摘要
以RAP400冷连轧中牌坊的加工为研究对象,阐述了牌坊需加工的位置、公差等要求,分析了牌坊加工的难点,包括降低中间部位的下挠、提高加工精度的措施等,然后阐述了牌坊加工的三要点,大平面加工、螺孔及精孔的加工,这些工作为轧机领域的制造提供一定借鉴。
Taking RAP400 memorial arch in the cold rolling process as research object,the machining location of the first elaborated memorial arch,tolerance and other requirements were illustrated,then the processing difficulty of the memorial arch was analyzed,including decreasing middle downwarping,improving machining precision, etc. ,and then the three points of memorial arch processing including large plane processing,the screw hole and fine processing were described,which can provide certain reference in the field of rolling mill in the future.
