传统的高炉炼铁法是一项复杂而庞大的生产工艺。从矿石到生铁要经过许多生产环节,原燃料经过反复加热、冷却和加工,大大提高了产品的成本和能耗。办了改变这一现状,炼铁工作者一直在努力寻求新的炼铁工艺。作为一种能耗低、能源结构适应性强的炼铁新工艺—熔融还原法,在最近几年已引起了全世界的普遍重视。已报道的熔融还原法种类很多,目前大 The traditional blast furnace ironmaking method is a complex and huge production process. From ore to pig iron to go through many production processes, the original fuel after repeated heating, cooling and processing, greatly improving the product cost and energy consumption. Doing this to change the status quo, ironworks workers have been working hard to find a new ironmaking process. As a low energy consumption, energy structure adaptability of iron smelting new technology - reduction method, in recent years has attracted widespread attention around the world. There have been many different types of smelting reduction methods reported so far
