Description:
The full name of pipe mould is centrifugal ductile iron pipe mould,
which is used for casting ductile iron pipes. It’s large
equipment for producing ductile iron pipes on the machine of
centrifugal pipe-casting. In the manufacturing process of ductile
iron pipe, pipe mould is mounted on a centrifugal casting machine
with high-speed rotation to cast iron pipe. It belongs to the
industrial consumables.
Owing to poor working conditions, such as high-speed
rotation, great centrifugal force, under alternating stress and
cold outside and hot inside in the process of using pipe mould, the
die forging quality is directly related to its life -- numbers of
extubation.
Our company provides alloy steel pipe mould with excellent
mechanism performance, which can have a variety of special
properties, such as wear resistance, high and low temperature
resistance, corrosion resistance and so on.
The materials: 21CrMo10, 20CrMo, 30CrMo, 42CrMo,
35CrMo, etc. are mostly used for the forged centrifugal casting
pipe mould. It is made from forging, normalizing, formed with
quenching and tempering treatment.
Different ways of machining process are followed in
light of different specifications of the pipe mould, in order to
lower its cost.
A) For small-caliber pipe mould, using solid forgings
for the blank, and adopting deep-hole drilling, boring hole for
machining.
B) For medium-caliber pipe mould, using solid forgings
for the blank, employing technological methods of jacking and
boring hole.
C) For large-caliber pipe mould, using hollow
forgings, ability to complete all the machining for outer circle of
the inner hole disposably. It not only improves the production
efficiency, but also can obtain good coaxiality.
Production process: steel ingot -- forging -- rough
machining -- UT -- boring -- QT -- the 2nd rough machining -- hole
enlarging -- aging -- lightly boring -- oiling -- packaging --
