Badschie Sthal Engineering,
Germany is a leading consulting companies in Europe, offering
consultation on temperature controlled processing of wire rod and bar
products. Together with BSL, Germany, PP Rolling Mill has developed
patented quenching nozzles that have an extremely high heat transfer
coefficient achieved by laminar and turbulent flow within the nozzle.
Principle of Operation : Large
quantities of water at low pressure and high kinetic energy impact the
hot bar in the primary cooling chamber. The high kinetic energy
disrupts the steam jacket formation to allow immediate cooling,
bypassing the inefficient film boiling. Inside the nozzle, the
precisely positioned secondary cooling chambers reintroduce turbulence
to prevent steam blanket formation for continued intense cooling.
Application :
- Inter-stand cooling
- Wire rod mill water boxes
- Post-rolling quenching (for self tempered rebar)
