nodular cast iron

Firstly, from the aspect of changing the height of nodular cast iron pouring riser, without changing the diameter and neck

According to the simulation results in the previous section, it is found that the feeding channel of riser neck is

The temperature distribution of nodular cast iron during solidification of automobile hub support is shown in Figure 1. As can

Nodular cast iron belongs to a typical paste solidification mode. The possibility of shrinkage porosity, shrinkage cavity, air hole, slag

(1) Material definition The material used in the simulated automobile hub support is the high strength and Toughness Nodular Cast

Using ugnx12 0 software to model the pouring and feeding system of automobile hub support. UG NX12. 0 is a

After the molten metal is poured into the mold, it usually produces volume shrinkage in the process of solidification and

After determining the type and layout of the nodular cast iron gating system, it is necessary to calculate the specific

The function of sand core is to shape the hole, inner cavity or parts that are not easy to produce

To design the process of nodular cast iron, in addition to selecting the correct casting method and process scheme, the

The selection of parting surface is directly related to the dimensional accuracy, production cost and efficiency of nodular cast iron.

According to the actual production situation, the automobile hub support casting is produced by using the Japanese Xindong automatic pouring

Spheroidizing treatment and inoculation treatment are essential pre furnace treatment steps for raw molten iron of nodular cast iron. The

In order to obtain as cast ferrite pearlite nodular cast iron with high strength and good plastic toughness, the production

The automobile hub support is an important support of the rear suspension system of the car, one for the left
