The invention relates to a molten aluminum heat preserving furnace for high-pressure casting. A furnace chamber formed by a quiescent chamber and a liquid taking chamber is arranged in a furnace body on a furnace body support, a ceramic filtering piece is arranged between the quiescent chamber and the liquid taking chamber, a lining layer, a heat preserving layer and a furnace body outer shell are arranged in the furnace chamber, an upper cover is arranged on the furnace body through a sealing strip groove and a sealing strip, an end sealing body is arranged on one side of the furnace body through an O-shaped sealing ring, a molten aluminum filling port is arranged on one side of the furnace body, and the furnace body is closed through a quick connection device on the left side. A thermocouple-protection tube, a silicon carbide rod protection tube, a liquid taking port and a liquid taking port cover are arranged on the furnace body, and a liquid taking chamber molten aluminum temperature detection hole, a furnace gas temperature detection hole and a quiescent chamber molten aluminum temperature detection hole are also formed in the furnace body. According to the molten aluminum heat preserving furnace for high-pressure casting, due to the fact that heating tubes and the heat-preserving layer are arranged in the furnace body and ceramic is used as the inner layer of the furnace body, the purposes of complementing cooling of molten aluminum, keeping temperature constant and preventing the temperature from falling can be achieved; in addition, due to the fact that the ceramic is used as the lining layer, the molten aluminum heat preserving furnace for high-pressure casting is heatproof and does not adhere to the molten aluminum.
Description
technical field [0001] The invention relates to facilities for metallurgical casting, in particular to a molten aluminum holding furnace for high-pressure casting. Background technique [0002] After the molten aluminum is melted, it needs to be still to exhaust air and eliminate scum and sediment. However, due to the high temperature of the molten aluminum, it is easy to cool down or even solidify during the static process, resulting in the failure of normal pouring. Contents of the invention [0003] In order to realize the static heat preservation of molten aluminum, the invention proposes a liquid aluminum heat preservation furnace for high pressure casting. The holding furnace is equipped with a static chamber and a liquid-taking chamber in the furnace body with a lining and an insulation layer, and a ceramic filter is installed between the two, and a silicon carbide rod heating tube and corresponding detection holes and silicon carbon rods are installed in the furnac...
