一、引言 《Palenting》钢丝是目前工业应用的高强度材料之一。这种材料系将高碳(0.6～0.85％C)钢奥氏体化后在其TTT图形珠光体鼻子稍下温度的铅浴中进行等温处理,再经深度冷拔加工,而获得高强度和足够高韧性的。目前,国内外Patenting钢丝生产工厂仍广泛采用铅浴等温处理。 然而,铅蒸汽及氧化铅(粉尘)具有很强的毒性,不采用特殊的防护措施,将会造成环境污染,而且消耗的金属铅是一种重要的战略物资。因此,Patenting钢丝不用铅浴进行热处理是钢丝行业的一项重要研究课题。
I. INTRODUCTION “Palenting” steel wire is one of the high strength materials for industrial applications. This material is high carbon (0.6 ~ 0.85% C) steel after austenitizing its TTT graph pearlite nose temperature is slightly lower in the lead bath for isothermal treatment, and then by deep drawing process to obtain high strength and High enough toughness. At present, the domestic and foreign Patenting steel production plant is still widely used lead-acid bath isothermal treatment. However, lead vapor and lead oxide (dust) are highly toxic and can cause environmental pollution without the use of special protective measures, and the consumed lead metal is an important strategic material. Therefore, Patenting wire without lead bath for heat treatment is an important research topic in wire industry.
