What is a crankshaft?
The crankshaft is the most important part of an engine.
1. It takes the force from the connecting rod and converts it into torque through the crankshaft output and drives the other accessories on the engine to work.
The crankshaft is affected by centrifugal force of rotating mass, periodic gas inertia force and reciprocating inertia force, which makes the crankshaft bear the action of bending and torsional load.
2. Therefore, the crankshaft is required to have sufficient strength and stiffness, and the journal surface should be wear-resistant, uniform and balanced.
Several casting techniques are used in the crankshaft production process:
1.Smelting
Obtaining high temperature and low sulfur pure hot metal is the key to producing high quality ductile iron. Domestic production equipment is mainly based on cupola, and hot metal is not pre-desulfurization treatment; This is followed by less high purity pig iron and poor coke quality. Molten iron is melted in cupola, desulfurized outside the furnace, and then heated and adjusted in induction furnace.
2.moulding
The air impact molding process is obviously superior to the clay sand molding process, and can obtain high-precision crankshaft castings. The sand mold produced by this process has the characteristics of no rebound deformation, which is especially important for the multi-throw crankshaft.
3.Electroslag casting
Electroslag remelting technology is applied to the production of crankshaft, so that the performance of cast crankshaft may be comparable to that of forged crankshaft. And has the characteristics of fast development cycle, high metal utilization rate, simple equipment, superior product performance and so on.
