二硅化钼炉子的操作

1.炉子的干燥　Drying of the furnace
新砌筑或长期不用的炉子在使用前需要干燥。一般干燥温度为100-200℃，而元件长期在低瘟下使用将会引起低温氧化。小型炉子干燥时间短，几个小时对元件影响不大。大型炉子干燥时间长，需要注意。为了通风，最好将炉门打开，随着温度升高可以半开，到1000℃以上完全关闭炉门。
The new built frunace or the furnace that haven't been used for a long time should be dried before use.The drying temperature generally is 100-200℃. The elemnt that has been used for a long period time under low temperature will cause low-temperature oxidation. For the small-sized furnace，as its drying time is short， several hours will affect the element little， but for the large-sized one，as its drying is long. it should be dried carefully.You'd better open the furnace gate to make it ventilated. The gate may be half-ipened with the rising of temperature and fully closed when the temperature rises above 1000℃.

2.炉子的启动　Starting of the furnace
如果炉子干燥好了或不需要干燥就可以启动升温，为了避免过大电流冲击而使电器设备过荷，应采用下列步骤起动：
If the furnace has been dried or needn't to be dried，then it may be started to raise temperature. In order to avoid that it is impacted by over current and the electric device is overloaded， the following steps should be adapted:

3.元件的更换　Replacing of element
在操作过程中发现元件损坏应首先确定位置，同时准备好组合元件。然后将损坏的元件夹头导线与母线连结的螺丝松开，清理开陶瓷棉，连月穿砖一起拔出来，再将新组合元件从炉顶插入，连结好导线，堵好陶瓷棉即可升温。
If it is found that one element is damaged during iperating，firstly，you should determine where it is，at the same time prepare a made up one.Then loosen the thread which links the lead wire of the damaged element and the bus，clear out the ceramic cotton and pull out the through-brick.Afterward，insert the new wlwment from the furnace top，link the lead wire， block the gap with ceramic cotton and start raising temperature.
