摘要
通过优化,将换热管板两侧半圆弧形的盘管改成圆管结构,组成整体换热板,换热管分别采用180°圆弯头90°圆弯头焊接成形。管板与主轴的焊接过程中,采用焊后退火热处理,防止冷裂纹,能达到良好的脱氢效果。
Change two flanks semicircle coil to circular tube by optimizing the heat exchange plate,compose the whole of heat exchange plate. The heat exchange coil are formed as one body by 180°round elbow and 90°round elbow. In the process of weld plate on axle,Using annealing after weld to prevent cold crack,To achieved the well effect of remove hydrogen.
