device and a method thereof. Background technique [0002] The side wall of the tapping channel of the blast furnace will gradually melt and become thinner as the production progresses. When the thinnest part is less than the specified value, there is a danger of being burned through by molten iron. Once burned through, molten iron leaks to the hearth, which directly affects the operation of railways, torpedo tanks, various lines, and dust removal equipment, and the loss every time is huge. Therefore, it is particularly important to accurately detect the thickness of the side wall of the iron channel and know its melting loss rate for safe iron receiving. [0003] Since the tapping channel of the blast furnace has only one side for measurement, and the other side is closely connected with the hearth...

AI Technical Summary

Problems solved by technology

[0003] Since the tapping channel of the blast furnace has only one side to measure the space, and the other side is closely combined with the hearth, and is affected by the high temperature molten iron, the general thickness detection device cannot be used to measure the thickness of the side wall of the tapping channel of the blast furnace

[0004] In terms of measuring the thickness of the side wall of the iron trench at present, it is mainly to detect the side wall manually with a steel pipe. The thickness value is estimated by the operator, and the measurement accuracy is about 60%, which causes a large error and affects the Judgment on working condition of tap trough
