The general-strength A and B grade marine steel plate can meet their technological and mechanical performance requirements through ordinary rolling, so the production process is relatively simple; while the production of D, E marine steel plate and high strength marine steel plate requires more complete equipment Under equipment, it can be realized by means of controlled rolling and controlled cooling process or heat treatment process.
At the same time, the inherent steel purity of the supplied billet is relatively high, especially the content of S, P, N, O, H, etc. in the steel must be strictly controlled.
In order to reduce costs, it is best to use hot rolling or controlled rolling instead of normalizing to produce ship plates. High-strength marine steel plate with a thickness of less than 35mm have been produced by two stage controlled rolling; high strength marine steel plate with a thickness of more than 35mm are mostly produced by hot rolling and normalizing.
