苏联波多尔斯克机械厂与巴頓电焊研究所用板極电渣焊焊成制氧和制氮机上的1X18H9T鋼的鍛造法兰盘。母材的化学成分如下:0.10％C;1.10％Mn;0.54％Si;17.75％Cr;9.3％Ni;0.51％Ti;0.018％S;0.028％P。鍛件經过热处理——奥氏体化淬火(加热到1100℃水冷)。用电渣焊連接的法兰毛坯由二部分或四部分組成。整个法兰盘的外径为1550～2720公厘,寬120～200公厘,高150～230公厘。鍛件重0.5～2吨。按照技
Forging flange of 1X18H9T steel on oxygen generator and nitrogen generator by plate electrode electroslag welding with the Soviet Union Pottolsk Machinery Factory and Barton Welding Research Institute. The base metal has the following chemical composition: 0.10% C; 1.10% Mn; 0.54% Si; 17.75% Cr; 9.3% Ni; 0.51% Ti; 0.018% S; 0.028% P. Forgings after heat treatment - austenitizing quenching (heated to 1100 ℃ water cooling). The flange blank connected by electroslag welding consists of two parts or four parts. The entire flange of the outer diameter of 1550 ~ 2720 mm, 120 to 200 mm wide and 150 to 230 mm high. Forging heavy 0.5 to 2 tons. Follow the technique
