A strip position detection device for water cooling section

Abstract

The invention discloses a slab band position detecting device for a water cooling zone. A roller bed bracket below a roller bed of a water cooling zone frame group is provided with the slab band position detecting device consisting of a fixedly-mounted component and a rotational component; the rotational component is connected with the fixedly-mounted component; specifically, a bearing outer sleeve is sleeved on a connecting rod of the rotational component and is fixed by using a bearing and a fixing bolt so that the bearing outer sleeve can rotate at the connecting rod; the left end and right end of the bearing outer sleeve are respectively connected and provided with the connecting rod; the connecting rods at the two ends are in a lever shape; the connecting rod at the right end is provided with a water bearing plate; the surface of the water bearing plate is aligned with a position below a water spraying pipe; the connecting rod at the left end is arranged between an upper connecting rod detent and a lower connecting rod detent, and the end of the connecting rod is further provided with an induction bolt; the upper-limit movement locus of the induction bolt is coincident with aproximity switch and is limited by the upper connecting rod detent; and the lower-limit movement locus of the induction bolt is limited by the lower connecting rod detent. The device provided by the invention is applicable to the position detection field of the auxiliary calibration of a slab band position in a hot rolling and water cooling zone.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to a device for detecting the position of a hot-rolled steel plate / strip passing through a water-cooled section of a hot-rolled iron and steel production line. Background technique [0002] At present, various iron and steel production enterprises have widely used complete sets of hot steel hot rolling production line equipment in their hot steel rolling production. Among them, one of the key parts of the hot rolling production line - the water cooling section, whether the section is working normally or not It directly affects whether the production of the whole hot rolling production line goes on smoothly. [0003] The key to the normal operation of the water-cooled section is that when the hot-rolled steel sheet / strip (abbreviated as the strip) runs in this position section, whether its position detection mechanism can operate normally, while the hot-rolled line water cooling in t...

Problems solved by technology

[0011] The electric position sensor is not suitable for the use of the water-cooling section. The reason is that the roller table, nozzle, steel plate and other devices in the water-cooling section are all metal parts, and the electric position sensor cannot obtain accurate electrical signals. Therefore, the effect of directly using the electric position sensor is relatively low. Difference

[0012] To sum up, the detection methods in the existing technology are either because of their high cost or because they cannot adapt to the working conditions of the water-cooled section, which makes it difficult to detect the position of the strip when it passes through the water-cooled section of the hot-rolled steel production line. , which directly affects the follow-up production work. In severe cases, detection errors will cause plates and strips to collide with each other, causing safety production accidents
