Embodiment Construction
[0015] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.
[0016] Such as figure 1 As shown, the improved holding furnace of the low-pressure casting machine of the present invention has two storage chambers: one is called the supply chamber 1; the other is called the filling chamber 2. The replenishment room 1 does not require strict sealing, it plays the role of storing and purifying the molten aluminum, it only needs to be well insulated, and liquid aluminum is added to this room in daily production. If the filling chamber 2 is fed with compressed air for product production, it must be fully sealed.
[0017] An immersion heater 3 is installed in the supply chamber 1 and the mold filling chamber 2, and is installed on the side of the furnace. The total power of the replenishment indoor heater is 30Kw. The total power of the filling indoor heater is 25Kw. The power of the heater in the supply room is sl...

The invention discloses an improved heat preserving furnace for low-pressure diecasting machines. The furnace is provided with a supply chamber 1 and a mold-filling chamber 2, wherein the liquid level of aluminum liquid in the supply chamber is higher than that in the mold-filling chamber, and a launder is arranged between the supply chamber and the mold-filling chamber. The insides of the supply chamber and the mold-filling chamber are respectively provided with an invasive heater 3, and the power of the heater of the supply chamber is greater than that of the mold-filling chamber. The improved heat preserving furnace disclosed by the invention has the advantages that because of adopting a two-chamber structure, the aluminum liquid in the supply chamber can be purified to a certain degree in the process of operating, thereby improving the quality of the aluminum liquid; the heaters are soaked in the aluminum liquid in the process of operating, thereby improving the thermal efficiency and reducing the energy consumption; and the surface of the aluminum liquid has no radiation heat conduction, thereby reducing the oxidation of the surface of the aluminium liquid, and reducing the useless consumption of the aluminum liquid.
Description
technical field [0001] The invention relates to an industrial furnace, in particular to a holding furnace used for a wheel low-pressure casting machine. Background technique [0002] At present, the general-purpose low-pressure casting machine holding furnace is generally a one-room, radiant silicon carbide rod heating. The furnace chamber is not only used as a liquid aluminum storage chamber, but also as a heating chamber and a pressurized chamber. The silicon carbide rod is heated, and the heat passes through radiation and air conduction to ensure a constant temperature of the molten aluminum in the furnace. This kind of holding furnace plays a key role in the application process of low pressure casting machine. However, with the development requirements of casting technology, some existing problems and shortcomings are gradually emerging. First, when adding molten aluminum, the heating power supply must be cut off to stop production, which affects the continuity of pro...
