As the leading enterprise of vanadium and titanium industrialization in China, Chenggang has always dedicated itself to the integrated development and utilization of vanadium and titanium resources and the independent innovation of vanadium and titanium technology. After many years of practice, it has formed a number of vanadium and titanium production technology with complete independent intellectual property rights.
Recently, the vanadium-iron smelting production technology of Chenggang “a method of equalizing and prolonging the age of the electric ferro-ferroalloyed vanadium-iron smelting furnace†has won the national invention patent and has guiding significance for the development of the industry. This invention patent breaks through the life-span of refractories at the bottom of the furnace and becomes a "short board" that affects the furnace life of smelting ferro-vanadium. It solves the problems that need to be solved urgently for smelting the age of ferro-vanadium electric furnace. Through the simultaneous repair of the furnace wall and the bottom of the furnace to equalize and extend the electric silicon thermal method vanadium iron smelting furnace life, not only to repair the bottom of the furnace, but also to process the bottom of the furnace, while prolonging the furnace, while reducing the silicon Iron, quicklime dosage, increase vanadium yield, increase single furnace production, reduce costs, reduce the effect of waste emissions.
