Heat Treatment of Ruston Bucyru RB38 Top Roller
1 Quenching and Tempering
We first pretreat raw blanks via cutting and forming, then polish them to eliminate surface burrs. Next, we perform non-destructive testing to check for internal flaws including cracks and pores. Workers put the top roller into a heat treatment furnace, heat it to the steel’s austenitizing temperature and keep steady holding time to secure even metallographic structure across the whole component. After heat preservation, the workpiece is fully immersed in water for rapid cooling. Its internal structure transforms into martensite to achieve high overall hardness.
2 Surface Quenching
We finish the full quenching and tempering procedure first, then conduct separate surface quenching on the wheel’s track contact surface. This process creates a durable wear-resistant outer layer, significantly boosting the wheel’s abrasion resistance and lengthening its service lifespan.
