Through modifying the screw feeder for furnt lime addition , puting the plow plates on the sinter-mix conveyer and replacing clean water by BOF slurry as added water for primary mixing,the sinter output of №2 sintering plant in XIANGGANG was increased and the plant environment was improve

Phosphorus removal of waste water by using converter sludge*;

A cheap desulphurizer for converter sludge can remove over 90% hydrogen sulphide in the first stage and TG series high-efficiency molding desulphurizers are used in the second stage.

After transformation, converter sludge has been totally recovered and the dedusting sewage is utilized circularly, which have achieved satisfactory economic benefit and enviroment benefit.

A method to recycle BOF sludge water by using it as the palletizing water added in drum mixer in sintering plant was introduced in this paper.

Technology on utilization of OG sludge at MaSteel;

Process of OG sludge recovery with production of cold-hardened pellets is introduced.

The converter OG sludge treatment way in China and using it to sintering in Magang are introduced.

With paying more attention to protection of resources and environment in recent years, better utilizing BOF sludge has become an urgent task for China's steel companies.

The property of BOF sludge and the influence of adding BOF sludge by dry/wet process on mix granulation and sintering process indices were studied Based on the experimental results,the comprehensive method utilizing BOF sludge by dry/wet process was adopted in XIANGGANG sintering plant and the satisfactory effect was obtained.
