Description

Inlet dephosphorization device of finishing mill

Technical Field

The application relates to the field of steel production equipment, in particular to an inlet dephosphorization device of a finishing mill.

Background

The steel is oxidized at high temperature to form a layer of compact iron scale on the surface. If the scale cannot be removed before rolling, the scale can be pressed into the surface of the steel strip by the rollers during rolling, and the surface quality of the steel strip is affected. The remaining scale also accelerates wear of the roll and reduces the service life of the roll, and therefore, the scale must be removed from the surface of the billet prior to rolling.

The method for removing the iron oxide scale by using the mechanical impact force of high-pressure water is one of the currently available and effective methods. In the dephosphorization system, high-pressure water generated by a high-pressure water pump enters a dephosphorization nozzle. Under the action of the nozzle, the high-pressure water forms a fan-shaped water beam with large impact force and is sprayed to the surface of the steel billet.
