Technological progress and development of pellet by adding steelmaking sludge

This paper briefly presents a process concept of the disposal of steelmaking sludge,which is simple,steady, reliable and easy to operate.

WT5BZ]The bench test and plant test of pelletizing with addition of steelmaking sludge were conducted under the operational condition of Jinan I&S Co.

The sintering dust was mixed with steel-making sludge, and then the slurry was sprayed upon burnt lime for lime slaking in TANGGANG 210 m2 sintering plant.

Produces in the high furnace ball group matches adds thesteel making to violate the law the dust removal ash,in agglutinatesin the production to match adds the steel-making sludge,cokes dryly extinguishes the burnt dust removal ash,oxidizes the iron sheet,thesteel slag and so on,has substituted the massive powdered ore,reduced the powdered ore consumption,has th.

In order to decrease pollution of the environment,utilize rationally steelmaking mud and reduce productive cost of pellet,the industrial experiment adding steelmaking mud to pellet is made in 10m 2 vertical furnace of Ji-steel.

Adding steelmaking mud can recover useful metal in steelmaking mud and can increase pelletizing propertis in the production process of pelletizing This method can implement the aim of comprehensive utilization The thickness of steelmaking mud slurry can be controlled by determining specific gravity metho

The theoretical analysis proved that steelmaking dust and mud is a valuable resource.
