Original title: New progress has been made in the national major short-board equipment project undertaken by our district
The 2400mm air-cushion continuous heat treatment production line was officially launched in Nannan Aluminum Processing
On July 1, a 323-meter-long air-cushion heat treatment production line running through the west and east was eye-catching at the site of the cold rolling manufacturing center of Guangxi Nannan Aluminum Processing Co., Ltd., a subsidiary of Guangxi Investment Group. It is produced smoothly in a set of domestically developed air cushion furnaces.
On the same day, the 2400mm air-cushion continuous heat treatment production line of the national major short-board equipment project was officially launched in Nannan Aluminum Processing, marking the phased progress of the national major short-board equipment project undertaken by our district. It is understood that this air-cushion continuous heat treatment production line is the first continuous heat treatment production line of high-quality aluminum alloy plates and strips independently developed, designed and manufactured in China, breaking through the “stuck neck” problem in my country’s core equipment air-cushion heat treatment equipment manufacturing. , to achieve independent innovation. “After this production line is officially put into operation, it will increase our company’s high-end aluminum production capacity with an annual output of 50,000 tons, with an annual output value of about 1.5 billion yuan, which will provide strong support for the processing of Nannan Aluminum and increase efficiency. Contribute to the high-quality development of the industry.” Yu Fengzhi, chief engineer of Nannan Aluminum Processing, told reporters.
Since the start of the project in 2019, the technical team has also successively conquered “aerodynamic characteristics and dynamic balance floating mechanism of wide-width metal strip air cushion floating”, “strong convective heat transfer characteristics and air flow distribution mechanism”, “high-strength resistance The problems such as rapid movement and continuous quenching of aluminum alloy high-temperature strips, “chromium-free surface passivation of aluminum alloy automobile sheets”, and “intelligent process control system for continuous heat treatment and surface treatment of large strips” have been successfully realized. Eight functional tests such as stretch-bending straightening, surface treatment, cleaning, edge trimming, pre-aging, and oiling.
“This air-cushion continuous heat treatment production line is completed and put into operation, which will break the foreign monopoly on the key equipment of aluminum alloy sheet heat treatment production line, and fill the gap of my country’s high surface quality, high performance aluminum alloy sheet and strip heat treatment equipment, which is of great significance.” Northeast China Li Yong, a doctoral tutor of the State Key Laboratory of Rolling Technology and Continuous Rolling Automation at the university and general manager of Guangxi Advanced Aluminum Processing Innovation Center, introduced.
At present, Nannan Aluminum Processing is vigorously promoting the high-end, intelligent and green development of the traditional aluminum industry. “We will start the ignition of the 2400mm air-cushion continuous heat treatment production line as a new starting point to help the entire aluminum industry chain in the autonomous region strengthen the chain, supplement the chain and extend the chain, and build a benchmark enterprise for Guangxi’s industrial revitalization and industrial rise.” Yu Fengzhi said.
