Characteristic features of the heat treatment of lengthy steel components in the bolling layer

Use of a pseudo-liquefied layer as an ecologically safe cooling medium

“…For example, in quenching articles 400 mm long and 36 mm in diameter in oil the warping (bending of the axis) is 0.8-1.1 mm, whereas in a boiling layer it is less than 0.3 mm (for vertical submersion in austenitization and quenching). Similar results were obtained in [4] in quenching loom spindles in a boiling layer. 2).…”
