宝钢湛江高效板坯连铸机设计实践

2013年宝钢决定将宝钢罗泾已停产的两台单流2 300mm板坯连铸机扇形段主体设备搬迁到宝钢湛江钢铁基地,合并改造为一台双流连铸机,中冶赛迪承担总体设计和主要设备供货。中冶赛迪在设计阶段通过采用结晶器在线热调宽技术、上装引锭杆技术、铸流双跟踪和恒拉速等技术,实现了连铸生产高效率;通过独立设置机械维修车间、公辅设施紧凑化布置、冷却水阀站和液压阀站紧凑化布置、冷却水泵站露天布置等方式,实现了连铸生产低成本。

Design practice of high- performance slab caster in Baosteel Zhanjiang

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.
