【Abstract】 A new technology for improving hot blast temperature and decreasing fuel consumption with high emissivity coating on the regen-eratorof blast furnace(BF) hot stove were introduced.Theoretical analysis and experimental results showed that the high emissivity coating speeds up theheat-absorption and heat release process,strengthensheat transfer by radiationand heat conduction in the regenerator,improves heat transfer efficiency and the blast temperature.Application of coating in hot stoves of 350 m3 BF indicated that the coating makes the blast temperature increase 57℃.It can be concluded that preparation of coating on heat regenerator surface provides a new practical and operable technology for energy saving in steel industry.更多还原
