Fluidized bed for quenching steel wire and process thereof

摘要

A fluidized bed is disclosed for the continuous quenching of steel wires. The fluidized bed is provided with an air convection cooler with high cooling capacity. The temperature of the fluidized bed is regulated by means of a cooling air flow. Such a bed is applicable in the patenting operation, in which the carrying gas for a fluidized bed is taken from the exhaust gases of the austenitizing furnace.
