【Abstract】 There are some technology problems such as the con t rol of ring header’s roundness and flatness, the control of ring header’s join ting distortion, the overmeasures for ring header’s hydraulic pressure test in two recently manufactured CFB boilers in SBWL. It appears some new problems in t he 517t/h CFB boiler newly manufactured by SBWL, such as lackness of assemble si tes in workshop. This paper introduce some measures taken in the newly manufactu red 517t/h CFB boiler based on these problems and do some analysis, discussions, brief summaries on manufacture technology of ring header.更多还原
