The present invention also relates to a cooling element for a furnace comprising at least one steel insert arranged at its periphery and to the use of the smelting furnace in a direct iron reduction process, electric smelting process, electric reduction process, flash smelting process, flash converting process, bath smelting process or bath converting process.

This invention discloses a flash metallurgical system based on photothermal power generation and photolysis hydrogen production. The photolysis hydrogen production system collects solar energy and produces hydrogen through photolysis of water. The flash smelting system uses the hydrogen produced by the photolysis hydrogen production system to smelt metals. The integrated compressed air energy storage and generation system generates electricity through a turbine air generator to power the flash smelting system. The automatic control system uses a PLC programmable logic controller to coordinate and control the photolysis hydrogen production system, the flash smelting system, and the integrated compressed air energy storage and generation system. This system mainly uses a high-temperature molten salt reactor as the direct heat source for flash metallurgy. The photolysis hydrogen production system produces the hydrogen required for the metal reduction reaction, eliminating the dependence of metal smelting systems on traditional fossil fuels and enabling more efficient and high-quality completion of the metal smelting process. The use of compressed air energy storage and a turbine air generator system replaces the traditional steam power generation system, reducing dependence on water resources.

The application discloses a direct smelting process for treating lead paste of waste lead storage battery. The lead paste is converted into artificial lead concentrate with stable composition, appropriate granularity and dryness through physical and chemical pretreatment, and the artificial lead concentrate is adapted to process conditions of suspension flash smelting, so that efficient, clean and continuous treatment of the lead paste is realized.
