Abstract

This article has reviewed the production status, total reductant consumption, raw materials and operation principle indexes of large blast furnaces in China from 2015 to 2016. The developing actuality of Chinese large BFs has been quantitatively analyzed and the existing problems have been proposed clearly. Based on that, maintaining production stable, enhancing the quality of raw materials and improving the operation principles are suggested. Large BFs take advantages of high-quality hot metal, energy saving, cost-cutting, high mechanization and automation levels and are sufficient to meet the challenges of economic crisis, environmental pressure and security risk form the future. Thus, the number of large BFs in China will continue to increase in the future.
