The application discloses a kind of low-aluminum low-sulfur high-chromium high-nitrogen series pressure vessel steel and smelting method, belong to steelmaking technical field, its chemical component and weight percentage are as follows: C:0.06-0.15%, Si:0.2-0.5%, Mn:0.3-0.6%, P≤0.025%, S≤0.003%, Alt 0.005-0.015%, Cr:8.0-13.5%, Mo:0.8-1.2%, V:0.15-0.3%, Nb:0.05-0.1%, N:0.03-0.08%, the balance is Fe and other inevitable impurities.Smelting method is converter smelting, LF refining, RH vacuum treatment and conventional continuous casting.The application does not need to increase equipment, ensures deep desulfurization under low Alt condition, optimizes LF refining parameter, smelts high N high Cr steel using LF furnace, stably controls each component, so that the composition of molten steel meets the requirements.

The present application relates to the technical field of production line automation, and particularly relates to a production scheduling optimization method and device fusing equipment health degree, which evaluates equipment health degree by real-time collection of welding production line equipment operation parameters, and quantifies the process complexity of the to-be-scheduled vehicle model in combination with the welding process characteristics of the to-be-scheduled vehicle model; then a matching relationship between the equipment and the vehicle model is established by using an adaptability scoring model; finally, optimization matching is performed with the goal of maximizing the overall adaptability, a dynamic vehicle model-station production scheduling scheme is generated, and the scheme is updated according to the real-time state in the production process. The scheme matches and optimizes by constructing the adaptability scoring model of the two, so that the production scheduling scheme can dynamically adapt to the actual capacity of the equipment and the process requirements, thereby improving the rationality of equipment utilization and the stability of the production rhythm; in combination with the rolling update mechanism, the adaptability of the production scheduling system to changes is enhanced, and the optimization level of production efficiency and resource allocation is improved.
