| Abstract: | The on-line processing of blast furnace closed soft water system cleaning and pre-membrane technology were adopted in the paper. The technology is used to slove the problems of long shutdown time, internal circulation system equipment and pipeline scaling and internal corrosion. The solution of implementing cleaning pre-membrane technology is determined . It is proved that the effect of the blast furnace closed soft water system on line cleaning and prefilming is good. The corrosion rate of carbon steel hanging piece is O. 777 6 g/m^2 · h and the passivation film is 18.72 s ,which achieve the desired requirements. |
