在分析工作中,经常使用高温熔融方法分解试样。过去我们一般采用酒精喷灯或马弗炉熔融,但前者耗费大量酒精,不利于大批操作,后者操作不便,常因熔融过程中溅溢出熔剂而损坏炉膛及硅碳棒等。我们学习了我公司515队化验室的经验,自己安装了一种更为简易实用的硅碳棒熔融炉。通过几年生产实践,感到它具有升温快、温度高、操作时便于观察 In the analysis work, high temperature melting method is often used to decompose the sample. In the past we generally use alcohol burner or muffle furnace melting, but the former consumes a lot of alcohol, is not conducive to a large number of operations, the latter inconvenient to operate, often due to melting process spilled flux and damage the furnace and silicon carbide rods. We learned the experience of our company’s 515 team laboratories and installed a more simple and practical silicon carbide rod melting furnace. Through several years of production practice, I feel it has fast heating, high temperature, easy to observe the operation
