Steel plate surface treatment device and steel plate surface treatment method

Abstract

The invention provides a steel plate surface treatment device and a steel plate surface treatment method. The steel plate surface treatment device comprises a rack, a feeding device, a monitoring device, a rolling plate device, a sweeping device, a discharging device, an air source supply device, a laser double-face cleaning device, an oxidized waste treatment device, a control device and a safety protection device, and the feeding device, the monitoring device, the rolling plate device, the sweeping device, the discharging device, the air source supply device, the laser double-face cleaning device, the oxidized waste treatment device, the control device and the safety protection device are arranged on the rack. A steel plate is fed through the feeding device, is rolled to be flat through the rolling plate device, enters the laser double-face cleaning device to remove surface metal oxide, is subjected to oxidized waste sweeping through the sweeping device, is subjected to dust removal through a scraper dust removal device, and finally enters the discharging device to be discharged. After the oxidized waste is collected, secondary cyclic utilization of metal oxide is completed through the oxidized waste treatment device. Compressed air provided by the air source supply device is environment-friendly energy, so that steel plate production is neat and pollution-free; the electrical automation efficiency is high, and the occupied area is small; protection is standard, and unmanned production can be achieved; and the oxidized waste is reutilized, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to a steel plate surface treatment device and a steel plate surface treatment method, belonging to the field of industrial production. Background technique [0002] After rough rolling, when the steel plate rolls to the hot continuous rolling mill along the roller table, the temperature is about 1000°C. At this time, a thin layer of metal oxide skin has formed on the surface of the rolled piece, and the high-pressure water descaling before rolling The machine can remove them. When the rolled piece is rolled on the continuous rolling mill, the exposure time of the slab between the rolling mills of each stand is extremely short, and the large reduction hinders the formation of a thick metal oxide scale on the surface of the strip, and the formed oxide film It is immediately destroyed and washed by water. Therefore, it can be said that the strip steel that has just come out of the finishing stand has a relatively high temperature of...
