摘要
结晶器液面结壳是合钛不锈钢连铸的主要问题之一。研究结果表明,保护渣有很强的吸氮能力,气氛、渣成分特别是含碳量会影响熔渣吸氮。渣中氮与钢液中钛能发生界面反应生成TiN。熔渣不能良好的吸收TiN和结晶器液面波动是形成结壳的根本原因。
The formation of crust in the mold is a significant problem during continuous casting of Ti-bearing stainless steels. Experimental results show that the molten flux in the mold has a strong ability of absorbing nitrogen, which will be influenced by the atmosphere and the molten flux composition particularly the carbon content. The nitrogen in molten flux can react with titanium in liquid steel to form titanium nitride at the [flux-steel interface. The poor flux assimilation for TiN from the liquid steel and...
