The device for preparing the nickel-enriched aluminum silicon alloys by using the electromagnetic method comprises a feeding device, a heating furnace, an induction heating and stirring device, an air extracting system and a cooling water system. the device is convenient to add raw materials; the raw materials can be blocks or particles; the steps from charging to ingot casting are continuously finished to prevent secondary pollution of products; the process flow of the device casting the nickel-enriched aluminum silicon alloys is short; the operation process is convenient; the production cost is low; and according to experimental analysis, compared with a traditional method, the nickel element distribution of the cast nickel-enriched aluminum silicon alloys is more uniform, and the nickel phase size is finer. Meanwhile, aluminum silicon alloy grains are refined, so that the high-temperature metal strength and toughness of the alloys are further improved.

Description

technical field [0001] The invention relates to a device and method for preparing a nickel-rich aluminum-silicon alloy by using an electromagnetic method, and belongs to the technical field of electromagnetic metallurgy and continuous casting. Background technique [0002] Aluminum-silicon alloy has become one of the most important alloys in the world industry due to its superior mechanical and casting properties. Adding a small amount of nickel and copper into the aluminum-silicon composite machine can change its performance and improve the high-temperature strength and heat resistance of the alloy. Therefore, nickel-rich aluminum-silicon alloys have become the manufacturing materials for cylinder pistons of internal combustion engines for domestic and foreign vehicles. Effective stirring in the preparation process of nickel-rich aluminum-silicon alloy can, on the one hand, make the distribution of nickel in the alloy more uniform and improve the performance of the alloy; o...
