Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce spv355 asme, hot-rolled seamless steel tube by continuous rolling mill.
Service marketing type depth processing, deep processing is more convenient for the user, to provide users with intermediate product marketing value, its typical service for general shear distribution or marketing type spv355 asme steel processing distribution (including general steel coil storage, scale shear, and the steel bar straightening, shearing, bending, welding, etc) and the apparatus of processing and distribution center.
spv355 asme, SX780CF is a steel with high strength and low crack sensitivity. It is mainly used for manufacturing important structural parts such as volute and penstock in large hydropower units with an installed capacity of more than 10 million KW and high head energy storage power station. It needs to have high strength toughness, good cold deformation and weldability.
Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the spv355 asme steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its spv355 asme steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
