Melting and casting rare earth alloy with water cold copper crucible 稀土及其合金熔铸&水冷铜坩埚感应炉
Their directional solidification is carried out by either Czochralski technology in the water-cooled copper crucibles or floating zone method without crucible, but the temperature gradient is not high with these two methods. 其定向凝固或者是在水冷铜坩埚内采用Czochralski技术进行,或者是采用不需要坩埚的悬浮区熔法实现,但这两种方法都不能得到较高的温度梯度。
A numerical model for simulating the temperature field of titanium melted in induction furnace with a water cooled copper crucible has been developed by using the direct finite difference method. 利用直接差分法,建立了水冷铜坩埚感应熔炼过程温度场数值模拟计算模型。
Cu_ ( 47) Ti_ ( 34) Zr_ ( 11) Ni_ 8 Bulk Amorphous Alloy Prepared by a Copper Suction Casting Method in Water Cooled Crucible 在水冷铜坩埚中用吸铸法制备Cu(47)Ti(34)Zr(11)Ni8块状非晶合金
Select water-cooled copper mold and graphite crucible as the reaction vessel, and set different welding current and duration of preparation. 氩弧熔化时分别选用水冷铜模和石墨坩埚做反应容器,设置不同的焊接电流和持续时间。
