Steel plate descaling device based on slurry ejection and ultrasonic guided wave composite

Abstract

The invention discloses a steel plate descaling device based on the combination of slurry ejection and ultrasonic guided wave. The three descaling mechanisms, the steel plate scouring mechanism, and the air drying mechanism are arranged and connected in sequence, and an image detection mechanism is installed between two adjacent descaling mechanisms. Mechanism connection, the two image detection mechanisms and the three descaling mechanisms are respectively connected with the industrial computer. The invention is highly efficient, environment-friendly, energy-saving, and has no secondary pollution: the descaling of the upper and lower surfaces of the steel plate is achieved by using electromagnetic ultrasonic waves to cause microscopic vibrations and the scouring of water and metal abrasives, which improves the descaling efficiency of the steel plate, reduces costs, and has no pollution to the environment; Image detection technology is used to intelligently judge the descaling effect, and then control the number of openings of the descaling mechanism, saving materials and energy; using ultrasonic pulsating high-pressure water to wash the surface of the steel plate, reducing the power of the water pump, which is more energy-saving and effective.

Description

technical field [0001] The invention relates to a steel plate descaling device, in particular to a steel plate descaling device based on the combination of slurry projection and ultrasonic guided wave. Background technique [0002] Currently available steel plate descaling methods: [0003] 1. Tool descaling mainly uses wire brushes and other tools to polish the steel surface, which can remove loose or lifted scale, rust, welding slag, etc. Hand tool descaling can reach Sa2 level. However, the low efficiency of tool descaling cannot realize product automation, and it is relatively harmful to human body. [0004] 2. Pickling and descaling Chemical pickling can remove scale, rust, and old coatings. Although chemical cleaning can achieve a certain degree of cleanliness and roughness on the surface, pickling is prone to over-corrosion and hydrogen embrittlement, and acid mist is harmful to the human body and the environment.

Problems solved by technology

However, the treatment of the steel plate by shot peening is easy to deform the workpiece, causing great environmental pollution, and can only be operated in a closed space.

[0006] 4. Slurry descaling. Although U.S. patents US7601226 and US6814815 have made corresponding descriptions on steel plate descaling and cleaning steel plates with steel brushes, the steel plates cleaned by this method will immediately return to rust when in contact with air, which cannot be removed with steel brushes. There are traces of secondary repair on the surface of the steel plate, and the fine particles on the surface cannot be completely removed with a steel brush and normal pressure water

The surface of the produced steel plate is relatively dirty
