Sand Casting Advantages of KOBELCO CK2500 Track Shoes
Recently, our factory is producing Kobelco CK2500 track shoes ordered by Canadian customers.
KobelcoCK2500 track shoes are produced by sand casting in our factory. We choose high-quality molding sand and core sand, which have the following properties:
1. Breathable type
After the high-temperature molten metal is poured into the mold, the mold is filled with a large amount of gas, which must be discharged smoothly from the mold. The property of the molding sand that allows gas to pass through is called gas permeability. Otherwise, defects such as pores and insufficient pouring will occur in the casting. The air permeability of the mold is affected by factors such as the particle size of the sand, the clay content, the moisture content and the compactness of the sand mold. The finer the sand particle size, the higher the clay and moisture content, the higher the compactness of the sand mold, and the poorer the air permeability
2. Strength
The ability of molding sand to resist external damage is called strength. Molding sand must have high enough strength so that it will not cause collapse during molding, handling, and box closing, and will not damage the surface of the mold during pouring. The strength of the molding sand should not be too high, otherwise the casting will be defective due to the decrease of air permeability and yield.
3. Fire resistance
After the high-temperature metal liquid is poured, it will have a strong thermal effect on the mold, so the molding sand must have the ability to resist high-temperature thermal action, that is, refractory. If the refractoriness of the molding material is poor, the casting is prone to sticky sand. The more SiO2 content in the molding sand, the larger the sand particles and the better the refractoriness.
4. Plasticity
Refers to the ability of molding sand to deform under the action of external force and maintain the existing shape completely after the external force is removed. The plasticity of the molding material is good, the molding operation is convenient, and the sand mold made is accurate in shape and clear in outline.
5. Concession
When the casting is condensed, the volume shrinks, and the molding sand should have a certain ability to be compressed, which is called yield. The yield of the molding sand is not good, and the casting is prone to internal stress or cracking. The tighter the molding sand, the worse the concession. Adding sawdust and other things to the molding sand can improve the yield.
