Abstract

By comparing the production indexes of large blast furnaces (BF) in China between the first half of 2019 and 2015–2016, the production status, reductant consumption, raw materials and operation conditions have been reviewed. In the first half of 2019, Chinese large BFs still had made a lot of achievements, but it is also discovered by comparison that not only the raw materials quality but also the large BFs stability have the trend of getting worse, so some work should be done to stop and recover the unfavorable situation. Based on that, the expectations of enhancing the raw materials quality and improving the operation conditions are suggested. Large BFs make great contributions to energy saving, low-carbon, high automatic, environmental protection and economic development, so there will be more large BFs constructed and put into production in China in the future.
