Abstract:The main segment equipment of the shutdown 2- set single- strand 2 300 mm slab casters at Baosteel Luojing Plant was relocated to Baosteel Zhanjiang Base in 2013, which was merged into an upgraded two- strand slab caster. CISDI was contracted the general design and package supply of the main equipment. CISDI applied the multiple advanced technologies in engineering phase for improving the productivity, including the mould inline width adjustment, top- inserting dummy bar, strand dual- tracking and constant casting speed. And the arrangements in engineering was also optimized by the independent mechanical maintenance shop, compact layout of utilities and cooling water valve station and hydraulic valve station, and open yard for cooling water pump station, which can save the continuous casting production costs.
