What is the difference between forging and casting? Uses, advantages and disadvantages?
Forging is a method of machining a metal blank by applying a press machine to produce a plastic deformation with a certain mechanical performance, a certain shape and sizeCasting - smelting metal, making mold, and pouring molten metal into the mold, after solidification, to obtain a certain shape, size and performance of metal parts blank forming methodAfter comparison: metal forging can improve the microstructure and mechanical properties of casting forging method after.
The mechanical properties of the casting is lower than that of the mechanical properties of the steel with the same material. In addition, the forging processing can ensure the continuity of the metal fibrous tissue, fibrous tissue to forging and forging shape consistency, metal streamline integrity, can ensure the parts with good mechanical properties and long service life by precision forging, cold extrusion, warm extrusion forging etc. the production process, are casting incomparable
Hot deformation due to metal deformation and recrystallization, the coarse dendrite and columnar grains turned into grain is fine and uniform equiaxed recrystallization structure, so that the original steel ingot segregation, porosity, porosity, slag compaction and welding, the microstructure becomes more closely, to improve the plasticity and mechanical properties of metals.
