Production Practice of Long-term Use of Water Quenching Coke in Daye Special Steel No.2 Blast Furnace
This paper summarizes the production practice of long-term use of water quenched coke in the No.2 blast furnace of Daye Special Steel.In response to the problems caused by significant fluctuations in moisture content and unstable quality during the use of water quenched coke,such as low temperature of blast furnace raw gas,large temperature fluctuations,zinc and alkali accumulation,and deterioration of furnace working conditions,the coordination of the iron front system and internal operational adjustments are carried out to ensure stable furnace conditions during the use of water quenched coke.This has created conditions for the rapid recovery of various parameters of the blast furnace after direct supply of dry quenching coke.
