本文总结了首钢京唐钢铁公司300t铁水捞渣机应用32个月以来的应用情况,对比了捞渣机与扒渣机,1号捞渣机与2号捞渣机之间的经济、技术指标,并对捞渣机在未来钢铁“连续高效、低耗少排”的生产要求趋势下的作用进行了展望。
Development of Combined Level 2 System and Property Prediction Model for Production Stability and Ne
This paper first outlines Level 2 System with metallurgical microstructure model.It then discusses application of new-generation Level 2 and property prediction software in the new product development
Currently,approx.95% of steel are produced by means of continuous casting,and the trend is rising,commonly using continuous slab casters and CSP(E) plants.In the field of conventional continuous casti
Milestones in continuous casting were set by the SMS group and its predecessor companies (Schloemann,Concast and Mannesmann Demag) and testify to 50 years of leadership in continuous casting.Being a f
Hard-to-design roll passes contain large number of constrains such as fewest passes,smallest groove-width,lowest roll diameter,and most types/numbers of products from fewest billet sizes.Extra complex
Over the last quarter of a century CSP(R) technology has built up a very impressive standing worldwide.The special CSP(R) process conditions make the production of high value-added steel grades at low
