Embodiment Construction

[0017] Structure: As shown in the figure: the liquid-feeding chamber 1 and the pressurizing chamber 2 with the lining layer 3 constitute the holding furnace body.

[0018] There is a liquid feeding slag outlet 1.1 on the upper part of the liquid adding chamber, and a thermocouple 1.3 and an L-shaped degassing rod 1.4 are installed in the liquid adding chamber. A liquid adding chamber heater 1.7 is installed on the lower part of the liquid adding chamber. There is a liquid inlet pipe 1.5, and a flow control valve 1.6 is installed on the liquid inlet pipe. The flow control valve rod is connected and driven with the control motor 1.2 installed on the upper part of the liquid feeding chamber. The liquid inlet pipe passes through the liquid feeding chamber and the liquid feeding pipe 1.8 The next wall of the pressurized chamber is also provided with a liquid outlet 1.9.

Abstract

The invention provides a double-room heat preservation furnace for low-pressure continuous casting and an operation method. A liquid adding room with an inner liner layer and a pressurizing room form a double-room heat preservation furnace body. Aluminum liquid is injected into the pressurizing room through the liquid adding room. Under a pressurizing condition, the aluminum liquid is provided for casting through a liquid rising pipe. The effect of integration of an aluminum liquid injection function, heating and heat preservation functions, a degassing function and an aluminum liquid automatic compensating function is achieved, and the double-room heat preservation furnace is suitable for being used as a heat preservation furnace for aluminum alloy wheel low-pressure continuous casting.

Description

technical field [0001] The invention proposes a double-chamber holding furnace for low-pressure continuous casting and an operation method in the field of metal casting. Background technique [0002] The holding furnace is a necessary special equipment for the aluminum wheel casting process. The traditional discontinuous low-pressure casting process uses a single-chamber holding furnace. During the wheel casting process, when the aluminum liquid in the holding furnace is insufficient, it is necessary to suspend the wheel forming casting process. , depressurize and fill the holding furnace with aluminum liquid, and then continue the casting operation of wheel forming. [0003] When the above-mentioned equipment is filled with aluminum liquid, it is necessary to stop injecting aluminum liquid into the wheel forming mold and release the pressure of the holding furnace, which cannot meet the needs of the wheel continuous casting process, and has high power consumption and low ef...
