摘　　要：目前韩国钢铁巨头浦项制铁已经开发出板式换热器专用高加工性钛板产品,为了让板式换热器用钛板材具备冲压成型性,需要对其化学成分和制造工艺进行优化。为了确保成品的材质,冷轧板材通过间歇式退火或者连续退火的方式等再结晶退火工艺,并在此工艺中优化温度及模式等退火条件,控制材质与晶粒度,以获得高加工性的材质。South Korean steel giant POSCO has developed titanium plate with high workability for plate heat exchanger. In order to endow the titanium plate with press-formability, its chemical composition and manufacture process needs to be optimized. To ensure the quality of finished product, the cold rolling plate must be processed with recrystallized anneal techniques. To be specific, it can be realized by means of periodic or continuous anneal. Besides, the anneal parameters during this process must be controlled, such as the temperature or mode, to ensure the quality and grain fineness, then high workability could be obtained.
