Abstract

The invention relates to a production technology for an aluminium alloy casting rod special for automobile Peugeot hubs. The casting rod comprises the following compositions in percent by weight: 95.95-97.30% of Al, 0.8-1.3% of Si, 0.20-0.4% of Fe, 0.1% or less of Cu, 0.5-0.9% of Mn, 0.8-1.0% of Mg, 0.15% or less of Cr, 0.1% or less of Zn and 0.05-0.10% of Ti. The production technology comprises: weighing the compositions, placing in a melting furnace for melting with the melting temperature of 745 DEG C + / -5 DEG C, removing slag by employing a metallurgy slag-removing apparatus, so as to prepare an aluminium alloy melt; introducing the aluminium alloy melt into a standing furnace, adding a fluxing agent powder No. 2 for refining for 30 min, then standing the refined alloy aluminium melt in the standing furnace with the standing furnace temperature of 735 DEG C-745 DEG C for 30 min; performing molding casting on the aluminium alloy melt by employing a hot-top casting machine, so as to obtain an aluminium alloy casting rod; processing the casted aluminium alloy casting rod, and placing in a homogenization furnace to process for 12 h; transferring the aluminium alloy casting rod subjected to homogenization processing into a cooling chamber, and employing a blower fan to perform forced cooling, so as to prepare the aluminium alloy casting rod special for automobile Peugeot hubs.

Description

technical field [0001] The invention relates to a production process of aluminum alloy casting rods specially used for Peugeot automobile wheels, in particular to the production technology of aluminum alloy casting rods specially used for manufacturing Peugeot automobile wheel hubs, and belongs to the technical field of aluminum alloy casting rod production. Background technique [0002] The wheel hub is an important part of the car, and its quality directly affects the performance and aesthetics of the car. The production process of automobile wheels requires very strict requirements on the performance of the wheel materials. The produced wheels must not only have good rotational bending performance, but also have excellent impact toughness and good wear resistance. In recent years, most of the wheels of high-end cars at home and abroad are made of aluminum alloy materials. [0003] Automobile hubs are generally made of aluminum alloy materials by die casting. The aluminu...
