Shelling mould casting furnace bar

Ductile cast iron cast iron strength, plasticity and elastic mold are better than gray cast iron, wear resistance is twice as good as gray cast iron. Mining machinery water glass casting thickness changes have little effect on the mechanical properties, but the vibration resistance is lower than gray cast iron.

Ductile iron cast iron, although sensitive to the cooling rate, but due to the thermal stability, high temperature bearing capacity, can be used for the manufacture of between 300-4000. ℃ parts work in the environment. Its mechanical properties are less affected by changes in composition, so the yield is higher than other cast iron materials.

Ductile iron castings are generally designed into a thin and uniform structure, try to avoid thick sections, because the volume shrinkage is large, the line shrinkage is small, easy to produce shrinkage loosening and casting defects. 2. cast steel containing carbon accounted for 2. carbon content accounted for less than 0 of the iron-carbon alloy materials 11% below .2% belong to low carbon steel, 0.2% to 0. low carbon steel between 5%, above 0%. Medium carbon steel belongs to 5%.

In addition, there are high-alloy and medium-carbon steels. Cast steel materials have high comprehensive mechanical properties, stainless steel clad sand casting tensile strength and compressive strength is basically very high, thickness changes on the mechanical properties of the impact is small, low seismic capacity.
