The invention discloses vacuum degassing equipment comprising a degassing cavity, a feed inlet, a vacuum air extractor and a discharge outlet. The degassing cavity comprises a ceramic filtration plate, air bricks, a thermal insulating wall and a flow hole plug. The feed inlet is formed in the side wall on the upper portion of the degassing cavity. The discharge outlet is formed in the side wall onthe lower portion of the degassing cavity. The discharge outlet and the feed inlet are not in the same side. An air extraction opening of the vacuum air extractor is inserted into the degassing cavity from above the degassing cavity. The air bricks are arranged at the bottom of the degassing cavity. A step projection is further arranged in the degassing cavity. A through hole is formed in the middle. The flow hole plug is arranged in the through hole of the step projection. Degassing and deslagging efficiency of the vacuum degassing equipment is high, a foundation is laid for solving the problem of secondary pollution, comprehensive deslagging efficiency is also better than that of a traditional method, and quality of a cast ingot is good. Various devices are modularized, the number of the devices is reduced, a launder is shortened, and assembly and use are convenient. Meanwhile inert gas can be recycled, and investment and cost are reduced.
Description
technical field [0001] The invention relates to the technical field of metallurgy and metal material processing, in particular to a vacuum degassing device. Background technique [0002] Many auto parts, such as automobile engine casings and automobile engine rotors, are produced and processed by aluminum hydraulic casting production methods. As the most commonly used casting die-casting material, aluminum liquid mainly contains three gases: hydrogen, oxygen and nitrogen, and the hydrogen content accounts for about 85%. Hydrogen dissolves and precipitates in aluminum and its alloys, which will cause pinholes, Pores, etc., eventually lead to a great reduction in the mechanical properties and internal quality of the casting. Therefore, filtering and degassing the molten aluminum is particularly important in the field of die-casting of aluminum parts. Rotor degassing is commonly used now, which consumes a lot of rotors and requires the use of multiple devices, which increases...
