Design on Closed Loop Soft Water Cooling System for Shougang Qiangang No.3 BF
Ability to improve cooling system, avoid untimely damage of BF lining and coolers, reduce maintenance frequency and prolong maintenance period during the furnace campaign, it is imperative for BF longevity. Describe development of cooling system, illustrate economic rationality and safe reliability of closed loop soft water cooling system, stress equipments, process, design, system measurement and control on closed loop soft water cooling system for Shougang Qiangang No.3 BF. Take full account of BF working condition, lining structure and corrosion mechanism, combine actual investment, choose advanced and rational coolers; develop segmentation design for cooling system, strengthen BF cooling effectively, boost system steering rate in order to reduce temperature of brick lining, prolong lifetime of brick lining, keep the lining integrity, maintain rational furnace profile, ensure BF production and longevity.
