Bazhou Sangan's continuous galvanizing aluminum magnesium unit "no oxidation furnace renovation project" has been completed and put into production

Bazhou Sangan Continuous Galvanized Aluminum Magnesium Unit
Completion and commissioning of the "oxidation-free furnace renovation project"

On March 18, 2024, the No. 3 continuous hot-dip galvanizing aluminum magnesium unit "oxidation-free furnace renovation project" of Bazhou Sangan Technology Co., Ltd. ("Sangan Technology"), undertaken by Huangshi Shanli Technology Co., Ltd. ("Shanli Technology"), was completed and put into operation.

The No. 3 continuous hot-dip galvanizing aluminum magnesium unit mainly produces 1.0mm-4.0mm thick zinc-aluminum-magnesium products. Established in 2020, it had problems such as deformation of the oxidation-free furnace shell steel structure, damage to burner bricks, unstable burner combustion conditions, and relatively small production capacity. This made it difficult to meet the production needs of Sangan Technology's products and posed significant safety hazards. Therefore, Sangan Technology commissioned Shanli Technology to design and renovate the oxidation-free furnace section of this unit to improve product quality and capacity.

 

 

 

 

 

 

 

 

 

Based on the needs of Sangan Technology, Shanli Technology integrated the original process and configuration of the No. 3 unit and designed and manufactured a new oxidation-free furnace body structure. It adopted lightweight furnace lining, low-nitrogen high-efficiency combustion, multi-level waste heat utilization, and rapid and uniform heating of the strip into the furnace. During the renovation, the two companies cooperated closely, overcoming numerous difficulties and successfully completing the task within the contract period. The trial production of aluminum-zinc-magnesium products was successful on the first attempt, with excellent product performance. The corrosion resistance of thick plates is significantly improved compared to the original galvanized products, production capacity is increased, and energy saving is significant. This renovation has been highly recognized by Sangan Technology.

Sangan Technology and Shanli Technology are long-term partners. In 2018, Shanli Technology undertook the construction of two continuous hot-dip galvanizing production lines (No. 1 and No. 2). In 2023, it once again undertook the design, development, and construction of two high-end continuous hot-dip galvanizing aluminum magnesium units, which are currently under construction. From 2021 to 2024, Shanli Technology has also undertaken several technical renovation projects for other units of Sangan Technology. Over the years, the technical cooperation between the two parties in the field of strip coating has continuously strengthened, achieving new breakthroughs and building trust. This has contributed to Sangan Technology's continuous improvement of its products and innovation in China's coating technology and coating product development.
