The method to solve the shrinkage defects of castings is:
(1) Fast solidification is carried out in the thick and hot joints
of machine tool castings, artificially causing the basic balance of
temperature field in all parts of machine tool castings. Use inside
and outside cold iron, local use heat storage zirconium sand,
chrome iron ore or special coating.
(2) Reasonable process design. The inner gate is located at the
relative thin wall of the machine tool casting. So that the
earliest into the thick wall of the metal liquid solidification
first, after the solidification of the thin wall, so that the basic
equilibrium solidification. For machine tool castings with uniform
wall thickness, multiple inner sprue and air outlet are used. Many
inner sprue, scattered and evenly distributed, so that the overall
heat balance. The air outlet is thin and many, that is, the exhaust
is unobstructed and plays a role in heat dissipation.
(3) Change the position of the inner gate
(4) Choose large heat storage modeling materials, which is very
important for the production of anti-wear products with lost mold!
Chromite ore to replace quartz sand and other small heat storage of
other sand, will achieve good results, casting microseismic better!
(5) Low temperature fast burning, open casting system. The liquid
metal fills the mold quickly, smoothly and evenly. It depends on
the circumstances.
(6) The machine tool casting strength of ductile iron is large, the
surface hardness is ≧90, and the rigidity of the sand box is large,
which is beneficial to eliminate shrinkage and loosening.
(7) When the riser is needed, move the hot riser first and leave
the hot joint. If the riser is placed on the hot joint, the size of
the riser will be increased to form "heating on heat". Do not do
well, not only shrink loose difficult to remove, but also produce
concentrated shrinkage, and reduce the production rate of the
process.
(8) Casting tilt placement and alloying, both benefit. Eliminating
shrinkage defects of machine tool castings is a complex process of
recognition and implementation. Based on the principle of "thermal
balance", scientific analysis should be made on Ju casting,
reasonable process plan should be formulated, suitable molding
materials, tooling and correct operation should be selected and
standardized. Then the shrinkage defects of any machine tool
castings can be solved.
