Problems solved by technology

However, since the heat shield needs to match the shape of the auto parts, the overall size of the heat shield is generally large and there are many free-form surfaces, which have the characteristics of obvious ups and downs, and are prone to wrinkling and stretching cracks during molding. With the development of lightweight automobiles and the increase in the demand for energy saving and emission reduction, the thickness of the heat shield is also constantly thinning, which has higher requirements for the processing performance of the material itself, especially the plastic deformation ability.

Abstract

The invention belongs to the field of aluminum material processing and relates to a manufacturing method of an aluminum material for an automobile heat insulation sheet. The method comprises the following steps that: raw materials are added into a smelting furnace; after the raw materials in the smelting furnace are completely liquefied, component blending is conducted, and an obtained material isintroduced into a holding furnace after being heated; molten aluminum in the holding furnace is subjected to cast rolling, so that a cast and rolled coil can be produced; and cold rolling and annealing are performed after the cast rolling is performed. According to the manufacturing process of the aluminum material for the automobile high-extensibility heat insulation sheet, waste self-produced aluminum, waste commercial aluminum and aluminum ingots for re-melting are used as raw materials; and through control over a processing rate and annealing, the elongation and plastic deformation ability of the aluminum material are improved.

Description

technical field [0001] The invention belongs to the field of aluminum material processing, and in particular relates to a method for manufacturing an aluminum material for an automobile heat insulation sheet. Background technique [0002] Automobile heat shield is a component around the engine and exhaust system of the automobile. It can effectively isolate heat transfer, reduce problems around the engine, chassis and cab, protect the normal operation of the engine and chassis electronic components, and improve driving comfort. However, since the heat shield needs to match the shape of the auto parts, the overall size of the heat shield is generally large and there are many free-form surfaces, which have the characteristics of obvious ups and downs, and are prone to wrinkles and cracks during molding. With the development of lightweight automobiles and the increase in the demand for energy saving and emission reduction, the thickness of heat shields is also constantly thinni...
