摘要
针对核电关键设备广泛采用的Z2CN19-10(N)超厚超重板材,设计了合理的生产工艺路径,研究了相关的成分设计、模铸工艺、锻造工艺、表面质量控制和板形控制等关键生产技术,成功开发了超厚超重核电板材。成品板材的全面评价结果表明,板材整体的晶粒度、夹杂物控制水平、力学性能、耐腐蚀性能和无损探伤性能完全满足核电行业广泛采用的RCC-M标准的各项指标要求。
Z2CN19-10（N）,a type of austenitic stainless steel ultra-thick and ultra-heavy plate,has been widely used to manufacture key equipment of the nuclear power.After the proper production technology route was determined and some corresponding key techniques were investigated,which include alloy design,mould casting,forging technique,surface quality control and shape control,the Z2CN19-10（N）ultra-heavy plate was developed successfully in Baosteel.The results of evaluation for the plate＇s performances show that the grain size,inclusion control level,mechanical properties,corrosion-resistance properties and nondestructive evaluation properties of the ultra-heavy plate can satisfy each index demand of the RCC-M criteria,which is extensively accepted in the nuclear power industries.
