德胜钒钛1250m^3高炉低品位高钒钛矿冶炼降焦比实践

Henderson High Vanadium Titanium 1250 m^3 Blast Furnace Low Grade Vanadium Titanium Ore Smelting Coke Rate Reduction Practice

德胜钒钛1250m^3高炉2010年投产,20个风口送风,两个铁口,采用PW无料钟炉顶上料、软水密闭循环系统、水粹渣处理系统等技术。德胜钒钛1250m^3高炉在降焦比攻关过程中,从精料入炉、强化高炉操作和管理及设备改造等方面采取措施,成功突破了低品位高钒钛磁铁矿冶炼高焦比的瓶颈,解决冶炼过程中渣比高、脱硫难、炉渣黏的难点,开拓了一条小中型高炉降本的新道路。攻关前后指标对比,提高煤比达57kg/tFe,降低焦比142kg/tFe。

DE-vanadium titanium 1250 m3 blast supply, two iron mouth. Use PW no bell roof, furnace put into production in 2010, 20 tuyere air water, soft water closed circulation system of slag processing technology such as essence. DE sheng vanadium titanium 1250 m3 blast furnace in the process of coke rate reduction research, through concentrate charging, strengthening blast furnace operation and management and equipment modification, etc. Successfully broke through the low grade high vanadium titanium magnetite smelting high coke rate of bottleneck, solve in the process of smelting slag is more difficult than high, desulfurization, slag adhesion difficulties, opens up a new path of small to medium sized blast furnace authors. Research indica- tors before and after contrast, increase up to 57 kg/tfe coal ratio, reduce coke rate of 142 kg/tfe.
