我国的定向凝固技术研究工作起步较晚,尤其定向凝固的设备研究工作更尚属空白状态。为此我所在78年～80年首次研制成功我国第一台以液态锡为冷却介质的定向结晶炉。 该炉经测试及热分析表明:具有很大的温度梯度G(G=74.42℃/cm);具有较高的凝固速度R(R=56.58cm/小时);具有较小的糊状区宽度ΔZ(ΔZ=0.73cm)。这些主要参数已接近或达到70年代国外水平。我所在这台设备上进行了大量的定向凝固的研究工作并取得可喜
China’s directional solidification technology research started late, especially the directional solidification equipment research is still a blank state. To this end, I was 78 years to 80 years for the first time successfully developed China’s first liquid tin as the cooling medium oriented crystal furnace. The furnace was tested and the thermal analysis showed a large temperature gradient G (G = 74.42 ° C / cm), a higher solidification rate R (R = 56.58 cm / h), a smaller paste area width ΔZ (ΔZ = 0.73 cm). These main parameters have approached or reached the international level in the 1970s. I am doing a lot of research on directional solidification on this station and I am very pleased
