Method of buffering modulating wave melting aluminum furnace

Method of buffering modulating wave melting aluminum furnace

The buffer modulated wave aluminum melting furnace must be baked before use. For the buffer modulated wave aluminum melting furnace that has just been lined, it should be naturally dried in the air at not less than 10-15°C for 2 to 3 days before being energized.

The oven process is as follows (see crucible maintenance process for details):

A. The room temperature rises to 100°C, the heating current is 15A, the empty pot is heated to 100°C without a lid, and the temperature is constant for 2h;

B. Haroratni 100 ℃ dan 200 ℃ gacha ko’taring, isitish oqimi 20 A, bo’sh idish qopqoqsiz 200 ℃ ga qadar isitiladi va harorat 2 soat davomida doimiy bo’ladi;

C. 200 ℃ dan 300 ℃ gacha ko’taring, isitish oqimi 30 A, bo’sh tigel qopqoqsiz 300 ℃ gacha isitiladi, 1 soat davomida doimiy harorat;

D. Haroratni 300 ° C dan 800 ° C gacha ko’taring, to’liq yuk bilan qizdiring, bo’sh tigelni yoping va 800 ° S ga qadar qizdiring, haroratni 1 soat davomida doimiy ushlab turing;

When the buffer modulated wave aluminum melting furnace is put aside for a long time and then used again, the furnace should also be baked in accordance with the above regulations.
