In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This BV AH40 passenger-cargo ship steel production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate BV AH40 passenger-cargo ship steel size.
Water cutting machine is called water knife for short, that is, water is used as knife. High pressure water jet cutting technology can perform any curve cutting process on any material, BV AH40 passenger-cargo ship steel included. The heat generated in the cutting process will be immediately taken away by the water jet without harm. Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.
VLE460 steel plate grade analysis: "VL" stands for the abbreviation of "DNVGL", which is the standard certified by the two classification societies of DNV (Norway) and GL (Germany). VL E460 hull steel characteristics: good welding and other properties. It is suitable for repairing ships and main structures of naval vessels. Naval steel is required to have higher strength, better toughness, blast resistance and resistance to deep water collapse.
The company adheres to the principle of integrity, standardization and efficiency, wins the market with technology, gains reputation with creative services, and wholeheartedly provides customers with high-quality BV AH40 passenger-cargo ship steel, efficient and fast services. Facing the future, adhere to independent innovation.
