Does anyone know the production technology of round steel?

Stainless steel round bars (≤40mm bars) are continuously produced by Morgan 45 two-high or Cox three-high (Y-type) rolling mills. The general product specification is 5.5 ~ 40 mm coil. The final rolling speed is 50 ~ 60m/s (ferritic stainless steel) or 70 ~ 60m/s (austenitic stainless steel). Due to the adoption of torsion-free rolling, the surface quality of stainless steel round steel products is bright and clean, and the dimensional accuracy is high. ≤? 0? The bar diameter deviation of 320mm wire rod can reach 0.65438 0 mm.. 0? The 340mm bar can reach 0.2mm, and the disc weight can reach 2t. Specific production process steps: material preparation, heating, descaling, rough rolling, cutting, intermediate rolling, cutting, finishing rolling, coiling, heat treatment, pickling and warehousing.
