Abstract:

The paper discusses new approaches for eliminating sporadic, non-uniform film boiling processes during batch quenching of steel parts and causing part excessive distortion and cracking. The film boiling process is common for batch quenching when parts are usually placed close to each other. Narrow spacing between the parts results in a high hydraulic resistance preventing an adequate flow of quenchant even when powerful propellers are used. Two alternative ways to improve quenchant agitation are considered in the paper: hydrodynamic emitters and electrolytes as a quenchant while negatively charging the steel parts being quenched. The paper also considers new quenching technologies based on a) the proper control of the nucleate boiling process parameters using a universal correlation obtained by the author, and b) the use of low concentration solutions of polymers of inverse solubility in water.
