合成氨用变换炉封头成型技术

Molding Technology of Compounding Ammonia Converter Head

变换炉的封头通常为球缺式,15CrMo类材质,厚度50～90 mm。其成型的方式可采用分两半下料,拼焊后整体热冲压成半球,调质处理,气割开孔、去环缝余量并机械加工。本文对此种成型方式进行了深入的研究。

Converter head is usually a segment type,15CrMo type material,and the thickness is 50 to 90 mm.The forming mode can adopt two valve cutting,welding and overall hot stamping into hemisphere,quenching and tempering,gas hole,to ring seam allowances and mechanical processing.This paper studied the forming way.
