The utility model belongs to the field of bar rolling technology relates to a kind of high-precision special steel bar reducing sizing production system, including two two-high rolling mill, two three-high rolling mill, water tank after reducing sizing and finished product collection system being sequentially arranged along the rolling direction.The utility model is innovatively configured with the combination of 2 two-high rolling mill of low cost and 2 high-precision three-high rolling mill, and an efficient reducing sizing production system is constructed.Compared with traditional three-high rolling mill system, this design significantly reduces the number of expensive three-high rolling mill, thereby reducing equipment purchase and maintenance costs.At the same time, two high rolling mill leads the primary rolling of large-scale bar, effectively reducing energy consumption and production cost.This configuration ensures product precision while significantly optimizing cost structure, especially suitable for production scenarios with high economic requirements.

This invention relates to the field of new materials and electrochemical energy storage materials, and discloses a polyimide-derived hierarchical porous carbon / carbon fiber composite electrode and its preparation method. The preparation method involves using carbon fiber felt as a substrate, and constructing a three-level interconnected structure of micropores, mesopores, and macropores through polyimide solution spraying, metal-organic gel template deposition, gradient carbonization, and eutectic activation processes. This invention, through template synergy and optimized activation processes, enables the constructed composite electrode to possess a unique three-level interconnected structure of micropores, mesopores, and macropores, solving the problems of limited mass transfer and insufficient active sites in traditional carbon electrodes. It can be widely applied to all-vanadium, iron-chromium, and organic flow batteries, and has significant industrial application value.

This application relates to the field of power supply circuit technology, providing a high-voltage rectified and regulated power supply circuit system and a power supply control method. The system includes: a main voltage source for providing a target output voltage; a main switching circuit for converting the target AC output voltage into DC; a DC bus connected to the load; a clamping voltage source for providing a clamping voltage lower than the target output voltage; a clamping switch circuit for converting the AC clamping voltage into DC; an auxiliary voltage source connected to the DC bus; and a control unit for controlling the auxiliary voltage source to pre-charge the power devices in the circuit system before the main switching circuit and the clamping switch circuit are turned on; after pre-charging, power is supplied to the load through the DC bus by controlling the alternating conduction of the main switching circuit and the clamping switch circuit. This application, through the configuration of multiple voltage sources with similar voltage values ​​and an auxiliary voltage source, can establish a power supply system with stable output, low power storage requirements, and low specifications for power devices.
