铜钢复合板是制造高能加速器直线加速器腔体的关键材料。由于铜钢间熔点差大,热胀性能不一致,而且要求板型大、精度高、铜钢贴合好,并须有良好可焊性与特殊物理性能,因此铜钢复合板的研制是一项技术难度较大的课题。为此,钢铁研究总院研究了铜钢复合板迭不同表面状态、组合方式、加热温度与轧制制度对铜钢贴合的影响,测定了不同温度下铜钢贴合临界变形量;选出了新型隔离剂;分析研究了铜钢复合界面的状态;并对铜钢复合板的可焊性及其焊接材料进行了研究。在此基础上,重庆钢铁公司和午阳钢铁公司进一步开展了工业试制,经过多次试验成功地轧制出大型铜钢复合板。
Copper-clad composite plate is the key material for the manufacture of high-energy accelerator linear accelerator cavity. Due to the large difference between the melting point of copper steel, thermal expansion inconsistent performance, but also requires a large plate, high precision, good fit copper, and must have good solderability and special physical properties, so the development of copper composite plate is a Difficult technical problems. For this reason, the Central Iron and Steel Research Institute of copper and steel composite plate Diego different surface conditions, combinations, heating temperature and rolling system on the impact of copper steel, measured at different temperatures of copper steel fitting critical deformation; selected A new type of release agent was obtained. The state of the copper-steel composite interface was analyzed. The weldability and welding material of the copper-steel composite plate were also studied. On this basis, Chongqing Iron and Steel Company and Wuyang Iron and Steel further carry out industrial trial production, after many successful trials rolling large copper clad steel plate.
