[0022] The alloying smelting method of vanadium-containing weathering steel for automobiles comprises the following process steps:
[0023] a. Pour 10 tons of high-phosphorus molten iron into an empty ladle and transport it to the converter taphole for standby; wherein, the main components of high-phosphorus molten iron are C: 4.0%, P: 0.15%, V: 0.32%, and Si: 0.1% , Mn: 0.3%, S: 0.03%, the rest are iron and unavoidable impurities, and the tapping temperature is 1390°C.
[0024] b. Pour 150 tons of converter-tapped molten steel into a ladle containing high-phosphorus molten iron, add 0.83 tons of ferrochrome, 0.45 tons of copper plate and 0.82 tons of silicon-manganese alloy, and blow CO at the bottom of the ladle to stir during the process of converter tapping , the alloying of phosphorus and vanadium is achieved through the impact of molten steel on molten iron and CO blowing and stirring. Among them, the molten steel from the converter is blown according to the converter s...
