替代炼铁工艺与高炉工艺路线竞争。高炉是最重要的铁水生产商，多年来一直在改进，并将继续这样做。因此，更换高炉是一项艰巨的任务。替代工艺的成功率很低，即仅限于特殊用途。我们为什么要继续在这个领域工作？因为开发替代工艺的驱动力非常强大。例如，1980-1990年期间，预期的焦炭短缺一直是欧洲以煤为基础的发展的驱动力。最近的一些事态发展是在这一时期所做工作的基础上发展起来的。后来，在2000年前后，气候变化问题成为发展的驱动力。过去十年铁矿石的高价格水平可能会刺激新一轮的炼铁发展。HIsarna替代炼铁工艺是结合了上述几个驱动因素的发展的一个例子。该工艺有可能大大减少每吨二氧化碳的排放量。但它也可以使用价格更经济的原料，如非炼焦煤和高炉炼铁质量范围以外的铁矿石。因此，该方法可以提供经济效益以及环境效益。
Alternative ironmaking processes compete with the blast furnace process route. The blast furnace, the most important hot metal producer, has improved over the years and continues to do so. Consequently replacing the blast furnace is a formidable task. The success rate of alternative processes has been low, i.e. limited to niche applications. Why do we continue to work in this field? Because the drivers to develop alternative processes are very strong. For example, the expected coke shortage has been the driver for coal based developments in Europe in the period 1980–1990. Some of the recent developments evolved from the work done in that period. In later years, around the year 2000, the Climate Change issue became the driver for development. And the high price level of iron ore of the last decade can spur a new wave of ironmaking developments. The HIsarna alternative ironmaking process is an example of a development that combines several of the drivers mentioned above. The process has the potential to considerably reduce the CO2emissions per ton. But it can also use more economically priced raw materials such as non coking coals and iron ores outside the quality range for blast furnace ironmaking. Therefore the process can offer economic benefits as well as environmental benefits.
