The invention relates to the technical field of converter smelting, and discloses a silicon-manganese alloy dynamic regulation and control method and system in a converter direct feeding process and a storage medium. The method comprises the following steps: acquiring molten iron components, temperature and furnace gas data, carrying out timestamp alignment and Kalman filtering to obtain synchronized smelting state data, substituting the silicon-manganese concentration, the temperature and the iron oxide content in slag into a rate equation, and carrying out numerical integration to obtain a dynamic oxidation loss curve; adjusting oxygen supply and slagging in the early stage of blowing according to the curve, monitoring the carbon-oxygen product in the middle stage, calculating the remaining decarburization time, determining an alloy adding time window, collecting parameters at the moment, inputting the parameters into the long-short-term memory neural network, predicting the yield, and inversely calculating the total alloy demand; and measuring the actual silicon-manganese content during tapping, calculating the comprehensive deviation ratio, and adding alloy in batches to obtain a target end-point component. The problems of inaccurate oxidation loss prediction, extensive yield estimation and lack of a dynamic feedback adjustment mechanism in the prior art are solved.
