Centrifugal Casting

Centrifugal casting, also known as rotocasting, is a casting method that is used to manufacture cylindrical components with complex designs and shapes. This casting process involves spinning the casting mold in a centrifuge at high speed and pouring liquid metal into the mold. Since the mold is spinning, centrifugal force is used to distribute the liquid metal evenly throughout the mold; this ensures that the part that is being produced is of homogenous quality.

Centrifugal casting is often used to produce aerospace parts, tools and components in various industries, such as the automotive, manufacturing and marine industries. This process has several advantages over other casting techniques such as improved physical properties, an even and uniform distribution of alloying elements and an excellent surface finish.

Centrifugal casting is often used for the production of components with complex shapes and intricate designs. This process makes it possible to produce parts with a good surface finish, as well as a good internal structure. Parts produced with this process provide higher strength and less porosity compared to parts produced via other casting processes.

The centrifugal casting process is a continuous process, which allows you to produce multiple parts at once. Typically, the casting is done in a horizontal position, with the mold spun on an axis at high speed. The molten metal is poured into the mold, and centrifugal forces force the molten metal outwards so that it coats the entire surface. The molten metal is then allowed to cool and solidify, forming the component.

In order to ensure the quality of the component being produced, the centrifugal casting process is usually accompanied by other treatments such as carbonitriding and tempering; these treatments help to improve the component’s mechanical properties, such as strength and toughness. The process can also be coupled with post-casting techniques such as shot peening and finishing in order to achieve a better surface finish.

Centrifugal casting is one of the oldest and most reliable casting techniques available today, and is often used for the production of components with complex shapes and intricate designs. This process can be used to produce parts with a high degree of accuracy and that are of homogenous quality. It is also cost effective and efficient, and can be used to produce high volumes of parts for a variety of industrial applications.

Metal CK15 (JIS) is a carbon-nitrogen treated steel, which is processed through carburizing and quenching followed by tempering and tempering. CK15 has a carbon content of 0.14-0.17%, nitrogen content of 0.17-0.36%, manganese content of 0.50-1.10%, and 0.90-1.20% chromium content. The hardness is ......

Metal CK15 (JIS) is a carbon-nitrogen treated steel, which is processed through carburizing and quenching followed by tempering and tempering. CK15 has a carbon content of 0.14-0.17%, nitrogen content of 0.17-0.36%, manganese content of 0.50-1.10%, and 0.90-1.20% chromium content. The hardness is mainly determined by heat treatment.

The microstructure of CK15 (JIS) steel is mainly martensitic structure. It has good strength, good machinability, wear resistance and corrosion resistance. In the metallographic analysis, the steel has coarse grains and large amounts of fibrous structures. The grains are mainly composed of martensite and retained austenite. In addition, there may be some ferrite and carbon-rich particles.

The mechanical properties of CK15 (JIS) steel are mainly controlled by heat treatment and control of the cooling rate. After carburizing, quenching and tempering, the sample can reach a high hardness and tensile strength of 1260 MPa and an elongation of 35%. The tempering temperature is related to the hardness and strength. When the tempering temperature is higher than 500℃, the hardness and strength of the material will be reduced, but the elongation and impact toughness will be improved.

In conclusion, CK15 (JIS) is a carbon-nitrogen treated steel, with good strength, machinability, wear resistance and corrosion resistance. Careful control of the heat treatment process is necessary to obtain the desired mechanical properties.
