The production process of weathering steel plate mainly includes smelting, continuous casting, rolling and surface treatment. During the smelting process, it is necessary to add an appropriate amount of alloy elements to promote the formation of an oxide film on the surface of the steel. During the continuous casting process, the cooling rate and temperature need to be controlled to avoid cracks and surface defects. During the Rollingprocess, flera rullande processer krävs för att erhålla finkornstruktur och god ytkvalitet . Slutligen, under ytbehandlingsprocessen, kan väderstålplattan skjutas, målas, etc . för att förbättra dess korrosionsmotstånd och estetik .}
It is worth noting that the production process of weathering steel plate has an important influence on its performance. Reasonable smelting and rolling processes can ensure the uniformity and density of the internal structure of the steel plate, thereby improving its strength and toughness. The surface treatment process can further improve the weathering resistance and appearance quality of the steel plate.
