Technological breakthroughs

With a sense of responsibility, innovative thinking, and a proactive approach to research and technical improvement from practical production, Mr. Văn Hồng Sơn, General Director of Van Dien Fused Phosphate Fertiliser Joint Stock Company, has successfully developed and implemented a blast furnace insulation kiln technology innovation, delivering savings in excess of VND 10.46 billion. In recognition of this achievement, he was awarded the Creative Labour Certificate 2025 by the Vietnam General Confederation of Labour, marking significant contributions to research, technical solutions, and enhanced production efficiency at the enterprise.

Personal Mark in Blast Furnace Technology Innovation

In his management and production leadership, Mr. Văn Hồng Sơn placed strong emphasis on research, seeking solutions to overcome technical limitations that directly affected blast furnace efficiency—a critical stage in fused phosphate fertiliser production.

Prior to the innovation, blast furnaces were constructed with steel plate and operated at internal temperatures of around 1,500°C, cooled externally by circulating water. This structure resulted in considerable heat loss, unstable production processes, frequent incidents, and high consumption of coal, wood, and electricity, raising the cost of semi-finished fertiliser production.

In response, Mr. Văn Hồng Sơn developed the initiative “Research and development of insulation kiln technology for stable and more efficient blast furnace production.” The solution involved using high-alumina refractory bricks to insulate the furnace shell, reducing heat loss, increasing equipment stability, and lowering energy consumption during production.
A key highlight is that the innovation was successfully implemented across all three of the company’s blast furnaces. Post-improvement, the furnaces operated more stably, with fewer technological incidents and reduced production interruptions. Savings in coal, wood, and electricity directly lowered production costs for fused phosphate semi-finished goods and improved working conditions for employees.

The Initiative Delivers Over VND 10.46 Billion in Savings

The effectiveness of Mr. Văn Hồng Sơn’s research and technical improvements is demonstrated by clear economic results. As of 31 December 2025, the insulation kiln innovation across all three blast furnaces had generated total net savings of VND 10,461,737,131.

Of this, blast furnace No. 1 contributed more than VND 996 million; blast furnace No. 2 nearly VND 5.49 billion; and blast furnace No. 3 almost VND 3.97 billion. These results highlight the practical effectiveness of the solution and its ability to translate technical improvements into tangible economic benefits for the business.

Behind the figure of over VND 10.46 billion lies a process of research, exploration, and problem-solving in real-life production. The initiative demonstrates an approach focused on operational efficiency, combining energy saving and cost reduction with production line stability. Its successful implementation across all three blast furnaces also confirms the applicability of the solution at Van Dien Fused Phosphate Fertiliser Joint Stock Company.

The Creative Labour Certificate 2025 from the Vietnam General Confederation of Labour is recognition of Mr. Văn Hồng Sơn’s achievements in research, technical improvement, and production efficiency enhancement. This is not only a tribute to an initiative with substantial economic value, but also an acknowledgement of proactive innovation, practical research, and the effective application of solutions by a business leader.

Mr. Văn Hồng Sơn’s achievement contributes to spreading the creative labour movement at Van Dien Fused Phosphate Fertiliser Joint Stock Company in particular, and the Vietnam National Chemical Group in general, encouraging staff, engineers, and workers to maximise their expertise, proactively improve technology, enhance productivity, and use resources efficiently—thus supporting the stable, sustainable development of the enterprise.
