厚规格辊压用热镀锌高强钢的开发与性能研究

Development and Properties Research of Hot-dip Galvanizing high Strength Thick Plate for Roll Forming

利用改良森吉米尔法卧式退火炉设备特性,在低碳锰钢基础上适当添加微合金化元素Nb,成功开发出组织为铁素体和珠光体的厚规格热镀锌高强钢,该钢钢质纯净、晶粒细小、具有优良的冷成形性和良好的性能均匀性,成功应用于辊压成形机组的复杂零件制造。

Using improved Sendzimir coating process ,hot‐dip galvanizing high strength thick plate with a microstructure of perlite and ferrolite is successfully developed by adding appropriate Nb on the base of low carbon manganese steel .Owing to its pure materials ,fine grain size ,excellent cold forming perform‐ance and well homogenization ,the steel is used to make complex parts with roll forming equipment .
