S—135钢板热轧工艺研究

Hot Rolling Process Study of S-135 Steel Plate

S—135钢板是水电站用高强耐磨不锈钢板,既要求强度高、韧性好,又要求耐磨、耐蚀性强,生产难度较大。除我厂外,目前国内尚无其它厂家能够生产这种钢板。该钢板在加热轧制,冷却过程中要解决很多技术难点。我们通过采用特殊的控制轧制和控制冷却工艺,很好地解决了诸多技术难点,使S—135钢板的开发研制取得了成功。为电站用高强度耐磨不锈钢生产提供了宝贵的经验,也为控制轧制及控制冷却技术在中板生产行业的应用起到了积极的推动作用。

S-135 steel plate is high strength, wear resistant stainless steel used in hydro power sta-tion. It requires high strength. good toughness as well as good wear resistance and corrosion resistance. Therefore,its production is difficult. At present ,no other plants at home except our plant can produce such plate. Many technically difficult points have to be solved during heating,rolling and cooling process of the plate. We have well solved many technically difficult points by means of special controlled rolling and con-trolled cooling process so that success has been achieved in development and research of S-135 steel plate. It has provided valuable experience for the production of high strength,wear resistant stainless steel used in power station,and also played an active promoting role in the application of controlled rolling and controlled cooling technology in the production of medium plate.
