EXPERIMENTS WITH THE TECHNOLOGICAL PROCESS OF QUENCH COOLING THE STEEL GRINDING BALLS

One of the competitive advantages of ENERGOSTEEL Сompany is constantly consulting with specialized research institutes in our business activities. The topics of consultation are quite diverse: starting from the issues of the grinding media use in the grinding process to the introduction of new technologies in the grinding ball production.

In 2019, we conducted a joint work with one of the Kyiv Institutes under the National Academy of Sciences of Ukraine. This institute specializes in technical thermal physics. The purpose of the work is a comprehensive analysis of the hardening cooling process in the steel grinding balls production: the grinding balls initial temperature, the cooling medium composition, the water temperature and its mixing intensity, the method of controlling the cooling time and determining the quenching end in water emulsion and switching to self-tempering mode.

Upon the work done completion, there were been selected several variants the cooling media, which should improve the grinding balls hardenability, produced by experimental steel grades.

The check laboratory research results in industrial production conditions scheduled in the near future.
