Production and Application of the Austenitic High Chrome Cast Iron Grinding Ball (1)

Zhang Bao-jie , QIAO Xiao2ai , Liu Wen-hui ( Shanxi Linfen Mechanical Casting Factory , Linfen 041000 , China) Abstract :This article mainly introduces production and applction of the high chrome cast iron austenitic grinding ball. For obtaining austenite in casting state , the balls have stronger impact toughness. In addition, martensite transformation happens under impact wear […]

Improvement and optimization of gating system for metal mold ball production line (2)

New automatic gating system control method: 1) The intermediate frequency holding furnace is tilting to obtain the Tundish’s total weight, and the molten metal poured into the Tundish. The Tundish is connected between the mold for processing the casting molding on the automatic pouring production line and the gating system of the intermediate frequency holding […]
