  我们都知道,辽宁舰前身是“瓦良格号”,碍于乌克兰的经济发展受阻,所以瓦良格号并没有建造完成,运回中国后就进入了大连造船厂进行改造。要想完成改造任务,对技术的要求是非常高的。我国不想被西方国家“卡脖子”,所以这项改造任务,中国完全是靠自己完成的,由于瓦良格号常年泡在水里,内部设备和外部钢材都需要进行更换,经过计算,要想完成修复任务,至少需要几百吨对称球扁钢,无缝钢管

  在两个集团的努力下,中国终于研发出与美国福特级相差不多的无缝钢管钢材,看到中国取得的成绩后,西方国家也闭嘴了。在为国产航母供应钢材的任务中,鞍钢仅用一年就完成了过去十年的特种钢产量,在鞍钢的帮助下,国产航母的建造速度也大大加快了,从改造到正式交付只用了7年,如果不是鞍钢的付出,辽宁舰不可能这么快服役。
