Title (EN) STAINLESS-STEEL AND SMELTING PROCESS THEREOF
(FR) ACIER INOXYDABLE ET SON PROCÉDÉ DE FUSION
(ZH) 一种不锈钢及其冶炼工艺
Abstract: front page image
(EN)A stainless-steel and smelting process thereof, the process being a novel process directly employing nickel ore concentrate and continuously smelting the stainless-steel via calcining, an RKEF system, an AOD furnace, and an LE furnace; slabs are made via a continuous casting system, and Fe of the nickel ore concentrate after being calcined is used for preparation of crude nickel alloy in an RKEF furnace.
(FR)L'invention concerne un acier inoxydable et son procédé de fusion, le procédé étant un nouveau procédé consistant à utiliser directement un concentré de minerai de nickel et à faire fondre en continu l'acier inoxydable au moyen d'une calcination, d'un système RKEF, d'un four AOD et d'un four LE; à réaliser des brames par l'intermédiaire d'un système de coulée continue, et à utiliser du Fe du concentré de minerai de nickel après sa calcination pour la préparation d'un alliage de nickel brut dans un four RKEF.
(ZH)一种不锈钢及其冶炼工艺。所述工艺是直接采用镍精矿经过焙烧、RKEF系统、AOD炉、LF炉连续冶炼不锈钢的新型工艺,并通过连铸系统制作成板坯,镍精矿经过焙烧后其中的Fe用于RKEF炉中粗镍合金的制备。
