合成氨装置开工加热炉盘管制造技术改进与创新

Technological Improvement and Innovation of Coil Manufacturing in Starts Heating Furnace of Ammonia Plant

针对合成开工热炉加热盘管工作压力大(12MPa),操作温度高(565℃),材质特殊,制作难度大、成本高等特点。改进制造工艺,变单圈盘制、单圈焊接为多圈绕制、整体一次性组焊。设计专用绕管、螺距定位、输送导向及焊接背氩工装。极大的改善了加工工艺,提高了产品质量,降低了制造成本。

Direct at the starts heating furnace is running under the high pressure（〉12.025mpa）, working at high temperature（565 ℃ ）, using special material and difficult manufacturing and high cost. So we change and develop the manufacturing process. We use many laps coiled and welded once time to instead of one lap coiled and welded many times and design dedicated machine and frock to winding, pitch orientation, convey guiding argon arc welding. This is larger improve processing technic and quality of the product and more reduce the produce cost.
