Embodiment 1

[0017] Embodiment 1: A continuous casting and extrusion process of aluminum alloy profiles, the production process of the high weather resistance aluminum alloy profiles includes the following steps:

[0018] The first step, smelting preparation, first add aluminum into the furnace according to the proportion, and heat it to a molten state, then add an appropriate amount of modified fly ash and spread it evenly, then add an appropriate amount of grain refiner for refining, and finally Add alloying elements, and wait until the molten aluminum and the added alloying elements are fully melted and mixed evenly.

[0019] The second step is casting and heat preservation. The molten aluminum alloy is continuously cast and formed through the casting mold, and the high-temperature solid or semi-solid aluminum alloy ingot after casting is forced to cool down to 500 ° C, and then kept for 1 hour;

[0020] The third step is extrusion molding. Install the heat-insulated aluminum alloy ingo...

Embodiment 2

[0023] Example 2: The first step, smelting preparation, first add aluminum into the melting furnace according to the proportion, and heat it to a molten state, then add an appropriate amount of modified fly ash and spread it evenly, and then add an appropriate amount of grain refiner Refining, and finally adding alloying elements, after the molten aluminum and the added alloying elements are fully melted and mixed evenly,

[0024] The second step is casting and heat preservation. The molten aluminum alloy is continuously cast and formed through the casting mold, and the high-temperature solid or semi-solid aluminum alloy ingot after casting is forced to cool down to 600 ° C, and then kept for 0 hours;

[0025] The third step is extrusion molding. Install the heat-insulated aluminum alloy ingot on the extruder and force it to cool down to 400°C, and then pass through the extruder die to extrude a specific shape of aluminum profile. The extrusion speed is 50 meters. / minute;

Abstract

The invention discloses a continuous casting and extrusion process of an aluminum alloy section, which comprises steps such as smelting and preparing, casting and temperature keeping, extrusion and molding, cooling and quenching, straightening and tempering, and the like. The aluminum alloy section production process omits multiple heating and cooling procedures in the traditional process and omits an aluminum alloy section cutting procedure, thus greatly simplifying the aluminum alloy section production procedure, improving the production efficiency, reducing the loss of the aluminum alloy section in the cutting process, greatly improving the production efficiency, lowering the production cost of the aluminum alloy section, greatly reducing energy consumption and resource loss, and reducing pollution to the natural environment.
