Raw Material For Wheel Forging Factory

The basic principles for determining the forging temperature range: ensure that the metal has better plasticity and lower deformation resistance in the forging temperature range. Guaranteed to obtain good quality (referring to internal organization and mechanical properties) wheel forgings. Expand the forging temperature range as much as possible in order to reduce the number of fires, save energy, and improve forging productivity.

When considering the above principles, we must establish the idea of quality first, and first ensure that the billet is heated well to ensure forging of high-quality wheel forgings and good plasticity. At the same time, we must reduce the number of heating fires, improve labor productivity and reduce heat energy loss.

In order to achieve high quality, high yield and low consumption, the relationship between furnace temperature or material temperature over time is specified in each stage of metal heating. This is the heating specification. The billet temperature refers to the temperature of the furnace from the beginning of the furnace to the completion of heating. And provisions for billet temperature change over time. For the convenience of application, the heating specification is expressed by the temperature-time change curve, which is usually expressed by the furnace temperature-time change curve (also known as the heating curve).

The basic principles for formulating metal heating specifications are high quality, high efficiency, and low consumption. It is required that the billet during forging does not generate heating defects (cracking, overheating and overburning, less oxidation and decarburization) during heating, uniform temperature, short heating time, High production efficiency and fuel saving.
