 As the main development program of China casting
industry, the development of ductile casting iron plate is a
very impressive their ears, ductile casting iron tablets for
casting industry in China's development is necessary, let's do a
quick rundown of ductile casting iron tablet related knowledge!
Ductile casting iron tablet consists of steel plate and box type
two kinds.
Ductile casting iron plate of the overall specifications largest
is 4 m x 8 m, ductile cast iron plate on the push table,
workpiece is smooth, no hair no hair acerbity feeling,
convenient measurement, in order to ensure accurate measurement
of ductile casting iron plate heat treatment is very important
for flat performance will produce very big effect, so using the
casting plate must choose economic meaning of cast iron
materials, the methods of aging treatment to eliminate the
residual stress of casting slab.
Ductile casting iron plate flatness is refers to the package in
the working face plate of the actual working face and the
distance of the minimum distance between two parallel plane, its
value can be according to the diagonal line method, the loop
method of the test results are \"base level transformation is
obtained. Ideals ductile casting iron plate on the surface of
the plane relative to the actual concrete bearing plays a
decisive role. Ideal for different azimuth plane and each point
on the surface of the actual distance is different. Machining of
micro quality refers to the processed profiles tiny peak valley
roughness spacing.
Ductile casting iron plate local error refers to the flat face
flatness machining quality. The coarse degree. Microstructure
are of good quality, resistance to wear, the service life of the
tablet. And face small local distortion is within the scope of
processing of uneven and deformation. This working face, a small
scale for small tablet is local position, on the tablet is the
local area.
Ductile iron castings is lighter, the weight of the tablet and
verification tool weight is, when it in different positions,
ductile cast iron tablets three pivot load balance changes,
resulting in contact deformation between the plate and
supporting.
Verification test sites should be considered when the stability
of the outside, also should pay attention to check the silent
tool quantity, should be increased if necessary auxiliary
support to enhance a tablet placed firmly. So inspection
personnel walk near the tablet, mobile verification tools on the
tablet, a variety of gravity, make splint space position change,
and make the measurement result is not reliable.
My company mainly produces ductile castings, castings, pump body
pump casing, impeller, alloy casting and other casting products.
