No. 1 Furnace Air Preheater Renovation Project of Meigang 1422 Line
Shanghai Meishan Iron and Steel Co., Ltd. Hot Rolling Plant 1422mm Hot Rolling Furnace No.1 was put into operation in November 1993, and completed the technical transformation of combustion and cooling system in 2009. The fuel of the furnace is high-coke mixed gas, and regular burners are used for heating and continuous combustion control. The heating furnace is a walking beam heating furnace, and the furnace type is a three-stage heating side-to-side walking beam heating furnace. The heating furnace is divided into preheating section, heating section, heating section and soaking section along the furnace length from the charging end to the discharging end. In order to fully and effectively recover the waste heat of flue gas, a tubular air preheater is set in the flue.
