Comparison of Industrial Quenching Oils

This article is a response to the state of art in monitoring cooling capacity quenching oils industrial practice. Very often, hardening shop requires report with data on process for particular oil. However, interpretation can be rather difficult. The main goal our work was compare various criteria used evaluating oils. Those which prove essential operation tempering plants would then introduced into Furthermore, describes changes properties oil shop, effects temperature its and impact water content certain parameters selected Cooling curves were measured (including rates time reach relevant temperatures) according ISO 9950. power area below rate curve as function (amount heat removed nose region Continuous transformation - CCT curve) calculated. V-values based Tamura, reflecting steel type curve, calculated well. All compared against hardness microstructure section through cylinder made EN C35 cooled Based results, are recommended assessing suitability specific grade product size. experiment Houghto Quench C120, Paramo TK 22, 46, CS Noro MO 46 Durixol W72.
