[0032] The present invention will be further described in detail below in conjunction with the embodiments.
[0033] A manufacturing method of SUS304 stainless steel cold-rolled plate with BA surface on both sides, including the following process path and specific control:
[0034] 1) Black-skin hot coil annealing and pickling (APH): the hot-rolled black-skin steel sheet is subjected to heat treatment at an annealing temperature of 1060~1130℃, and the steel plate is broken by a shot blasting process at a speed of ≤1670rpm, and then pre-pickled with sulfuric acid. Mixed acid (HNO 3 +HF) The production process removes the oxide scale generated on the surface to ensure that the surface of the product after pickling has a low surface roughness;
[0035] 2) Multi-roll mill rough rolling: Use a 20-high mill to perform rough rolling with a reduction rate of 10-30% on the hot pickled product to correct the shape of the steel coil to facilitate rough grinding;
[0036] 3) Rough grinding: Grind...
