Guanzhou Group Dingxin's No. 2 continuous hot-dip galvanizing unit "zinc-aluminum-magnesium transformation project" has officially started production

Guanzhou Group Dingxin Continuous Hot-Dip Galvanizing Line 2
The "Zinc-Aluminum-Magnesium Modification Project" Officially Starts Production

On July 6, 2023, the zinc-aluminum-magnesium modification project of the continuous hot-dip galvanizing line 2 of Shandong Guanzhou Group Dingxin Plate Technology Co., Ltd. (hereinafter referred to as "Guanzhou Dingxin"), undertaken by Huangshi Shanli Technology Co., Ltd. (hereinafter referred to as "Shanli Technology"), officially started production.

Guanzhou Dingxin's continuous hot-dip galvanizing line 2 is a turnkey project of Shanli Technology, completed in 2013 with an annual output of 300,000 tons, and has been in operation for 10 years. To improve equipment level and product structure, Guanzhou Group commissioned Shanli Technology to carry out technical transformation of the unit, which will enable the production of various high-end zinc-aluminum-magnesium products such as low-aluminum-low-magnesium, low-aluminum-high-magnesium, medium-aluminum-low-magnesium, and medium-aluminum-high-magnesium, while increasing product specifications to 2.5mm thick x 1350mm wide.

Shanli Technology started researching zinc-aluminum-magnesium coating technology in 2015 and has gained first-hand production experience in the implementation of zinc-aluminum-magnesium coating unit transformation projects for Shandong Korui and Guanzhou Group headquarters. Shandong Korui is one of the earliest private enterprises to try zinc-aluminum-magnesium production; following the commissioning of the high-aluminum zinc-aluminum-magnesium unit built for Panzhihua Iron and Steel Group Chengdu Plate in 2020, two production lines professionally designed for Shandong Qian Steel Company's zinc-aluminum-magnesium plating were also successfully put into operation in 2022.

 

 

 

 

 

 

 

 

 

 

In this zinc-aluminum-magnesium modification project, according to the characteristics and site conditions of Guanzhou Dingxin's No. 2 galvanizing line, Shanli Technology upgraded and modified the narrow lap welding machine, zinc pot, air knife, and control system of the No. 2 hot-dip galvanizing line, and developed protective gas preheating devices, high-efficiency mobile air cooling, and slag discharge furnace nozzles, realizing a comprehensive upgrade of the unit from product specifications to product types! To ensure the owner's early commissioning, Shanli Technology and Guanzhou Dingxin constantly communicated, coordinated, and cooperated with each other. Before the unit was shut down, all prefabricated equipment was prepared; after the unit was shut down, both parties cooperated to install steel platforms, cooling tower equipment, and other individual equipment, and carried out furnace drying and zinc-making work simultaneously; finally, the project was completed and put into operation in only 10 days!

Guanzhou Group is a modern enterprise integrating the research, production, and operation of cold-rolled sheets, galvanized sheets, and color-coated sheets. It has formed a production scale of 2 million tons of cold-rolled sheets, 1.6 million tons of galvanized (aluminum) sheets, 1.3 million tons of color-coated sheets, 400,000 tons of annealed sheets, and 3,000 tons of high-performance neodymium iron boron rare earth permanent magnet materials annually. It has supporting thermal power plants and natural gas energy projects, creating a complete green ecological industrial chain; it is a national manufacturing single-item champion enterprise, an environmental protection performance A-level enterprise, the industry's first 3-star certified enterprise for green building materials products, and the drafting unit of 17 national, industry, and group standards such as "Color-coated steel sheets for building decoration". Guanzhou's high-quality plate materials have been successfully applied to the construction of Wuhan Huoshenshan and Leishenshan epidemic prevention hospitals, Qingdao Jiaodong and Haikou Meilan international airports, Jinan and Shanghai high-speed railway stations, Shenzhen and Xi'an international convention and exhibition centers, and a large number of key projects such as the National Ice Sports Training Center, the National Speed Skating Oval, the Russian Winter Olympics venue, and the Saipan Leisure Resort Center in the United States.

Since 2003, when Shanli Technology built the first continuous hot-dip galvanizing line (Line 1) for Guanzhou Group, the two companies have cooperated deeply and worked together for more than 20 years, building a total of 6 new complete lines and carrying out multiple upgrades and transformations for Guanzhou Group; in 2023 alone, Shanli Technology and Guanzhou Group have cooperated to put into operation two transformation projects! Currently, Guanzhou Group is the largest private enterprise producing galvanized sheets and color-coated sheets in China, and Shanli Company is a national-level specialized and new "small giant" enterprise in the coating and plating equipment field; the two units will inevitably have more cooperation in the future, contributing greater strength to China's plate and strip heat treatment industry chain!
