Abstract

The invention belongs to the manufacturing method of aluminum alloy, and particularly relates to an aluminum alloy continuous extrusion temperature control method for an air conditioner. The invention mainly solves the problems of prior art such as large production energy consumption and low discharging speed, and provides the aluminum alloy continuous extrusion temperature control method capable of saving energy resources and having high extrusion discharging speed. The aluminum alloy continuous extrusion temperature control method comprises the following steps of: feeding normal-temperature aluminum alloy blank into a mold, and extruding the aluminum alloy blank by an extrusion wheel to generate heat so as to improve the temperature of the aluminum alloy blank to the extrusion temperature, so that the aluminum alloy blank can generate thermal deformation during extrusion.

Description

technical field [0001] The invention belongs to the manufacturing method of aluminum alloy. In particular, it relates to an aluminum alloy continuous extrusion temperature control method for air conditioners. Background technique [0002] In the continuous extrusion process of aluminum alloy, the aluminum alloy billet is formed into a finished product through the feed wheel, extrusion wheel and extrusion die. In this process, the temperature of the extrusion wheel is relatively high, and it is difficult to control. As the strength of the aluminum alloy billet increases, the extrusion force required for extrusion will be greater, and the temperature of the extrusion wheel will be higher. . However, the structure of aluminum alloy is extremely sensitive to temperature. When the temperature is too high, it is easy to form coarse grains and even cause overburning. If the extrusion temperature is adjusted by controlling the extrusion speed, the quality of the finished aluminum...
