The invention discloses a 430 stainless steel rolling method. The chemical composition weight percentages are: C≤0.04%, 0.30%≤Si≤0.60%, Mn≤0.45%, P≤0.030%, S≤0.005%, Cr≤16.50% , N≤0.045%, 0.05%≤Re≤0.25%; the rest are Fe elements and other inevitable impurities; the specific steps of the rolling method are as follows: 1) Heating: the heating steps are sequentially divided into preheating section, heating section, 2) Rough rolling: The billet enters the rough rolling mechanism through the heat preservation transmission mechanism, and the rough rolling mechanism performs initial rough rolling on the heated billet; 3) Finishing rolling: After the rough rolling is completed, the billet enters the finishing rolling mechanism for finishing. Rolling treatment; 4) Coiling; 5) Decoiling welding; 6) Annealing; 7) Phosphorus breaking and shot blasting; 8) Pickling; 9) Cleaning: The surface of the pickled stainless steel plate is cleaned by a cleaning device; Dry. The present invention obtains a high-quality stainless steel plate through a reasonable ratio of raw materials and a rolling process, and ensures the surface quality of the stainless steel plate. |
