ZH70Q舞阳钢板定扎，有材质书和质量证明单保证原厂出产

1、牌号简介ZH70Q钢板属于高耐磨中碳铬钼齿条钢，是舞钢公司自主研发的高耐磨型齿条钢，主要用于制造海上风电安装平台的桩腿。ZH70Q钢板由舞阳钢厂生产，舞钢军工所承接。ZH70Q钢板中的Z是振华重工振的首字母，H则是华的首字母。70表示钢板的屈服强度是。2、用途：舞阳钢铁公司研制开发的ZH70Q钢板将批量应用于世界首创的新型“2500吨自升沉垫式海上风电安装平台”关键部位-升降平台桩腿的制造，ZH70Q钢板属于耐磨型中碳铬钼齿条钢 。ZH70Q钢板此次使用的厚度达到180mm。自升沉垫式海上风电安装平台又称“海上风电安装船”，主要用来进行海上风机、基础运输及安装施工，平台拥有四条桩腿，牢牢地插入海底，将船体支撑并固定，形成不受波浪影响的稳定平台，是我国海上风电作业从浅海走向近海的关键利器。3、执行标准：舞阳钢厂是生产国内海洋平台用钢的龙头企业，代表起草《自升式平台桩腿用钢板》标准，ZH70Q钢板的执行标准：WYJ(舞阳钢厂技术标准)。4、化学成分：牌号CSiMn .08-0.14≤0.50.4-0.8≤0.02≤0.012-2.50.9-1.1≤0.3≤0.0125、力学性能：屈服≤mm≥460≥440≥420≥400≥400≥380抗拉强度 伸长率≥17%冲击试验≥34J5、舞阳钢铁公司代表国家主持起草了《自升式平台桩腿用钢板》国家标准，自己研发生产的215mm齿条钢板为国内生产大厚度海洋平台用钢板之最，生产的、结束了我国海洋平台关键部位用钢长期依赖进口的历史。

6、河钢舞钢以满足高端客户差异化、个性化需求为己任，不断加大对市场、客户和产品的研究力度，在与“老朋友”振华重工无缝对接的过程中了解到，该客户志在打造海上风电领域的“海上巨无霸——“2500吨自升沉垫式海上风电安装平台”。由于该平台属世界首创，用钢技术要求很高，特别是关键部位用钢要求更高，全世界还没有企业生产过如此高难度的钢板。国内某知名特钢企业曾想揽下材料制造权，但最终因技术指标难以保证而放弃。

ZH70Q steel plate to high enum rack which is a high rack steel by used for pile legs of wind power .ZH70Q steel plate by Steel to .Z in ZH70Q steel plate is the of Heavy and H is the of Hua.70 that the yield of the steel plate is .

2. : The ZH70Q steel plate by Iron and Steel will be in to the of the pile leg of the the key part of the world's first new " pad wind power ". ZH70Q steel plate to the and rack steel.The of ZH70Q steel plate used this time is 180mm.

Since the heave pad wind power is also the "sea wind power " fan, used for sea and has four legs, into the of the sea, will and hull form is not by the wave of is China's wind from water to key tool.

5, Iron and Steel on of the to draft the " pile leg steel plate" the own and of 215mm rack steel plate for the of large of the steel plate for the most, the of ended China's in the key parts of the on of steel .

6, river steel to meet the as own duty, the study of and with "old " heavy in the of the that the to build wind power in the field of "sea big MAC -" 2500 tons from heave mat type wind power ". this is the first of its kind in the and the steel are very high, for the key no in the world has ever such a steel plate.A steel had to win the right to make but of the are to and give up.
