Development and application of a multi-graphite electrode DC plasma tundish heating
文献摘要：
The world's first three-graphite electrode direct current(DC)plasma heating system(2500 kW)was successfully put into production on the 50-t tundish of a two-strand slab caster.The single metallic torch plasma tundish heaters were reviewed.In addition,the induction heating system was also estimated.The three-graphite electrode DC plasma tundish heating(PTH)system does not require any electrode to be fitted to the tundish.Five electrodes can be used to realize uniform and fast heating of the six-strand tundish.Heating with high power can effectively eliminate the steep temperature drop of the molten steel in the tundish during ladle change-over.The system has turned out to be very reliable,simple,and main-tenance-free.The heating rate is high within 0.5 to 2.0℃/min.Some heats with ultra-low superheat(2.6-11.0℃)were observed,and the molten steels were successfully cast by the powerful heating capacity and good control performance of the system in the practical production.It can be concluded that continuous casting with superheat of 5-10℃ in the tundish was fully realistic with PTH.
