中国电炉炼钢问题 傅杰1,毛新平2,柴毅忠1 (1.北京科技大学冶金与生态工程学院,北京,100083;2.广州钢铁企业集团CSP应用技术研究所,广东,广州,510730;3.广州珠江钢铁有限责任公司技术中心,广东,广州,510730) 摘要:回顾了我国电炉炼钢发展情况,指出:由于目前我国废钢及电力紧缺,电炉钢成本较高,电炉炼钢存在一定困难,中国电炉钢的比例正面临着1990年以来第二次逐年下降的局面.使我国电炉钢生产走出困境的措施主要有3条,一是生产高附加值钢;二是通过电炉加部分铁水冶炼和强化用氧,缩短冶炼周期,降低成本;三是引导企业发展现代电炉,进行第二轮投资. 关键词:现代电炉炼钢......
电炉型式和设备选择 冯起1 (1.马鞍山钢铁设计研究院) 摘要:电炉炼钢近年发展很快,尤其DC电炉炼钢成为一种新潮流,AC和DC炉型派生多种多样,因此要结合具体条件选择优良的电炉炉型.选用电炉设备要立足国内,若从国外引进要对比选择.二手电炉和翻新电炉技术水平低,一次投资省但生产成本高,得不偿失,不宜选用. 关键词:电炉; 型式; 设备; [全文内容正在添加中] ......
