Chapter 1: Investment Casting Process The melting process in investment casting involves melting the chosen alloy, preparing the ceramic shell, and

Fixed disk investment castings have different filling states during the initial process plan filling process. The filling state diagram for

1. Determination of pouring speed The pouring speed was calculated using the Kalgin formula in the experiment: Where: v is

1. Selection of runner The overall structure of the fixed disk investment casting is irregular, with a through hole with

At present, automobiles are fully used in national life, and the stability of automotive components is receiving increasing attention. The

The gravity top-pouring casting process is selected. Due to the complex internal structure of the turbine guide casting, hot spots

As shown in the figure, the finished product of the investment casting of the turbine guide poured by this gating

As shown in the figure, the solid fraction and shrinkage porosity distribution of the gating system, where the shrinkage porosity

The premature solidification at the intersection of the inner runner and the investment casting of the turbine guide in the

The solidification process of the investment casting of the turbine guide is shown in Figure (a). The melt begins to

The investment casting material K438 of turbine guide is a nickel-base superalloy widely used in aerospace and has excellent high-temperature

The investment casting process is used to produce 100 rod-shaped titanium alloy castings in batches. The cast titanium alloy castings

The wax mold is made with medium-temperature wax, the gating system scheme is the optimized investment casting process scheme for

Through the simulation analysis of two investment casting process schemes, it is determined that the theoretical scheme of proportional solidification

Figure 1 shows the mold filling and solidification of the investment casting process plan. It can be seen from Figure

Figure 1 shows the mold filling and solidification of the investment casting process plan. From Figure 1, it can be

The density of titanium alloy is small, and the static head of feeding in the mold during vacuum casting is

Titanium alloy has low density, high strength and good corrosion resistance, and is widely used in aerospace, naval and other
