I.Intro:Based on horizontal continuous casting for cast iron profile(dense bar),we've developed new casting tech ‘Vertical upward continuous casting’ in 2006, by using this tech we manufactured new kind
of cast iron profiles ---Cast Iron Hollow Bar , which have been tested by chinese authority sector in mechanical industry and proved that the quality is much better than traditional sand-casting or
centrifugal casting profiles . Our advantages including high density,zero deficiency,close final shape(tube),superb wear resistance,high purity,excellent machinability and fatigue strength etc.
II.Material:we could supply the continuous cast iron profile as follow:
1.Ductile Cast Iron Pipe/bar(ISO:400-18/500-7/600-3/700-2/800-1) ---spheroidization rate 90%,ball diameter 7~8,ball number 400~600/mm2 ---compare sand casting, at same strength, elongation increase 50~100%2.ADI(Austempered Ductile Iron) ---σb≥1200Μpa,δ≥2%,ak≥35J/mm23.Gray Cast Iron Pipe/bar(ISO:150/200/250/300/350) ---Matrix: ferrite+pearlite ---σb=150-380 Mpa, HB=150-240, E=1.1-1.7*105Mpa4. Alloy Gray Cast Iron Pipe/bar --CrNiMo Cast Iron--CrMoCu Cast Iron--High Nb Cast Iron--VNb Cast Iron --High B Cast Iron--High P Cast Iron--High Ni Cast Iron...
III. Specification: ---Cross-Section:Round,Rectangle,Elliptic,Hexagonal ---OD:60-320mm,Thickness:8-35mm
Our profiles could be widely used in mechanical industries,such as railway vehicle, oil machine,engineering machine,auto parts,compressor, hydraulic and pneumatics,chemical pump, machine
tool,metallurgical equipment etc.Meantime, we also supply related products in blank, such as cylinder liner,piston ring,ADI bushing,sealing ring,suction pipe etc. By using our profile, the working
life of our products will be 5 times than sand casting,and no pore,sonim... Adapt to strict requirments in precise manufacturing.
