Method for rolling large-sized aluminum alloy ring piece and performing solid solution treatment by using electric furnace

Abstract

The invention relates to a process method for rolling and molding a large-sized aluminum alloy ring piece and performing solid solution treatment by using an electric furnace, and belongs to the field of manufacturing of non-ferrous alloys. The method comprises the following steps of: determining the aluminum ingot rolling specification and the rolling process upsetting deformation ratio of an aluminum alloy ring piece blank and heating temperatures and temperature preservation time process parameters during solid solution aging treatment of the electric furnace through the rolling and molding ingot specification and the rolling process parameter of an aluminum alloy, wherein in the determined process, the upsetting deformation ratio of the rolled and molded aluminum ingot with the specification of phi 410*1,000mm is 85 to 88 percent; performing a solid solution process at the temperature of between 475+/-5 DEG C for 500 minutes in a resistance furnace; performing water quenching at the temperature of 65 DEG C, wherein the straightening cold deformation amount is 3 to 4 percent; and performing aging treatment by using the electric furnace at the temperature of 130+/-5 DEG C for 7 hours, and raising the temperature to 170+/-5 DEG C for 8 hours. By the novel process method for rolling and molding a large-sized aluminum alloy and producing a blank through solid solution thermal treatment of the electric furnace, feeding amount is reduced by 38 percent, and the efficiency is improved by 30 percent; and the method has the characteristics of short production period, high quality stability and the like, is safe, energy-saving and environment-friendly, has obvious economic benefits and is positioned in a leading level in China.

Description

Technical field: [0001] The invention relates to a process method of rolling forming and electric furnace solid solution treatment of a large aluminum alloy ring, which belongs to the field of nonferrous alloy manufacturing. Background technique: [0002] The blank forming process of large aluminum alloy rings has always been free forging with hydraulic press horse frame reaming, which requires more aluminum ingots, large processing allowances, and low production efficiency. In addition, the billet is heated and solid-solution treated in a salt-bath furnace after forging, which has problems such as small furnace loading, high energy consumption, heavy pollution, and untimely supply. Invention content: [0003] The purpose of the present invention is to provide a large-scale aluminum alloy ring rolling and electric furnace solution treatment method, which solves the problems of long forming time, high energy consumption, low solution treatment efficiency and large pollution...
