Aluminum alloy high-speed casting and rolling technology

Abstract

The invention provides an aluminum alloy high-speed casting and rolling technology. A casting nozzle and a casting and rolling roller are applied to the aluminum alloy high-speed casting and rolling technology, wherein the length of a casing and rolling area is 50-65 mm; the temperature of molten aluminum in a front box is 680-710 DEG C; the casting and rolling speed is 1.0-1.2 m / min; the temperature of cooling water of the casting and rolling roller is 35-55 DEG C; and the pressure of the cooling water is 0.3-0.45 MPa. The aluminum alloy high-speed casting and rolling technology further comprises arc blocks; the arc blocks are positioned at the upper and lower ends of an outlet of the casting nozzle, and are connected with the casting and rolling nozzle. A density meter and a temperature sensor are applied to the aluminum alloy high-speed casting and rolling technology; the density meter and the temperature sensor are connected with a controller; the casting nozzle is connected with the controller; and the controller controls the temperature of the casting nozzle so as to control the rise and the drop of the temperature of the molten aluminum. According to the technology, the casting and rolling roller is lubricated and the temperature of the molten aluminum in the casting nozzle is controlled, so that the casting and rolling efficiency is improved, and the casting and rolling speed of an aluminum alloy is accelerated.

Description

technical field [0001] The invention belongs to a metal forming method, in particular to an aluminum alloy high-speed casting and rolling method. Background technique [0002] Aluminum alloy is a relatively young metal material, which only began to be used industrially in the early 20th century. During World War II, aluminum was mainly used in the manufacture of military aircraft. After the war, due to the sharp decrease in the demand for aluminum in the military industry, the aluminum industry began to develop civilian aluminum alloys, expanding its application scope from the aviation industry to the construction industry, container packaging industry, transportation industry, electric power and electronics industry, Various sectors of the national economy such as machinery manufacturing and petrochemicals are applied to people's daily lives. At present, aluminum is used in a large amount and in a wide range, second only to steel, and has become the second largest metal m...

Problems solved by technology

[0003] The twin-roll casting and rolling technology has been used in the aluminum alloy industry for nearly 50 years, although the twin-roll casting and rolling technology can produce high-quality aluminum alloy cast strips and has many advantages, such as direct production of thin strips from metal melts, rapid solidification, equipment The cost is low, but at the same time, twin-roll cast-rolled aluminum alloys also have many disadvantages, such as low casting-rolling speed, easy sticking of rolls, and fewer varieties of cast-rolled aluminum alloys.
