65m~3一水糖结晶器的φ3170mm冷却盘是白δ=3mm不锈钢上、下板盘和夹在板盘中间的57根挡水隔板组成的具有长达88m水冷循环系统的夹芯转盘,其平面度<3mm,径向偏差<3mm,表面粗糙度8～10μm,最后作0.25MPa水密试验.原设计的T形挡水板应用电弧焊焊接组合,再用电弧焊焊于上下板盘上,然后用电弧塞焊组合两板盘。此种设计为加工制作造成巨大困难。经研究,将T型焊接件改为匚型冲压件;将板盘折边玫为拼焊包边;将匚形件与板盘的电弧焊组装改为点焊。此举技术、经济效益显著。.
The φ3170mm cooling disc of 65m ~ 3 water sugar mold is a sandwich carousel with up to 88m water cooling circulation system composed of upper and lower plates of white δ = 3mm and 57 water-blocking partitions sandwiched between plates. Its flatness <3mm, radial deviation <3mm, surface roughness 8 ~ 10μm, and finally 0.25MPa watertight test. The original design of T-shaped flap welding arc welding combination, and then arc welding on the plate on the plate , Then use arc plug welding combination of two plate. Such a design for processing caused great difficulties. After the study, the T-type welded pieces into stamping parts; the plate folded rose Mei Wrap the edge; the stirrup and the plate arc welding assembly to spot welding. The move of technology, significant economic benefits. .
