This invention discloses a method for controlling carbon increase in molten steel based on slag system modification, comprising the following steps: S1, smelting endpoint control: controlling the carbon content, phosphorus and sulfur content, and tapping temperature of molten steel at the endpoint of converter or electric furnace smelting; S2, tapping alloying and initial carbon increase: adding a multi-element nitride alloy and a first carbon increaser to the ladle during tapping; S3, argon blowing and stirring: performing a first stage of high-flow-rate argon blowing and stirring; S4, argon blowing station fine-tuning: transporting molten steel to the argon blowing station for sampling and analysis, and supplementing with a second carbon increaser; S5, composition homogenization and soft blowing: sequentially performing a second stage of medium-flow-rate argon blowing and stirring, and a third stage of low-flow-rate soft blowing; wherein the mass percentage of manganese in the multi-element nitride alloy is ≥5%. The advantage of this invention is that by combining optimized alloy composition, segmented carbon increase, and gradient stirring, it achieves precise control of a narrow composition window in molten steel.

This invention relates to the field of vehicle tire steering angle control technology, specifically to an adaptive vehicle tire steering angle control system and method after parking. Through the cooperation of a sensor module, scene recognition module, data processing module, control module, and human-machine interaction module, the system determines the automatic tire steering angle control conditions and optimal tire steering angle based on whether the driver has left the vehicle, the type of slope the vehicle is on, ground conditions, and the distribution of surrounding obstacles. This allows the system to automatically drive the wheels to the appropriate angle after the vehicle stops, effectively improving safety when starting the vehicle and extending tire lifespan. By establishing a vehicle environment model, the system divides the automatic tire steering angle control conditions and converts the optimal tire steering angle for each condition into real-time control commands. This enables the system to execute corresponding control strategies based on different slope types, ground conditions, and obstacle distributions, resulting in more precise control of the wheel steering angle and maximizing the beneficial effects of automatic vehicle steering angle control.
