The difference between the forging pipe and the casting pipe? Generally speaking, the mechanical property of the casting is lower than that of the same material. In addition, 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, forging temperature and extrusion process production, casting is incomparable.
Forging is a piece made by forging, which is forged by impact force.
The microstructure and mechanical properties of the metal can be improved after forging. Metal fibrous tissue after forging method of hot deformation due to metal deformation and recrystallization, the coarse dendrite and columnar grains turned into finer grain size, uniform equiaxed grain, so that the original ingot segregation, porosity, porosity, slag compaction and welding, the microstructure became more closely, improve the plasticity and mechanical properties of metals.
Casting is a casting method to make parts. Casting is a mold or model, poured into the molten steel, cast out of the pieces.
The process of melting the metal into a liquid that meets certain requirements and pouring into the mold, after cooling solidification and cleaning, has a predetermined shape, size and performance.
Use of metal billets forging machinery pressure, the processing method of plastic deformation in order to obtain a certain mechanical properties, shape and size of forging.
