It was found that the main causes of the breakage are the unreasonable design of cooling s stem, low cooling intensit , defective stave and uncontrolled w ater qualit . Several measures w ere taken to restore the function of stave, such as using miniature cooler, rebuilding the stave and external watering, and good results were thus achieved somewhat . To remove thoroughl the hidden perils of the breakage of w ater pipe for stave, the cooling staves in the sections S3 and S4 w ere quickl and successfull replaced integrall , thus improving the furnace conditions greatl . The BF then returned to its normal productivit ver soon w ith a foundation laid dow n for its future production and prolonged s
