Application | Conehead is the components of bolt ball steel truss,welded to the end of steel pipe,the screw of high strength bolt goes through the bottom hole into bolt ball,nut is in conehead,the same function with “seal board”,when steel pipe diameter is small to use “seal board”,when steel pipe diameter is big to use”conehead that can avoid from collide with pipe steel. |

Process procedure:
Forging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Heating(Furnace temperture test) → Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment
