Kouman yo itilize muffle founo kòrèkteman

1. When the muffle furnace is used for the first time or used again after a long period of inactivity, it must be oven-dried. The oven time should be four hours at room temperature 200°C. 200°C to 600°C for four hours. When in use, the maximum furnace temperature must not exceed the rated temperature, so as not to burn the heating element. It is forbidden to pour various liquids and easily soluble metals into the furnace. The muffle furnace is best to work below the maximum temperature of 50 ℃, when the furnace wire has a longer life.

2. Founo a mòf ak kontwolè dwe travay nan yon plas kote imidite relatif la pa depase 85%, epi pa gen okenn pousyè kondiktif, gaz eksplozif oswa gaz korozivite. Lè materyèl metal la ak grès oswa renmen an bezwen chofe, yon gwo kantite gaz temèt pral afekte ak korode sifas la nan eleman chofaj elektrik la, sa ki lakòz li yo dwe detwi ak diminye lavi a. Se poutèt sa, chofaj la ta dwe anpeche nan tan ak veso a ta dwe sele oswa byen louvri yo retire li.

3, kontwolè founo mòf lan ta dwe limite pou itilize nan seri tanperati anbyen 0-40 ℃.

4. Dapre kondisyon teknik yo, tcheke regilyèman si wi ou non fil elektrik gwo founo dife a ak kontwolè a nan bon kondisyon, si pwent endikatè a kole oswa stagnation lè w ap deplase, epi sèvi ak potansyomètr la pou kalibre mèt la akòz asye mayetik. , demagnetization, ekspansyon fil, ak shrapnel Ogmantasyon erè ki te koze pa fatig, echèk balans, elatriye.

5. Pa rale tèrmokapteur a toudenkou nan tanperati ki wo pou anpeche jakèt la pete.

6. Toujou kenbe fou a mouf pwòp epi retire oksid nan fou a nan tan.
