The method of distinguishing manganese plate from common carbon steel plate, A573 Gr 70 carbon steel plate is as follows:(1) Check the spray labelWhether it is manganese plate or common carbon steel plate, it has its own factory spray mark, just check it;(2)Listen to the cutting soundThe cutting sound of manganese plate is relatively clear and crisp, while that of common carbon steel plate is not clear and crisp, and the manganese plate will fall off as soon as it is cut;(3) Look at the polishing sparksLook at the amount of sparks on the surface during polishing. The more sparks and forks are manganese plates, and the lesser ones are common carbon steel plates;(4) Check the material certificateGenerally, the material certificate will clearly indicate what material it is, just check it.
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 A573 Gr 70 carbon steel plate, hot-rolled seamless steel tube by continuous rolling mill.
The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, A573 Gr 70 carbon steel plate flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.
