垂熔

一种用于垂熔机的可编程电流控制器

A Programmable Current Controller Used for Incipient Fusion Machine

低La含量时，La2O3粒子弥散分布，垂熔性能好。

However , when La content is lower , the La_2O_3 particles are distributed dispersively , creating good bars with fine and homogeneous grain .

1000kW真空垂熔烧结炉的研制

Development of 1000 kW vacuum vertical sinter furnace

试验发现：垂熔烧结可获得较低杂质含量的合金坯料，活化烧结和中频感应烧结获得的坯料杂质含量较高。

Experiment was discovered : the impurity of the alloy billet produced by direct resistance sintering was lower , than by activated sintering and medium-frequency induction sintering .

在合理的升温制度下，最终得到的铈钨烧结坯的密度达到了17.8g/cm~3，与垂熔烧结方法的水平相当。

Under proper heating-up system , the density of cerium-tungsten pieces after sintering reached 17.8g / cm ~ 3 , it can compare with the level of other sintering technique .

垂熔过程中一旦发生断条，系统可自动关闭主电路，给出所条故障报警信号。

Once the molybdenum bar breaks in vertical sintering process , the system can switch off the main circuit automatically , reset the control circuit , and put forward warning signal of breaking bar fault .
