The data on iron and steel production worldwide in 2015 and 2016 are presented. It is shown that more than 75% of iron ore part of charge materials for blast furnaces are presented by sinter. Operation experience of Russian and Chinese blast furnaces are comparatively analyzed. It is displayed that lowering of charge of sinter fine fraction can be considered as one of the main directions for improvement of operation parameters of blast furnaces in our country. The paper examines the example of successful im plementation of innovative screens developed by Research and Engineering Corporation “Mekhanobr Tekhnika” and put into operation at Magnitogorsk Iron and Steel Works. This example has been used as the base for development and put into commercial practice the wide dimension range of new screens.
