Production process of aluminium alloy casting rod specially used for Ford automobile rotary-swaged hub decorative rings

Abstract

A production process of an aluminium alloy casting rod specially used for Ford automobile rotary-swaged hub decorative rings. The aluminium alloy casting rod comprises the following components by weight: 95.95-97.30% of Al, 0.95-1.05% of Mg, 0.72-0.8% of Si, 0.21-0.24% of Cu, 0.20-0.24% of Fe, 0.16-0.20% of Cr, 0.06-0.10% of Mn, 0-0.05% of Zn, and 0-0.05% of Ti. The process comprises the following steps: melting the components of Al, Mg, Si, Cu, Fe, Cr, Mn, Zn, and Ti in a melting furnace according to the weight ratios, uniformly stirring the melt, removing slag to obtain aluminium alloy melt; introducing the aluminium alloy melt into a standing furnace, refining with argon, nitrogen and No.2 flux powder; allowing the refined aluminium alloy melt to stand in a standing furnace at a temperature of 735 DEG C-745 DEG C for 30 min; performing casting molding by a hot-top casting machine, performing oil-gas mixing treatment on a casting machine by using oil-gas mixing lubrication graphite ring technology to obtain the aluminium alloy casting rod; cutting the aluminium alloy casting rod, and performing uniformization treatment and cooling treatment to obtain the aluminium alloy casting rod specially used for Ford automobile hubs.

Description

technical field [0001] The invention relates to the production process of aluminum alloy casting rods specially used for forging and rotating wheel hub decoration rings of Ford automobiles, in particular to the production technology of aluminum alloy casting rods specially used for forging and rotating Ford automobile wheel hub decoration rings, which belongs to the production of aluminum alloy casting rods technology field. Background technique [0002] With the continuous improvement of the quality and strength requirements of aluminum alloy wheels in the automobile industry, the technology of producing automobile wheels by aluminum alloy forging and spinning has begun to receive attention. The aluminum alloy wheels produced by die casting and the automobiles produced by forging and spinning aluminum alloy cast rods Wheels vary widely in performance. Due to the relatively high strength of forged wheels and good mechanical properties of wheels, many high-end automobile man...

[0003] The wheel decoration ring is a decorative accessory used to decorate the car wheel. Most of the existing car wheel decoration rings are made of aluminum alloy or plastic materials. The wheel decoration rings made of ordinary aluminum alloy or plastic are cheap. However, the gloss is poor, especially when used to decorate aluminum alloy swivel wheels, resulting in extremely poor overall coordination of the wheels and affecting the overall aesthetics of the car
