Casting equipment

Abstract

The invention relates to aluminum alloy refining and casting integrated equipment. Two chambers are designed in a heat preservation furnace, and are a molten aluminum adding refining chamber and a pressurizing casting chamber respectively, after molten aluminum is refined in the molten aluminum adding refining chamber, the molten aluminum cannot be in contact with air, reoxidation of the molten aluminum is avoided, and castings with the good quality can be manufactured. Meanwhile, dipping type electric heating is adopted by the heat preservation furnace, the heating efficiency and the uniformity of the molten aluminum temperature are improved, after pressure casting, the high-temperature inert gas cannot be directly discharged into the atmosphere and is discharged into a gas storage tank for purification, then the gas is reused, and the utilization rate of resources and energy is improved.

Description

technical field [0001] The invention relates to an aluminum alloy refining casting forming equipment. Background technique [0002] The embryonic form of the low-pressure casting method can be traced back to the beginning of the last century. It was proposed in France in 1917 and in Germany in 1924 for aluminum alloy, but it did not form a large-scale industrial production. Production for commercial purposes began in 1945 after World War II. In 1958, Zeneramotas of the United States used a large number of aluminum alloy castings on the engine parts of small cars, and adopted a low-pressure casting method. The low-pressure casting method was introduced into my country around 1957, but it really attracted the attention of the industry, and it was around 1960 that various researches and equipment were introduced. However, this epoch-making process, which broke the common sense in the past, has almost no riser, and has a completely different difficulty compared with the gravi...

Problems solved by technology

In this method, the temperature of the molten aluminum is not uniform due to the radiation heating of the upper heating rod, and the temperature of the upper part is higher than that of the lower part; after the aluminum liquid is refined, it will be oxidized and absorbed during the transfer process, which will weaken the refining effect; the temperature of the aluminum liquid entering the holding furnace is normal temperature Compressed air increases the oxidation of molten aluminum in the holding furnace. In addition, after the pressure is released, the high-temperature air in the furnace is directly discharged into the atmosphere, which causes energy waste due to heat loss.
