摘要
石横特殊钢厂采用LF21合金开发生产制氧设备用星形管,通过控制LF21合金的化学成分,制定合理的均匀化制度及挤压工艺制度,使产品质量符合GB6892-86要求。
LF21 alloy is developed to produce star form pipe used in oxygen making equipment in Shiheng special steel plant By controlling LF21 alloys composition,making reasonable system of homogenizing treatment and extrusion technology,the extrusion products quality is coincidence to GB6892-86 standard
