Abstract
The ladle and product analysis methods of correspondent industrial standards about chemical compositions of heavy forgings for 200MW power station equipment and below are compared,and their development history is reviewed in detail.A rapid pretreatment for multi-element contents determination of carbon and middle-low alloy steels by ICP-AES is further investigated in experiments.ICP-AES is also proposed as practical product analysis,and is expanded.SD-AES is proposed as a preferred choice of the industrial standards for ladle and product analysis.The methods are applied to routine production and inspection of heavy forgings,and are valuable in the revision of the industrial standards.关键词
