查看更多>>摘要：Through the use of a new tundish steel level sensingsystem combined with an automatic control strategy, it has becomepossible to drain the tundish to a very low level with good safety andrepeatability. This has resulted in increased yield of cast slab fromliquid steel and has reduced the strand length scrapped anddowngraded from grade changes.
查看更多>>摘要：A new type of tundish heater, N2 Jet Heater, has beendeveloped by the authors so as to keep the inside of vessel hot andinert in the cyclic use operation of hot tundish. The system, anapplication of storage type heat exchanger, provides the jet stream ofnitrogen gas heated up to 1500℃ (2732oF) into the tundish in orderto maintain the non-oxidizing atmosphere.

查看更多>>摘要：In previous publications the author developed a robustand reliable algorithm for solving (k-?) finite element models ofturbulent flows [1-5].In the present paper, the developed analysis capability isapplied to the analysis of :(i) The submerged entry nozzle (SEN) in the mold of a continuous caster round.(ii) the tundish of a continuous casting installation.
查看更多>>摘要：Technique for preventing transverse cracks incontinuously cast slabs by microstructure control are investigated.The cracks are well-known to follow the austenite grain boundariesadorned with film-like ferrite.
查看更多>>摘要：Quality of continuous cast steel has been improved bycarrying out an integrated analysis of steel casting and slab formation.Operational parameters of steel casting on the #1 slab continuouscasting machine (SCC) at China steel corporation have been analyzedin this study.
