摘要
针对树脂砂型离心铸管工艺中的覆砂均匀性问题，从理论上对砂层厚度均匀性与铸型结构间的关系加以分析，得出铸型承口端斜坡坡度存在临界值，并用试验结果证明了它的正确性。同时确定出，只要铸型斜坡坡度取２８℃左右，并对覆砂工艺适当加以控制，即可得到非常均匀的覆砂层。
Aimed at the evenness of sand layer coated on centrifugal casting mold the relationship between the evenness of sand layer thickness and mold structure has been analysed theoretically. There is a critical value of the slope of the socket of the mold and its correctness has been proved through testing results. It has been determined that so long as a slope of 28° or so and proper control of process of sand coated on the centrifugal casting mold hence evenness of the sand coated layer.
