    雙相鋼在冷拔單體液壓支柱缸筒中的應用

    APPLICATION OF DUAL-PHASE STEEL TO MANUFACTURE OF COLD-DRAWN PIPES FOR ONE-PIECE HYDRAULIC PILLAR CYLINDER

    • 摘要: 介紹了雙相鋼的特征,分析了其性能優(yōu)良的原因,比較了10MnSi雙相鋼和27SiMn低合金高強度鋼的σ-ε曲線,鋼和冷拔管的機械性能及工藝性能等。結(jié)果表明,雙相鋼適合冷拔制造液壓支柱缸筒,其綜合經(jīng)濟效益較好。

       

      Abstract: Characteristics of the dual-phase steel are described;excellent properties of the said steel are investigated;σ-ε characteristic curve of the 10MnSi dual-phase steel is compared with that of the high strength, 27SiMn low alloy steel, also made are comparisons concerning mechnical properties and process performances between the said dual-phase steel and the pipe made thereof.Then, it is concluded that the said dual-phase steel is applicable for producing cold-drawn pipes for hydraulic pillar cylinder, which is economically profitable on a comprehensive basis.
