Enormous economic and social benefits were produced through establishing the production mode of circular economy, strengthening the control of blending yard and optimizing sinter burden proportion.

The quality improvement of sinter ore is the basic measures for BF smelting and high efficiency. Methods were presented to improve the basicity according to the different ore burden.

The softing, melting and dropping temperatures of Baima sinter were lower, which is beneficial to improve permeability of the burden in blast furnace.
