SECO/WARWICK, after commissioning several units and implementing significant improvements to the design, registered its drop-bottom furnaces under the name VertiQuench®. The name describes the process of very fast vertical quenching. The heat-treated material is dropped into the quenching tank placed directly under the furnace. This furnace provides AMS 2750-compliant quench transfer times; tight temperature uniformity; low energy consumption; compact design, which enables line expansion; and fast and full load immersion up to five seconds.
