Embodiment 1

[0024] A high-efficiency and energy-saving aluminum template extrusion process method, comprising the following steps:

[0025] A. Ingredients: The mass percentage ratio of each element of the aluminum alloy profile is as follows:

[0026] element Si Mg Fe Cu mn Cr Ti Zn Ce Impurities Al content 0.65 0.50 0.1 0.015 0.015 0.015 0.015 0.015 0.02 0.10 margin

[0027] B. Melting and casting: Add the prepared aluminum alloy raw materials into the fusing furnace and mix them evenly and then flicker into liquid aluminum alloy. aluminum alloy ingot;

[0028] C. Extrusion: Preheat the cast aluminum alloy ingot and send it to the aluminum alloy extruder for extrusion molding to obtain aluminum alloy profiles. The aluminum alloy ingot is heated to the predetermined temperature and released 3 minutes in advance and exposed to the Extruded on the machine after 3 minutes in the air, the temperature difference between the core and side of t...

Embodiment 2

[0034] The difference between embodiment 2 and embodiment 1 is that the mass percentage ratio of each element of the aluminum alloy profile in step A is as follows:

[0035] element Si Mg Fe Cu mn Cr Ti Zn Ce Impurities Al content 0.75 0.54 0.15 0.015 0.015 0.015 0.015 0.015 0.02 0.10 margin

Abstract

The invention belongs to the technical field of aluminum alloy production, and relates to a high-efficiency energy-saving aluminum template extrusion process method. Aluminum alloy raw materials comprise 0.65-0.75% of Si, 0.5-0.54% of Mg, 0.1-0.15% of Fe, not more than 0.015% of Cu, not more than 0.015% of Mn, not more than 0.015% of Cr, not more than 0.015% of Ti, not more than 0.015% of Zn, notmore than 0.02% of Ce, not more than 0.05% of single impurity, and the balance Al, wherein the content of the total single impurities is not more than 0.15%, and Mg / Si is less than 1.73; and by matching the reasonable process and the formula and strictly controlling various parameters in the process, the extrusion speed of an aluminum template is greatly increased, the production efficiency is improved, the production period is shortened, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy production, and relates to an extrusion process method of high-efficiency and energy-saving aluminum templates. Background technique [0002] Aluminum is one of the most abundant elements in the earth's crust, with a content of 8.8%, ranking first among the four major metal elements and accounting for 1 / 3 of the entire mass of metal elements. Due to the improvement of aluminum technology, the aluminum industry is developing at an astonishing speed. By 2004, the world's aluminum output reached 29.8 million tons, of which my country's output was 6.8 million tons, ranking third in the world, and there were more than a thousand varieties of aluminum alloys. Due to the development of aluminum materials, the processing technology of aluminum has also been advanced by leaps and bounds. Due to its light weight, high specific strength, good low temperature performance, good plasticity, easy proces...
