唐钢二铁厂2号高炉于1996年7月进行了中修,重点对炉体软水密闭循环冷却系统进行了改进:①提高冷却壁的铸造质量;②改进冷却工艺,便于系统的补水、检漏和排气。高炉中修投产后,加强了对有关冷却参数如水温差和热负荷的管理,冷却系统运行良好。 No.2 blast furnace of Tangsteel No.2 Ironmaking Plant was undergoing major repair in July 1996. The improvement of the closed loop cooling system of soft water furnace was mainly focused on: (1) improving the casting quality of the stave; (2) improving the cooling process to facilitate the recharging of the system; Leakage and exhaust. After blast furnace repair put into production, to strengthen the management of cooling parameters such as water temperature difference and heat load, the cooling system is running well.
