Casting industry is a common method used to make raw materials into useful pieces of materials we use in everyday life. Simply, in the casting process, liquid or molten material is filled with molds and cooled. The cavity of the mold is produced as we want it to take the shape of the material. The raw material is generally heated and melted in ovens and the cavity in the mold is formed by the model part. Some important types of casting are; Sand mold casting, full-die casting, centrifugal casting, pressure casting and precision casting.

Olivine sand casting is a method used in the casting of metals because it is very popular in the past and is very cheap nowadays. At the beginning of all operations, the model part is made with technical drawings. The model part can be composed of one or two parts and this number depends on how complex the part is. The model is placed into the mold and the remaining voids are filled with a sand blend. Thus, the pattern is obtained in the shape of the mold. The core of the sand mixture is placed in the cavity to form the cavity of the part. The upper half of the mold is placed on the lower half to obtain the mold of the part. The liquid metal is poured into the mold and allowed to cool in this mold. After cooling and hardening, the sand mold is broken and the piece is obtained.

Olivine in Casting Industry

Generally quartz sand is used as a casting mold in casting industry. Quartz sand, however, reacts with the metal during casting due to its low melting temperature, causing the steel to sinter on the sand. This problem is especially experienced in manganese steel castings.

Due to the high melting property of olivine mine, the casting mold does not react with the metal and does not damage the steel surfaces. In general, the casting mold and the inner part of it are in the form of flour (grain size 74-50 microns) olivine coating is used. This coating in the refractory property ensures that the casting can be easily separated from the mold. Another feature of this field that gives the olivine to the foreground with respect to the silica sand is the minimum defects that can be caused by expansion during casting because of the low expansion coefficient. In addition, due to this property consumption of binding components such as bentonite and water is also reduced.

In addition to these, resistance to heat, ease of shaping and being able to re-use well calcined because it has low water content is another outstanding feature of olivine gemstone against quartz sand. Another important feature of olivine is that it causes silicicosis, a deadly lung disease, while olivine does not cause such a problem because olivine has low free silica content.
