Centrifugal casting: is a casting method in which molten metal is poured into a rotating mold, and the mold is filled under the action of centrifugal force to solidify and shape.
advantage:
1. There is almost no metal consumption in the gating system and the riser system, which improves the production rate of the process;
2. The core can be omitted when producing hollow castings, so the metal filling ability can be greatly improved when producing long tubular castings;
3. Castings have high density, few defects such as pores and slag inclusions, and high mechanical properties;
4. It is convenient to manufacture barrel and sleeve composite metal castings.
shortcoming:
1. There are certain limitations when used in the production of special-shaped castings;
2. The diameter of the inner hole of the casting is not accurate, the surface of the inner hole is relatively rough, the quality is poor, and the machining allowance is large;
3. Castings are prone to segregation of specific gravity.
application:
Centrifugal casting was first used to produce cast pipes. At home and abroad, centrifugal casting was used in metallurgy, mining, transportation, irrigation and drainage machinery, aviation, national defense, automobile and other industries to produce steel, iron and non-ferrous carbon alloy castings. Among them, the production of castings such as centrifugal cast iron pipes, internal combustion engine cylinder liners and shaft sleeves is the most common
