摘要

从特厚板坯料制造的角度,综述了海洋平台用齿条钢在国内外执行的标准及生产现状,分析了特厚板坯料生产技术及其难点。在此基础上,介绍了中冶京诚顺序凝固水冷模铸技术及中试结果,并采用仿真手段,预测了采用水冷模铸技术生产齿条钢坯料的可行性。仿真结果表明,采用顺序凝固的水冷模铸技术能够制造大单重高品质齿条钢坯料,为齿条钢坯料生产探索了一条兼具经济性和实用性的工艺方法。

Abstract

In the current study,the standard and production status of rack steel for offshore platform at home and abroad were described from the view of manufacturing of extra-thick plate blanks,and the production technology and difficulties of the extra-thick plate blanks were analyzed. Based on this,the water-cooled mould casting technology with sequential solidification and the result of pilot test were introduced,and the feasibility of casting plate blanks of rack steel with water-cooled mould casting technology was predicted by simulation. The simulation results show that the rack steel plate blanks of large piece weight and high quality can be generated by water-cooled mould casting technology with sequential solidification,which explores a economical and practical process for producing rack steel plate blanks.
