| Abstract: | The hazards from Fe￣(2+) in the phosphorization solution for cold-drawn steel tubes and elements responsible therefor are investigated,and mechanism concerning depression of the said Fe￣(2+)described.Experiments upon depression of Fe￣(2+) in the phosphorization solution with NaClO_3 were carried out, which led to the conclusion that adding NaClO_3 into the solution at the concentration by weight of 0.5g/L could produce effective depression, hence increased economy.Also introduced are the key points of the operation. |
