At the beginning of the filtration operation, filtration including the filtration tube 12 was performed.
It is necessary to preheat the entire room 2
Injection of hot molten metal causes damage due to uneven expansion
There is fear. For this reason, when starting the operation, the heater 15 is energized without pouring the molten metal, and the filtration chamber 2 is cooked empty.
The filter tube 12 is heated, but only the air-conditioning with the heater 15 energized is made of ceramic porous material and has a very high adiabatic coefficient.
Not heated so I think inside and lower side of the stomach filtration tube 12, to raise the temperature to about 600 ° C., 34 hours required significantly delayed the start of filtration time. Therefore, the present invention
A communication hole 16 is opened in the lid 14 by shortening the time required for raising the temperature inside and on the lower surface of the filtration tube 12.
Is connected to a blower pipe 19 having a heater 17 and a fan 18.

(Overall operation) When a molten metal such as aluminum is supplied from the inlet 3 to enter the degassing chamber 1 and the stirring blade 7 is rotated by the motor 8 while being heated by the heater 5, the inert gas in the molten metal is removed. The air bubbles are dispersed and combined with the floating gas and nonmetallic inclusion particles in the molten metal, rise, and accumulate at one corner of the upper surface of the degassing chamber 1.
Deposits are removed by any suitable means. It degassed soluble hot water,
Hot water enters the filtration chamber 2 through the communication hole 4, is filtered and purified by the filtration tube 12, and flows out of the hot water outlet 13 .

After that , supply electricity to the heater 15 without adding molten metal and filter.
The chamber 2 was cooked empty, heating the filtered tube 12, but only cooked empty heater 15 energized, the cross-sectional ceramic porous Ltd.
The inside and underside of the filtration tube 12, which has a very high heat count, did not rise as expected, and it took 34 hours to raise the temperature to about 600 ° C.

And a heating time on the lower surface side was shortened. A communication hole 16 was opened in the lid 14, and a blower pipe 19 having a heating tool 17 and a fan 18 was connected to the communication hole 16 and heated by the heating tool 17. The hot air is blown into the filtration chamber 2 by the fan 18 and is sent into the filtration chamber 2 through the communication hole 16.
The filtered hot air spreads to every corner of the filtration chamber 2
2 can be preheated uniformly, and hot air can be
Through the outlet 12 (and the entrance 3).
So that the inside of the filtration tube 12 is also uniform
It can be preheated, and the inside and lower side of the filtration tube 12 can be heated up to about 600C in about 20 hours, and the filtration start time can be reduced by 14 hours.

In other words, the filter tube is heated by supplying electricity to the heater for heating the molten metal attached to the lower surface of the lid without putting the molten metal, and the filter tube is heated. The inside and the lower side of the heater do not heat up as desired. To raise the temperature, about 6
It is necessary to raise the temperature to 00 ° C.
Time is required and filtration start time is significantly delayed.
