十米水位台上有一套测量联通管水位的标尺,它是该设备精度的保障基准,其精度越高,则设备精度越可靠。在研制该套标尺过程中,我们抓住了以下几点关键性问题。 1.材料的选用目前国内生产的膨胀合金4J36、4J32,线膨胀系数为1.2～1.8×10~(-6)/℃。虽为普通钢的1/6～1/10,但制造标尺仍不太理想。经与重庆精密合金研究所合作,专门配制冶炼了CO54rg高级铟瓦合
Ten meters of water on the stage there is a measure of the water level of the Unicom pipe ruler, it is the protection of the accuracy of the equipment benchmark, the higher the accuracy, the more reliable equipment accuracy. In developing the set of rulers, we have grasped the following key issues. 1. Selection of materials At present, the domestic production of expanded alloys 4J36, 4J32, linear expansion coefficient of 1.2 ~ 1.8 × 10 -6 / ℃. Although the general steel 1/6 ~ 1/10, but the manufacturing scale is still not very satisfactory. After cooperation with the Chongqing Institute of Precision Alloy, specially formulated smelting CO54rg Advanced Indium Tile
