Abstract

The invention discloses a processing technology of an aluminum alloy outer plate for a cold chain transport carriage, and relates to the technical field of aluminum alloy material processing. The invention uses Al as the main material, and Mg, Ti, Pb, Sn, Ni, Fe, Bi, As , Y, and Nd are used as auxiliary materials. Through the control of raw material formula and processing technology, the aluminum alloy outer plate suitable for the compartment of cold chain transport vehicles is obtained. The mechanical properties of the aluminum alloy outer plate are excellent, and the thermal insulation performance is good; The use of the degassing agent makes the hydrogen content in the refined aluminum alloy melt not exceed 0.08ml / 100g Al.

Description

Technical field: [0001] The invention relates to the technical field of aluminum alloy material processing, in particular to a processing technology for an aluminum alloy outer plate used in a cold chain transport carriage. Background technique: [0002] The cold chain transport vehicle is a vehicle used to transport frozen or refrigerated goods. It is equipped with a refrigeration unit and is laid with materials with low thermal conductivity on the inner wall. The interior of the traditional cold chain transport vehicle adopts a combination structure of steel frame and wood, which has poor thermal insulation performance, heavy structure, easy to rust, and poor durability. At present, aluminum alloy profiles are mostly used as the material for the compartment of cold chain transport vehicles, but polyurethane insulation materials with low thermal conductivity need to be laid on the inner wall. The thermal conductivity of pure aluminum is 217.7W / (m.K). The thermal conductivi...
