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 S420ML steel h beam 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 S420ML steel h beam size.
15Mo3 steel manufacturing method: adopt oxygen top blown converter method, 182 open hearth method or 3666 to smelt in 3769 electric furnace. After negotiation with the customer, other equivalent methods can also be adopted.15Mo3 steel is used for heating surface pipes, economizers, superheaters, reheaters, etc. of high-pressure boilers S420ML steel h beam (working pressure is generally above 9.8MPa, working temperature is between 450 ℃ ~ 650 ℃).
