AI Technical Summary
In existing antimony smelting technologies, a single injection system makes it difficult to achieve dynamic and precise control of oxygen potential, resulting in problems such as low direct antimony recovery rate, high antimony content in slag, high return rate, high energy consumption, and short furnace lining life.
A multi-stage injection method is adopted, dividing the smelting process into three stages: feeding and preheating, intensified smelting, and stabilization and refining. Different injection speeds, number of injection guns, and diameters are used in each stage. Combined with real-time monitoring and dynamic adjustment of injection parameters, precise control of oxygen potential and optimization of molten pool stirring are achieved.
It significantly improves the direct antimony recovery rate, reduces the antimony content in slag and the return rate, extends the furnace lining life, improves production efficiency and energy utilization, reduces dust generation, and lowers environmental protection costs.
