Early pottery influenced by casting a larger ring gear standard, casting mostly agricultural production, religion, life and other aspects of the tool or appliance models ring gear, art color darker. BCE 513 years, the Chinese cast out the world's oldest written records found in cast iron FITTING - Jin cast tripod (about 270 kg weight). Ring gear around the 8th century AD prices in Europe began producing iron castings. After the Industrial Revolution of the 18th century, cast into the new era of large industrial services. Usually node speed and temperature deformation body for solving variable. Consider forming process at a time when the velocity and temperature fields in the future solve deformable body, you can get the coordinates of each point reflects the displacement field and deformation of the deformable body by the time integration. Accordingly geometric equations to calculate the strain rate can be further deformed body. Strain: constitutive equations and then by the initial microstructure of the material, temperature, strain, strain rate to calculate the stress; ring gear forgings, forging Super League (certified), Xinzhou ring gear forging Luoyang Super League Limited.
