Steel casting is an important casting process in our foundry. Deformation usually happened on finished steel castings. Then, what leads to the deformation of steel castings? Deformation defects happened frequently all through the casting processes. Mainly two factors result in the steel casting deformation defects.
In investment casting process,we often meet defects like gas cavity,sand inclusion,cold insulation,ect.Now we would like to talk about the effects of gas cavity on investment castings,which is caused as the gas is not timely escaped before crusts of liquid metal.
ue to the needs of various metal parts for industries,metal casting process was invented.We could make metal castings with different materials and structures.Normally,we could devided the casting process into investment casting and sand casting.Investment casting is mainly adopted in small precision metal parts.However,sand casting is mostly for larger parts.
We need to properly select optimal chemical composition to obtain a given organization for cast iron production,heat treatment is also an important way to further adjust and improve matrix structure in order to improve the performance.Cast iron heat treatment has some way with cast steel heat treatment,but also exist differences.Cast iron heat treatment generally could not improve the morphology and distribution of graphite in the original organization.
Investment casting process is commonly used for industry manufacturing.So what are the advantages of it?
To control the quality of our investment casting parts, our foundry is equiped with various inspection instruments.
