Abstract (en)
Apparatus for steel hardening comprises a quenching region (8) wherein the quenching region surrounds a companion way of an elevator (5) in a quenching bath (2) and is separated from said quenching bath. The upper part of the quenching region is above the level of quenching fluid in the quenching bath, and an inlet for quenching fluid is provided at the lower part of the quenching region. Quenching fluid is supplied from below the steel part(s) to be hardened, which are dipped into said quenching region, and allowed to flow upwardly and overflow from the top of the quenching region into said quenching bath and thereby cool down the steel parts. <IMAGE>
