超纯铁素体不锈钢因碳、氮含量极低,较普通铁素体不锈钢拥有更优越的耐腐蚀性、韧性及焊接性,近半个世纪得到了大力发展和广泛应用。对于超纯铁素体不锈钢冶炼的核心环节——不锈钢精炼,首先阐述了超纯净化、高洁净化、高效稳定化控制等一系列精炼技术难点,其次从精炼主体设备与工艺技术以及辅助技术等方面系统介绍了超纯铁素体不锈钢精炼技术的进步和发展,最后对超纯铁素体不锈钢精炼技术的未来革新和发展方向进行了一些展望。
Ultra-pure ferritic stainless steel due to carbon, nitrogen content is very low, compared with ordinary ferritic stainless steel has superior corrosion resistance, toughness and weldability, nearly half a century has been vigorously developed and widely used. For the refining of stainless steel, the core of ultrapure ferritic stainless steel smelting, firstly, a series of refining technology difficulties such as ultrapure purification, high purity and high efficiency stabilization control are elaborated. Secondly, from the aspects of refining main equipment, process technology and assistive technology The progress and development of ultrapure ferritic stainless steel refining technology are introduced systematically. Finally, some prospects of the future innovation and development of ultrapure ferritic stainless steel refining technology are discussed.
