The maintenance of sintering furnace

The maintenance of sintering furnace

1. The new furnace and lining refractories of replacement should be done after drying process. Oven to falling in to rise in stages. At the beginning of the dry, low temperature, long time, when the stove is cold by warming, furnace material of high moisture. In less than 400 degrees Celsius, to open the oven door discharge water vapor. When up to 700 ℃ heat preservation for a period of time. In order to make the temperature of the furnace body evenly.
, mesh belt furnace, the furnace temperature has risen to 400 ℃, shall run for a period of time, for oxidation treatment, improve the life of the net belt.
2. The low melting point impurity in the compact (S, Pb, zinc, etc) to the chamber of a stove or furnace material and heating elements are produces erosion, in order to improve the service life of the furnace, should be regularly purification furnace, presintering area, in particular, try to avoid in the powder metallurgy ingredients add S elements, such as to avoid pollution furnace and heating elements.
3. Regularly clean the stove, in using carbon monoxide or he carbon gases, could be breaking from the decomposition of hydrogen compounds to the carbon, this part of the carbon deposition on the furnace wall and heating elements, it will pollution stove, refractory erosion and damage the electric heating yuan
, so need to regular cleaning the stove.
4. Keep the body clean, regular cleaning furnace of iron oxide, gravel, zinc oxide and other debris.
5. Check the electric heating element and wire connection, prevent poor contact arc.
6. Due to the need of furnace operation under the low dew point, so the leak bolted flange sealed parts regularly
Detection.
7. Do not insert with grease tray in furnace, grease into Shanghai in one thousand will make a sharp increase in dew point affect normal operation.
8. The high temperature, don't play to open the door for a long time, in order to prevent the air into the furnace, damage the electric heating element.
9. No overtemperature operation.
