发现流动性随浇注温度的升高呈非线性增长
最大增幅达16.5 mm/℃。
Abstract
A new apparatus was designed to improve the accuracy and reproducibility of alloy fluidity tested by spiral sample in the sand mould. Through automatic casting mechanism controlled by single-chip-microcomputer
the molten alloy is poured into the spirals at a scheduled temperature and constant pressure head. By the experimental analysis and comparing with the tranditional apparatus
the new apparatus show a great improvement in accuracy and reproducibility. The effects of pouring temperature on fluidity of aluminum alloys have been tested by the new improved apparatus
obtaining the relationship between fluidity and pouring temperature.
