Differences Between Forged And Cast Hose Coupling
Differences Between Forged And Cast Hose Coupling
Generally speaking, the mechanical properties of castings are lower than those of forgings of the same material. In addition,
the forging process can ensure the continuity of the metal fiber structure, make the fiber structure of the forging consistent
with the shape of the forging, and the metal streamline is complete, which can ensure the parts have good mechanical
properties and long service life. Precision die forging and cold extrusion are used. Forgings produced by warm extrusion
and other processes are unmatched by castings.
After forging, metal can improve its microstructure and mechanical properties. The metal fiber structure is deformed
and recrystallized by the forging method due to the deformation and recrystallization of the metal, so that the original
coarse dendrites and columnar grains become an equiaxed recrystallized structure with finer grains and uniform size,
which causes the original segregation in the steel ingot. , Looseness, porosity, slag inclusion and other compaction and
welding, its structure becomes tighter, improving the metal's plasticity and mechanical properties.
Casting is a piece made by casting. Casting is a piece that has a mold or a model and pours molten steel into it.
The process of smelting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling and
solidifying and finishing, a casting (part or blank) with a predetermined shape, size and performance is obtained.
A forging machine is used to apply pressure to a metal blank to plastically deform it to obtain a processing method
of forgings with certain mechanical properties, a certain shape and size.
