Different installation methods for cast iron platforms

The cast iron platform has good casting performance. It has a low melting point and good fluidity. Also, due to the breaking of stone nitrogen, it shrank in size. In addition, the low cost of the bottle does not require high fire resistance for the type silicon and core sand. Make it a widely used casting alloy.

Among various common cast iron platforms, gray cast iron platforms have good casting performance. It has good fluidity and can pour small, thin-walled castings with complex shapes. At the same time, due to its small shrinkage, except for large castings, it rarely sets up risers and only has exhaust ports.

And generally, wet casting can be used, so when using gray cast iron platform casting, the equipment is simple to operate, the production string is high, and the cost is low. Due to the need for spheroidization before pouring, the ductile iron platform may experience a decrease in the temperature of the molten iron and lower settling properties. The shrinkage of the ductile iron platform is also larger than that of the gray cast iron platform.

In the small machining process, first position the cast iron platform on the machine, then use fixtures to fix it, and then use cutting tools to machine the parts of the casting that need to be processed. After the machining is completed, loosen the fixtures.

The cast iron platform is adjusted to a horizontal position, with the load evenly distributed on each support point. The ambient temperature is (20 ± 5) ℃, and vibration should be avoided during use. The cast iron platform has the advantage of being installed with shims and KUAIJIE, making it easy to move.

Installation method of cast iron platform:

1. Bracket installation: Gently place the cast iron platform onto the bracket and adjust the fine adjustment bolts on the bracket to the level of the cast iron platform. The bracket can reduce the labor intensity of inspectors. The height of the bracket is generally around 500-600mm

2. Installation of shim: Adjust the cast iron platform to a horizontal position and evenly distribute the load on each support point. The ambient temperature is (20 ± 5) ℃. Avoid vibration during use. The advantage of using shims for installation on cast iron platforms is that they are easy to install and move.

3. Installation of foundation bolts: The cast iron platform designs the installation method according to the user's requirements, and the foundation bolts are installed.

4. Anchor installation: Cast iron platforms can be designed for anchor installation. First, the user prepares the foundation and embedded holes according to the drawings of the cast iron platform, and then places the anchor in the reserved holes set in advance to adjust the level of the cast iron platform.

The working surface of the cast iron platform should not have defects such as cracks, scratches, bumps, rust, or loose material. User acceptance criteria for cast iron platforms: The surface quality of the cast iron platform and the working surface of the cast iron flat plate should not have defects such as cracks, scratches, bumps, rust, and loose material. The working face of the cast iron flat plate (cast iron platform) for subsequent inspection is allowed to have the above-mentioned defects that do not affect its performance. The cast iron flat plate (cast iron platform) to be inspected first should be molded with sand and flat, without sharp edges or burrs, and painted firmly.

On the working face of the cast iron platform, sand holes with a diameter less than 15mm are allowed to be blocked with the same material, and their hardness should be lower than that of the surrounding materials. The number of sand holes blocked in the working face should not exceed 4, and the distance between sand holes should not be less than 80mm. The cast iron platform (cast iron platform) should be non-magnetic. The cast iron platform should have three main support points, which should be located in accordance with the principle of small deformation, generally at 2/9 of the side length of the flat plate. Auxiliary support points should be added to cast iron plates with dimensions greater than 1000mm × 1000mm.
