一、概述预热废钢的好处早巳为人们所知,它是电弧炉增加生产、降低成本的可行方法。但是,直到目前为止,这种工艺的常规方法一直是使用矿物燃料,如天然气或燃油,因此使预热废钢的经济效果降低。近年来,为了 I. INTRODUCTION The benefits of preheating scrap have long been known, as it is a viable way for EAFs to increase production and reduce costs. However, until now, the conventional approach to this process has been the use of fossil fuels, such as natural gas or oil, thus reducing the economic impact of preheating scrap. In recent years, in order to
