Heat treatment process of the high chrome cast iron Grinding Media

April 24, 2019/in Grinding media balls, Heat Treatment Process /by Sara Wu

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 […]

Development of high carbon chromium GCr15 grinding ball with high wear resistance

April 19, 2019/in Grinding media balls /by Sara Wu

Introduction As a kind of grinding body, grinding ball requires high hardness, the higher the hardness, the better the wear resistance. From the carbon content of the grinding ball: With the increase of carbon content of the grinding ball, the higher the hardness of the grinding ball, the greater the wear resistance, when the carbon […]

POINTS IN SOLIDIFICATION PROCESS OF GRAY CAST IRON AND NODULAR CAST IRON (6)

April 11, 2019/in Castings /by Sara Wu

EUTECTIC TRANSFORMATION OF NODULAR CAST IRON The eutectic transformation of spheroidal graphite cast iron is not as obvious as that of gray iron, although graphite is first precipitated and austenite is then precipitated, graphite plays a less dominant role in the Eutectic Solidification process coexisting and coexisting under conditions of common and liquid contact.

SOLIDIFICATION PROCESS OF GRAY CAST IRON AND NODULAR CAST IRON (5)

April 9, 2019/in Uncategorized /by Sara Wu

Third. 3. EUTECTIC TRANSFORMATION AND NUCLEATION OF CAST IRON Both gray cast iron and ductile iron are EUTECTIC FE-C alloys, and eutectic transformation is the most important step in the solidification process. Although primary austenite is precipitated in hypoeutectic cast iron, eutectic cast iron, and hypereutectic cast iron, however, the eutectic transformation does not rely […]

KEY POINTS IN SOLIDIFICATION PROCESS OF GRAY CAST IRON AND NODULAR CAST IRON (4)

March 28, 2019/in Castings /by Sara Wu

Morphology of primary AUSTENITE DENDRITE The Crystal Lattice of austenite is face-centered cubic. When the AUSTENITE is nucleated and grown directly from the liquid iron, the AUSTENITE is stable only when the surface energy is minimum and octahedral crystal is formed. Then, because the concentration gradient of solute in the liquid iron at the edge […]
