Description
Technical Field
The utility model discloses steel sheet finish rolling descaler test technique, concretely relates to blank in middle of the finish rolling descaler test.
Background
The high-pressure water descaling technology is applied to the hot rolling process of steel and is used for descaling the iron scale before rolling the steel. High-speed water flow sprayed by the high-pressure water nozzles strikes the upper surface and the lower surface of a rolled piece, and iron scales are loosened by the impact of high-pressure water; meanwhile, the surface temperature of the rolled piece is rapidly reduced to lead the oxide scale to generate cracks to be washed away under the difference of the linear expansion coefficients, thereby achieving the purpose of removing the oxide scale.
In production, a hot plate blank is coiled at a high speed by a hot coil box and then is conveyed to a finishing mill by a roller way, and descaling is carried out by a descaling machine in the process, and the descaling effect is influenced by the distance between a descaling header of the descaling machine and the upper surface of the plate blank, the jet angle and the like. The upper descaling manifold is fixed at the inlet of the finishing mill, and the height of the guide cannot be adjusted, so that the better descaling effect can be coordinated only by controlling the thickness of the plate blank. The thickness of the coil box fed to the first finishing mill (seven pass rolling) ranged from about 20-50mm. Because the thickness variation range of the intermediate blank bitten by the finishing mill is small, the descaling effect of most finishing mills is ensured by the thickness of the intermediate blank on the aspect of adjusting the height parameters. Therefore, before the hot rolling equipment is started, a plate beating test needs to be carried out, and the optimal slab thickness suitable for the system is determined through the plate beating test.
In the prior art, the plate beating test is to punch a cold blank on line, place a cold steel plate on a roller way, and pass through a descaling machine and a hot rolling machine by conveying the roller way so as to test the operation effect. It is often necessary to replace slabs of different thicknesses and to perform multiple tests to determine the preferred thickness for use. The steel plates with different thicknesses need time for replacement and hoisting, so the time spent on the plate beating test is long, and the spray state of the descaling header is protected during the steel plate conversion period, so a large amount of water resources are wasted. On the other hand, the cold blank for the plate beating test is a solid steel plate, the cold blank is heavy in weight and hard in structure, the impact on a roller way is large, the service life of a roller way carrier roller is easy to reduce, and if roller way locking is caused in the test, the hot blank can be scratched by the locking carrier roller in later normal production.
