Brake disc has been widely used in the braking system of rail vehicles. Vermicular graphite cast iron is a new
1. Melting process of alloy vermicular graphite cast iron for brake disc (1) Raw materials and chemical composition Pig iron,
Taking a brake caliper casting of MQB platform of Volkswagen as the research object, a series of research on the
According to the above theory, in order to meet the requirements of the sectional area of the sprue, it is
(1) The 3D scanning equipment is used to scan the casting surface one by one, and then the three-dimensional surface
The proportion of raw materials for smelting is scrap: recycled material = 4:6, and the composition of molten iron after
(1) Confirmation of number of cavities and type of gating system The equipment model is disa230x, and the mold plate
The gating system is composed of a gate cup, a runner, a sprue and an inner gate. It is a
To obtain a dense casting, the sprue cup should be poured as soon as possible and always filled during the
The flow rate W is defined as the metal weight passing through the cross-sectional area of the gating system within
Before designing the mold process, the natural properties of the parts should be analyzed, including weight, volume, surface area, number
The calculation of flow velocity at specific position of gating system is based on Torricelli formula of ideal free falling
With the application of ductile iron in the global industrial field more and more widely, the quality requirements of ductile
Based on the previous calculation methods and results, some calculation factors have been modified by zhougengao Engineering Co., Ltd., and
Because of the special solidification property of ductile iron, it is easy to produce shrinkage cavity and shrinkage porosity. How
Automobile brake is the most important part of automobile chassis system, which bears the main responsibility of safe driving. In
