Inorganic acid and water softening agent (such as trisodium phosphate) are added in circulation water of blast furnace to control its pH value to be 7.0-8.5. The carbonate in the said water is converted into salt of inorganic acid while CO2 is released. The said salt of inorganic acid reacts with water softening agent to form phosphate partially to be deposited. Compared with existing process using antiscale, it features that the combination of cations and anions in circulation water is changed, that is, from carbonate type to inorganic acid salt type, to increase dissolvability and it has better anticorrosion and antiscaling effect and low cost.
