oil quenching furnace

In materials science, quenching is the rapid cooling of a workpiece in water, oil, or air to obtain certain material properties. For oil quenching furnace, it contents the process of heating and quenching. For casting grinding balls, quenching process can be oil quenching for common high chrome balls, air quenching for super high chrome alloyed grinding balls; and for […]

Understand normalizing, annealing, quenching and tempering (3)

Quenching, a heat treatment process for metals and glass. Alloy products or glass heated to a certain temperature, and then in water, oil or air rapid cooling, generally used to improve the hardness and strength of the alloy. Commonly known as “dip fire. “. Heat treatment of metal cooled in air or water or oil […]

Understand normalizing, annealing, quenching and tempering-2

Quenching is the process of heat treatment to obtain the martensite structure by heating the metal or parts above the phase change temperature and then rapidly cooling them beyond the critical cooling rate. Quenching is to obtain the martensite structure, and after tempering, the workpiece to obtain good performance, in order to give full play […]

Understand normalizing, annealing, quenching and tempering-1

The microstructure obtained by high-temperature tempering is tempered sorbite. The main purpose of tempering is to eliminate quenching stress and get the required structure. According to the different tempering temperature, tempering can be divided into a low temperature, medium temperature, and high temperature. Tempered Martensite, troostite, and sorbite were obtained.

Study of the Hardening-toughening Heat Treatment Process of High Chrome Cast Iron Grinding Balls (2)

3.The graded austenitizing isothermal quenching process 3.1 Effect of grade austenitizing austempering on mechanical properties of Grinding Ball After the ball was austenitized at 980 °C for 150 min + 920 °C for 30 Min, and then put into a salt bath furnace at 260 °C for 30 min and 50 Min, the hardness and […]

Study of the Hardening-toughening Heat Treatment Process of High Chrome Cast Iron Grinding Balls (1)

Abstract: The influence of quenching-tempering heat treatment, conventional austempering heat treatment and multi-stage austenitizing austempering heat treatment on the microstructure and property of high chrome cast iron grinding balls were comparatively investigated. The results show that the impact toughness and impact fatigue resistance of the grinding balls are higher after austempering. The austempering heat treatment […]

Heat treatment process of the high chrome cast iron Grinding Media

Guo Zhi-hong, Wei Ying-hui, Wang Hong-wei (Taiyuan University of Technology, materials science, Taiyuan, Shanxi) ABSTRACT: A heat treatment process of high chromium cast iron grinding media with trace alloying elements Mo, V, NB was studied. The heat treatment processes of quenching at 980 °C, tempering at 400 °C and 600 °C was adopted. The microstructure […]
