Excavators are heavy machinery equipment used in construction and mining works. The bucket teeth at the tip of the bucket excavator are used for excavation work. They are easily damaged by direct contact with the medium. One of the materials used in bucket tooth excavators is mild steel with a carbon content between 0.33%-0.5%. However, the hardness value of this material does not yet meet the standards of bucket tooth excavators, so the optimum hardness value for its heat treatment should be known. In addition to this, its tensile strength, impact strength and microstructure in optimum condition will also be known. The optimization method was carried out by Taguchi experimental design with L9 orthogonal and ANOVA (analysis of variance). The factors or parameters in this study are heating temperature, holding time, quenching medium and tempering temperature. In this experiment, nine mild steel samples were tested with different heating temperatures (850oC, 875oC, 900oC), different holding times (60, 90 and 120 minutes), and different quenching media (oil, water and brine) , and different tempering temperatures (250oC, 450oC, 650oC). The calculation and verification experiments by Taguchi method show that the optimum hardness parameters are heating temperature 875℃, holding time 60 minutes, water quenching medium, and tempering temperature 250℃. At the same time, the variance analysis shows that four factors have influence on the hardness of bucket tooth excavator.

Because XTPtrack company established a department, this department mainly tests the influence of various temperatures, time, etc. on the bucket teeth, debugs the best standard, and ensures the hardness and quality of each excavator bucket tooth, so as to provide customers with for better quality products.
