Description
Technical Field
The utility model relates to a device for checking water under high pressure descaling nozzle user state.
Background
The first process of steel strip rolling is to heat a steel billet, the steel billet is heated in a heating furnace to form a compact and thick iron oxide scale layer, the steel billet comes out of the heating furnace and enters a roughing mill set for rolling after descaling, secondary iron oxide scale can be formed on the surface of the steel billet due to the high surface temperature of the steel billet, the steel billet enters a finishing mill set for rolling after descaling when secondary oxidation, if the secondary iron oxide scale is not completely removed, the steel strip can be pressed in the finish rolling process, so that the defects of pits, iron spots, iron oxide scale pressing and the like are generated on the surface of the steel strip, and the surface quality of the steel strip is seriously influenced. High-pressure water descaling is an essential process in the steel rolling process, and has great significance for the whole rolling process; the nozzle is a main executor of the high-pressure water descaling system and is the key for determining the descaling effect. In the actual industrial production, the high-pressure water descaling machine is used under high load for a long time, and the descaling effect is seriously influenced by the blockage of a nozzle for high-pressure water descaling or the overlapping phenomenon caused by the change of the angle of the nozzle in consideration of factors such as the production site environment, the descaling water quality and the like.
In order to ensure that the high-pressure water descaling effect is good, each descaling nozzle needs to be ensured to be in a normal working state. The conventional inspection method used at present is to apply paint on the surface of a transition steel plate for inspection, and firstly, the inspection effect is influenced by considering that the adhesion of the transition steel plate is different due to the weak change of the thickness of the paint coating; and secondly, the test blank needs to be repeatedly painted in each test, so that the energy conservation and environmental protection properties need to be improved.
