Development Test of Flexible Manufacturing Technology for 345MPa Grade Low-alloy Steel

Through the optimization of chemical composition design,rolling process and water-cooling process,Jinan Steel developed the flexible manufacturing technology for 345 MPa grade low-alloy steel. The products with different properties were rolled by the billets with same chemical composition,satisfying individuation demands of order forms,relieving the difficulty of production plan schedule and the production difficulty in steelmaking procedure and shorten the production cycle greatly.
