Analysis on Long Campaign-oriented Use,Maintenance and Structure Optimization of Copper Cooling Stave
The use and maintenance experience for long campaign of Shougang BF copper cooling stave is summarized mainly as effective control of the cooling water temperature,flowrate,pressure,effective control of harmful elements brought to the furnace and effective control of the edge gas flow,etc.In addition,special maintenance is also required after furnace blow off for medium and long term or blow down with stockline lowering,so as to ensure long-term stable and safe operation of the copper cooling stave.To prevent the risks of hot surface wearing and deformation of the copper cooling stave along with its long-term service,structure optimization of the cooling stave,such as inserting the armor into the stave hot surface,and re-inforcement of the stave body,can greatly improve the stave wear resistance and slag deposit behavior,enhance its deforma-tion resistance,and sequentially,prolong the service life under abnormal working conditions.It is believed that stable and smooth running of the blast furnace can be ensured so long as the copper cooling staves are properly design,used and main-tained,and the furnace can hit the campaign target of over one generation consequently.
