摘要
采用-50℃的15MnNiNbDR国产钢用于2 000 m3液氨球罐的制造,针对低温容器钢的特点,制定出了合理的焊接工艺,满足了液氨球罐焊接接头的低温冲击韧性要求。
15MnNiNbDR was to be used for 2 000 m^3 spherical tank at --50℃. During fabrication, appropriate welding procedure to meet the toughness requirement for low temperature impact test of welding joint on spherical tank was established.
