What You Need to Know to Operate Vacuum Furnaces
The environment needed for the vacuum furnace is different from what is commonly seen in “conventional” treatment departments. First, the environment needs to be “clean”. Operators should wear white gloves and clean clothes.Vacuum-treated pieces should not be handled without such protection.
Pieces handled by a gloveless hand will have an imprint that would immediately create a rust stain. Pieces are then packed in plastic envelopes, filled with nitrogen, and sealed.
The operators play a key role in the loading-unloading and start-up phases of the cycle, and the cycle should not be assisted. During the loading phase, the operators need to check that the inside of the furnace has no breakages or deposits, introduce the load with due caution to prevent damage, and do the same during unloading.
Checks are already introduced automatically for the plant’s seal, and they have to be conducted during the start-up phase. During alarms, operators need to understand whether the problem allows the alarm to be silenced or not, and if necessary, ask for assistance.
The plant can be guaranteed for years. The vacuum can only offer protection against wear and not when human preparation is lacking.
For decades, the industry has been using heating processes in vacuum as they provide many benefits that enable high-quality products to be obtained through special applications.
