摘要
在双碳政策背景下,众多钢铁企业与科研院所积极开展低成本、高效率、环保型钢铁生产技术。铸坯火焰切割作为连铸生产的配套工序之一,受到了众多企业和研究人员的关注。高效节能的切割技术与环保的切割方式将是未来火焰切割发展的主要方向。基于现实需求,归纳总结了火焰切割中不同燃烧介质的切割原理,对比分析了不同切割介质切割成本、切割质量(切割缝隙、切割面平整度和挂渣量)、切割效率,综述了国内外钢铁企业、科研院所在连铸坯火焰切割方面的研究进展。并在此基础上,结合笔者团队研发的智控氢氧切割技术指出了当前铸坯氢氧火焰切割存在的不足与未来发展趋势。
Under the background of the dual carbon policy,enterprises,and scientific research institutes actively carry out low-cost,high-efficiency,and environmentally friendly steel preparation technology.As one of the supporting processes of continuous casting production,cast billets flame cutting has attracted the attention of many enterprises and researchers.Energy-efficient cutting technology and environmentally friendly cutting methods will be the main direction of future flame-cutting development.Based on the actual demand,the cutting principle of flame cutting different combustion media was summarized,the cutting costs,cutting quality(cutting gap,cutting surface flatness,and dross amount),and cutting efficiency of different cutting media were comparatively analysed,and the research progress of flame cutting of continuous casting billet in iron and steel enterprises and scientific research institutes at domestic and international was summarized.On this basis,combined with the intelligent control hydrogen oxygen cutting technology developed by the author's team,pointed out the shortcomings of the current flame cutting and the future development trend are pointed out.
