Problems solved by technology

Since the middle guard plate is made of conventional ordinary carbon steel, when the steel belt is clamped, impurities such as iron filings will fall due to severe friction, and may adhere to the gap between the middle guard plate and the roller table. Impurities will affect the normal o

Abstract

The invention relates to a front roller bed purging device of a coiler of hot rolling. The front roller bed purging device comprises side guide plates, a middle protecting plate and roller beds. The side guide plates are arranged on two sides of the roller bed and are located above a roller bed plane, the opening degrees of the side guide plates can be adjusted according to width of strip steel, the middle protecting plate is mounted on substrates on the inner sides of the side guide plates, high pressure nozzles are separately arranged at two ends below a space between two adjacent roller beds, and the high pressure nozzles are connected to a side water spraying system through a high pressure water pipe. The front roller bed purging device of the coiler of hot rolling can purge scrap ironimpurities between the front roller bed and the middle protecting plate of the coiler of hot rolling in a hot rolling production process, can avoid blockage of the roller beds as the scrap iron impurities block gaps between the middle protecting plate and the roller beds, prevents the lower surface of the strip steel from being scratched as a result of blockage of the roller beds, and reduces theoccurrence rate of defects of a hot-rolled coil effectively.

Description

technical field [0001] The invention relates to the technical field of metallurgical hot rolling equipment, in particular to a front roller table cleaning device of a hot rolling coiler. Background technique [0002] The front roller table of the hot rolling line coiler is a conventional equipment, and its function is to transport the strip rolled out of the finishing mill to the coiler for coiling. There are 19 roller tables in total in front of the coiler, and there are side guide plates on both sides Device, the side guide plate device is equipped with a middle guard plate. During production, the middle guard plate on the side guide plate has a certain clamping force on both sides of the strip steel. The function is to keep the strip steel centered and enter the coiler, so that the coiler Machine-coiled steel coils are aligned with no defects such as tower shape and staggered layers. Since the middle guard plate is made of conventional ordinary carbon steel, when the ste...
