On January 22nd, Valin Iron and Steel said its subsidiary Lianyuan Steel will spend 449.88 million yuan on an on-site overhaul of the 6-meter coke ovens at its coking plant. The 19-month project will fix aging issues, restore production, meet environmental standards, cut costs and achieve energy conservation goals. It will not disrupt operations or hurt finances.
Lianyuan’s coking plant has two 6-meter coke ovens launched in 2003 and 2005. After 20 years, both are at the end of their service life. Despite recent upgrades and maintenance, the aging ovens have problems: wall erosion, leaks, low efficiency and output (only 93% of design). Pollutants and energy use have also risen, failing to meet requirements.
To solve these problems, overhaul old coke ovens is critical for Lianyuan’s development. Experts note this is a common way for steel firms to ensure stable, green production. For Lianyuan, it is more than maintenance—it is a key step to comply with national policies.
The overhaul will bring four key benefits: cut pollutants to meet environmental rules; lower costs by ending costly daily maintenance and reducing external coke purchases; fill the coke shortage with more stable self-produced coke; and support energy conservation by improving efficiency.
As a key Valin subsidiary, Lianyuan focuses on green upgrades. This overhaul will boost its stability, environmental performance and cost control, strengthening Valin’s competitiveness. The project will proceed as planned, with timely updates.
