| Abstract: | The mineral oil based quenchants are being universally used up till the present moment. The quenching performance and the service life of the mineral oil based quenchants can be improved on by hydrotreating to remove sulfur, nitrogen, oxygen and some metal elements from them. The cooling characteristics of the mineral oil based quenchants are related to such factors as temperature ranges of film boiling stage, nuclear boiling stage and convection stage during the quenching, additives and so on. The basis of choosing mineral oil based quenchants were indicated, including flash-point conforming with the requirements, lower tendency to produce sludge, not corroding workpiece, desirable heat transfer performance and so forth. The degradation process and the detections of moisture, neutralization number, saponification number, ash content, conradson carbon residue, sludge, density and other indexes of mineral oil based quenchants were briefly described. |
