摘　　要：随着铁路转向架的不断改进与发展 ,要求摇枕、侧架必须具有较好的内外品质、毛坯尺寸精度 ,以及具有较佳的综合力学性能 ,尤其是疲劳性能。现在生产应用的水玻璃砂工艺 ,由于存在很多工艺缺陷 ,对酯硬化水玻璃砂、酯硬化碱性酚醛树脂砂、CO2 硬化碱性酚醛树脂砂等进行试验研究 ,分析影响因素 ,进行工艺类比 。With the improvement and development of steering frame used for railroad that requires scale and side-frame to be preferable quality inside and outside, size precesion of roughness and general mechanic properties, espelially the fatigue property. Now Sodium silicate-bonded sand process in production, which study on the ester cured sodium silicate sand, ester cured alkaline phenolic resin sand and CO_2 Cured alkaline phenolic resin sand as their many process defects, and analyzing the influncing elements, having process analogy and offering the process referrence.
