Segmented Nozzle Fields
High convective effectiveness with locally adjustable quenching zones via activatable and deactivatable nozzle sections.
WSP Advanced Convection Quench (ACQ) as an Alternative to Lead Bath Cooling
WSP supplies heat treatment and tempering lines for the hardening of carbon steel strip using hydrogen quenching based on the specially developed WSP Advanced Convection Quench (ACQ). Hydrogen as a cooling medium has been used in heat treatment for decades. The technological distinction of the WSP solution does not lie in the medium itself, but in the controlled convective impingement of the strip, replacing classical molten metal bath technologies such as lead baths.
Request Technical InformationWSP ACQ System Features
The WSP ACQ system is based on a specifically designed nozzle and flow geometry for intensive convective cooling of steel strip. The development objective was not a laboratory-optimized maximum cooling rate, but an industrially controllable quenching system with defined and adjustable heat transfer characteristics.
Flexible Operation Modes
Suitable for single-strip and multi-strip operation with stable performance under continuous industrial conditions.
Adjustable Heat Transfer
Wide adjustable range of heat transfer coefficients for adaptation to different carbon steels, strip geometries and throughput requirements.
Industrial References & Specifications
The WSP ACQ system is in operation in several industrial applications since 2017. The systems are operated by leading strip steel producers and cover a wide range of product and throughput requirements.
