钢丝采用5～8％聚丙烯酸钠溶液淬火后,强度比皂液淬火高50牛/毫米~2,弯曲次数高3次左右,接近铅浴的中间水平;热处理和拉拔过程中的脆断明显减少,通条性能提高,钢丝的综合机械性能优于皂液,合格率稳定,且可处理含锰量高达0.8％的盘条。 After the steel wire was quenched with 5 to 8% sodium polyacrylate solution, its strength was 50N / mm2 higher than that of the soap solution, the number of bending times was about 3 times, which was close to the middle level of the lead bath. The brittle fracture during heat treatment and drawing was obvious Reduce, pass the bar performance, the overall mechanical properties of steel wire is better than the soap, the pass rate is stable, and can handle the manganese content of up to 0.8% of the wire rod.
