Example Embodiment
[0010] The specific embodiments of the present invention are described below in conjunction with examples, but the specific embodiments of the present invention are not limited to the following examples.
[0011] In this embodiment, the 0Cr18Ni9 steel strip is removed. In this embodiment, three shot blasting machines work continuously in sequence to remove the steel strip after the first one is cleaned by the second one, and finally the third one.
[0012] SM150 steel grit is added to the silos of the three shot blasting machines, and SM150 steel grit is used to remove the scales on the surface of the stainless steel hot-rolled steel plate. The blasting coefficient is 1.1 to 1.2; the blasting speed of the shot blasting machine is 1850 to 2000 revolutions per minute ; The annealing temperature of the stainless steel hot-rolled steel plate should be 1130℃; the pressure current of the brush roller of the pickling section after cleaning is 25A, the pressure of the cleaning water is 5-...
