Mandrel bar plays a crucial role in producing large diameter
seamless pipes in modern industries. In production line, it have
to bear
strong and complicate stretch, compressing touching stress and
high temperature cold-hot yield stress under high speed
cycling.
Under these circumstance, chemical components, mechanical
propertied, no-metallic inclusion, grain size, microstructure,
ultrasonic test, size precision, surface finish, all these
factories of steel are required very strictly. Mandrel bar is
made from H*3(4Cr5MoSiV1).
With annual output of *5 thousand tons, its quality and service
life have reached to world level of that.
Our company is capable of producing a series of mandrel, such as
MPM, PQF, FQM, with the diameter of Φ*0~**0mm, the length of
*********0mm.
Equipment advantage: steel making (EBT+LF(VD)+ESR)-forging(formed
by hydraulic press machine + forged by rotary forging
machine)-annealing-rough machining –magnetic test-heat
treatment-ultrasonic test-finish machining-chrome plating-thread
phosphating.
