The rolling process of groove shaped rails for trams is complex, and the entry threshold for overseas markets remains high. Angang Steel withstood the dual pressure of tight construction schedule and high standards, formed a special team to complete technical research and development, and shipped the first batch of groove rail products overseas, filling the gap in the export of domestic special steel rails and adding chips to China's participation in global infrastructure competition for rail transit steel.

Overcoming production difficulties

Groove rails are known as the king of rails, with complex cross-sectional structures, high assembly and rolling process difficulties, strict standards for dimensional flatness and internal quality, and high technical audit thresholds for overseas customers.

This order has a tight delivery cycle and strict quality requirements. Angang Steel's large-scale headquarters has established a special research and development team to optimize and upgrade the production process around hole design quality control, and to add internal control indicators on top of the general testing standards. Technical personnel are on duty 24 hours a day, repeatedly adjusting the rolling mill pass and rolling parameters, and implementing quality control in various positions of heating, rolling, and non-destructive testing. After half a month of hard work, the product yield and production efficiency have been significantly improved, ensuring smooth delivery of orders. Keywords: Angang Steel, groove rail outlet

Targeting overseas markets

This export has achieved a breakthrough of zero export of domestically produced tram trough rails, becoming a new business card for China's special steel for rail transit to go global. Relying on mature heavy rail production line technology, Angang Steel will continue to enrich its high-end rail product matrix and deeply layout in the overseas urban rail transit field. Seize the opportunity of infrastructure construction along the the Belt and Road, seize overseas orders with excellent product strength, continue to expand the influence of domestic rails in the global market, and promote more special rail transit steel to go global.Editor/Min Jing
