The Tongxiang intelligent base's second roving phase, a 150,000-tonne-per-year alkali-free tank-furnace line, was ignited on 9 June 2020. It is stored separately from phase I commissioned in 2018, despite equal stated capacity and the same base. The disclosed milestone is ignition; the passage does not provide the line's full-year realised output or require that its design capacity be treated as production for all twelve months.
