平尺的要求并不高,大部分表面不需要加工。但是由于铸件长、重量大(1200公斤)、断面又厚(200×80公厘),因此用潮型来铸造,在技术上的控制是比较困难的。当铸造车间接到四公尺长平尺的铸造任务以后,大家都认为只有用干型才行,当时我厂苏联专家建议采用潮型铸造。最初,用潮型试做了两个,未能得到成功。后由苏联专家指导,指出了在操作过程中的缺点,改进了办法,终于得到了成功。
Flat-foot requirements are not high, most of the surface does not require processing. However, due to the long casting, heavy weight (1200 kg), thick section (200 × 80 mm), so with the tide-type casting, the technical control is more difficult. When the foundry received a casting job of four meters long flat ruler, we all thought it was only possible to use a dry type. At that time, Soviet Union experts in our factory proposed the use of tide casting. Initially, the tide-type test done two, failed to be successful. After the guidance of the Soviet experts, pointed out the shortcomings in the operation process, improved methods, finally succeeded.
