摘　　要：介绍了新余钢铁有限责任公司试制开发D36高强度船板的主要技术要求和工艺路线.因轧机各项力能参数偏小,在开发D36高强度船板过程中,出现了厚度偏差改判和钢板可焊性不理想现象.通过采取压下分配的调整、成品目标厚度及控制范围的平移和微Ti处理等措施,较好地解决了上述问题,提高了D36钢板的综合性能和可焊性.The main specification and process route during production and exploitation of D36 high-strength ship plate steel in Xunyu Iron and Steel Co., Ltd. were introduced. During the exploitation of D36 high-strength ship steel, thickness deviation changing and bad plate weldability were risen by less functional parameters of the rolling mill. The over-all properties and weldability of the D36 plate were preferably solved and improved by the adjustment of depressed allocation, the translation of product objective thickness and control range, and micro-Ti treatment.
