Aluminum product processing technology, forging

Forging is an ancient process that was born almost simultaneously with the large-scale production of pure metals. The thousands of years of human discovery and use of metals have been accompanied by the development of forging technology. Forging is one of the basic processes in the mechanical manufacturing industry(Aluminum foil manufacturer china). Forged parts play an important role in machinery and equipment. However, in aluminum, the proportion of forgings is not large, for example, in the 27 years from 1956 to 1983, China Northeast Light Alloy Co., Ltd. produces a total of 233,832 tons of aluminum, including 170,614 tons of die forgings and 3,728 tons of free forgings, accounting for 0.75% and 0.16% of the total respectively. The industrialized countries account for a slightly larger proportion, but they are not. More than 2%.

The industrial production of aluminum alloy forgings in the world began in the early part of the last century. Since the commercial extraction of primary aluminum began in 1888, the modern industrial production of aluminum alloy forgings in China began in 1961 with the completion of the second-phase forging workshop of Northeast Light Alloy Co., Ltd. , design production capacity: die forgings 370 tons / year, free forgings 80 tons / year. The main equipment was imported from the Soviet Union: 1 set of 100MN die forging machine, 1 set of 50MN die forging machine, 1 set of 30MN die forging machine, 1 set of 3MN forging press and 2 sets of model milling machine.

On July 1, 1970, the Southwest Aluminum Processing Plant (now known as Southwest Aluminum (Group) Co., Ltd.) built a 8-column vertical 300MN die forging machine designed and manufactured by China's No. 1 Heavy Machinery Company, and 60MN vertical free forging. 1 set, the forging production capacity of 24,500 tons / year.

In the past 40 years, it has been a period of great development for China's aluminum alloy forging industry. In 2017, there were about 35 enterprises that can produce aluminum alloy forgings in China, with a total production capacity of about 100,000 tons/year. China has been ranked among the world's first aluminum forgings. It is the world's largest production capacity. It has the world's largest 800MN forging press. There are about 140 forging presses in the country, which can produce all kinds of forgings needed for national economic construction. Northeast Light Alloy Co., Ltd. and Southwest Aluminium (Group) Co., Ltd. produced a forging ring with a diameter of ≤10m (pictured) to ensure the launch of the spacecraft as scheduled. Southwest Aluminum (Group) Co., Ltd. produces aluminum alloy die forgings with thousands of Boeing aircraft.
