CAP1400核电厂主管道112吨电渣锭研制

Development of 112 t ESR Ingot for CAP1400 Main Pipe

文章简述了在世界上首次生产CAP1400主管道用SA376 TP316LN 112 t电渣锭的关键技术和取得的成果,指出生产CAP1400主管道锻件必须采用电渣锭,电渣重熔的关键是有效保证超低碳、氮含量、高纯净度和高均匀性。

This paper describes the key techniques and results of SA376 TP316LN 112t ESR ingot produced for the first time in the world. Points out, it must use the ESR ingots to produce CAP1400 main pipe forgings, and effective guarantee of ultralow C, N contents, high cleanliness and high homogeneity is a key during ESR.
