薄板坯连铸连轧技术将传统钢铁制造流程独立分散的工序有机集成,以高效、节能、环保的优势受到全球广泛关注,在世界范围内得到迅速推广。传统炼钢工艺中,铸钢后形成的900℃钢坯需降至室温,运输至轧钢机组后再加热到1 200℃才能轧制,中间巨大能量损耗可想而知。连铸连轧,薄板坯铸完即可直接轧制,既能避免能量损失又能充分发挥流程特点,开发与之相适应的低成本高性能钢,具有工序简单、投资少、生产周期短、能耗低等优点。
The thin slab continuous casting and rolling technology integrates the traditional processes of steel manufacturing with independent dispersion. It is widely concerned in the world with the advantages of high efficiency, energy saving and environmental protection, and has been rapidly promoted in the world. In the traditional steelmaking process, the 900 ° C billet formed after the steel casting needs to be lowered to room temperature, and then transported to the rolling unit for heating again to 1200 ° C for rolling. The huge energy loss in the middle can be imagined. Continuous casting and rolling, thin slab casting can be directly rolled, both to avoid energy loss and give full play to the process characteristics, the development of appropriate low-cost high-performance steel, with a simple process, low investment, short production cycle, Low energy consumption advantages.
