AI Technical Summary
Traditional diversion sand causes secondary pollution of molten steel during the pouring process, affecting the quality of the steel. Furthermore, the operation is complex, inefficient, and difficult to completely remove, thus affecting production rhythm and safety.
Prefabricated metal plugging components are used to replace traditional diversion sand. Combining the principles of self-propagating oxidation reaction and heat conduction, the metal plugging components achieve efficient plugging and automatic pouring of molten steel. The plugging materials are selected from metals and their alloys such as Fe, Al, Mg, Mn, Ni, Ti, Cr, Mo, V, Cu and rare earth elements. The heating is increased by heat conduction and a self-propagating oxidation reaction occurs during pouring.
It significantly reduces inclusions and oxygen content in molten steel, simplifies operating procedures, improves production efficiency, reduces steel quality problems, and is suitable for large-scale industrial applications.
