二硅化鉬爐子的操作Operation of MoSiz furnace

1.爐子的干燥Drying of the furnace

新砌筑或長(zhǎng)期不用的爐子在使用前需要干燥。一般干燥溫度為100-200℃，而元件長(zhǎng)期在低溫下使用將會(huì)引起低溫氧化。小型爐子干燥時(shí)間短，幾個(gè)小時(shí)對(duì)元件影響不大。大型爐子干燥時(shí)間長(zhǎng)，需要注意。為了通風(fēng)，最好將爐門(mén)打開(kāi)，隨著溫度升高可以半開(kāi)，到1000℃以上完全關(guān)閉爐門(mén)。

The new built furnace or the furnace that haven’t been used for a long time should be driedbefore operation. The drying temperature generally is 100-200℃. The element that has been used for a long period 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-opened with therising of temperature and fully closed when the temperature rises above 1000℃.

2.爐子的啟動(dòng)Starting of the furnace

如果爐子干燥好了或不需要干燥就可以啟動(dòng)升溫，為了避免過(guò)大電流沖擊而使電器設(shè)備過(guò)荷，應(yīng)采用下列步驟起動(dòng)：

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.元件的更換Re3placing of element

在操作過(guò)程中發(fā)現(xiàn)元件損壞應(yīng)首先確定位置，同時(shí)準(zhǔn)備好組合元件。然后將損壞的元件夾頭導(dǎo)線與母線連接的螺絲松開(kāi)，清理開(kāi)陶瓷棉，連用穿磚一起拔出來(lái)，再將新組合元件從爐頂插入，連接好導(dǎo)線，堵好陶瓷棉即可升溫。

If it is found that one element is damaged during operating, 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 element from the furnace top, link the lead wire, block the gap with ceramic cotton and start to raise temperaturenull
