On-line position detection method of steel coil

Abstract

The invention relates to the field of steel coil positioning of a hot rolling strip steel coil discharging system, in particular to an on-line position detection method of a steel coil. The on-line position detection method is characterized in that a pair of laser range finders is parallelly arranged on one side of a conveying chain corresponding to a walking beam, and the two laser range finders respectively detect the position offset of the steel coil on the walking beam and the conveying chain, wherein the position offset includes position offset a1 of a steel coil central line and a buffer central line of the walking beam and position offset a2 of the steel coil central line and central line of the conveying line. When the offset a1 and the offset a2 of the steel coil exceed the limit value, the system is controlled to give out alarm signals, simultaneously coil discharging is stopped, operators can judge whether transportation can be performed normally, and if not, the operators can place the steel coils on the conveying chain through cranes. Compared with the prior art, the on-line position detection method has the advantages of being capable of timely detecting the position of the steel coil on the walking beam or the conveying chain, and avoiding the shut down accidents of coil falling due to coil inclination; and improving automation degree of the hot rolling strip steel coil discharging system and ensuring smooth production.

Description

technical field [0001] The invention relates to the field of steel coil positioning in a hot-rolled strip unwinding system, in particular to an online position detection method for steel coils. Background technique [0002] In the uncoiling system of hot-rolled strip steel, the steel coil is rolled by the coiler at the end of the rolling line, and then moves to the bundling station, walking beam, and conveyor chain in sequence, and is moved to the finished product warehouse through the conveyor chain, when more than 30 tons When the steel coil is misaligned on the walking beam or conveyor chain, it will cause uneven force on the walking beam or conveyor chain, serious wear and tear on the mechanism, and the most serious accident is a coil drop, which will damage the grating and bundle printers, inkjet printers and other equipment, resulting in major economic losses, while affecting the smooth flow of production.
