摘　　要：铜及铜合金具有优良的导电导热性能,其在钢铁冶炼过程中的连铸结晶器上起着举足轻重的关键作用。然而结晶器所在的恶劣服役条件却限制了其性能的发挥,较常见的损耗形式为结晶器铜板内表面弯月面处的热裂纹及结晶器铜板下部的摩擦磨损,这些损耗形式在一定程度上大大缩短了结晶器的使用寿命,针对此现象综述了国内外不同表面改性强化技术在结晶器铜板上的应用,通过不同表面改性强化处理,可提高结晶器铜板耐磨性、耐热冲击及耐腐蚀性能,从而提高铸坯质量、延长结晶器使用寿命及降低生产成本的目的。Copper and copper alloys have excellent thermal and conductivity properties, which plays an important role m the contmuous casting mold in the steel smelting process. However, adverse service conditions where the mould in has limited the performance of the copper, the more common loss is the thermal cracking at meniscus and friction and wear in the lower portion of the mould copper plate, these losses shorten the life of the mould to some extent. For this phenomenon, different surface modification technologies on strengthening domestic of mould copper at home and abroad were summarized, through different surface modification enhanced treatment can improve the abrasion resistance, thermal shock resistance and corrosion resistance the service life of the mold and reduce production costs. of mold copper, thereby increasing the slab quality and prolong the service life of the mold and reduce production costs.
