There are many things about crankshaft machining, so how much do you know? How much do you know about the casting technology of crankshaft machining? Today, let's discuss the casting technology of crankshaft machining with the Xiaobian new universe.

Smelting
The acquisition of high-temperature, low-sulfur, pure molten iron is the key to producing high-quality ductile iron. The domestic production equipment is mainly based on cupola, and the molten iron is not pre-desulfurized; the second is high-purity pig iron and poor coke quality. The molten iron is melted by a cupola, desulfurized outside the furnace, and then heated in an induction furnace to adjust the composition. The detection of domestic molten iron components has been generally carried out using a vacuum direct reading spectrometer.
modeling
The airflow impact molding process is obviously superior to the clay sand type process, and high-precision crankshaft castings can be obtained. The sand mold produced by the process has the characteristics of no rebound deformation, which is especially important for the multi-turn crankshaft. Some crankshaft manufacturers in China have introduced airflow impact molding processes from Germany, Italy, Spain and other countries. However, only a few manufacturers have introduced the entire production line.
Electroslag casting
Electroslag remelting technology is applied to the production of crankshafts, which makes the performance of cast crankshafts comparable to forging performance. It has the characteristics of fast development cycle, high metal utilization rate, simple equipment and superior product performance.
