Casting

The process by which metals and their alloys are melted and then molded into special molds is called casting. The materials used in casting are usually metals or mixtures such as cement, plastic or epoxy. The casting method is often used to make complex parts that are difficult or costly to produce through other methods.

Silica sand

One of the best and most important components of sand filtration is called silica sand, which is extracted from silica mines. This substance has the chemical formula of SIO2 and is one of the minerals that has many applications in many cases, including the water industry.

What is cast silica sand

Processed silica, which is used as a mold in various foundry industries, is called casting silica sand. Cast silica sand is first extracted from silica mines under the name of silica minerals and after various steps have been done on it, it becomes cast silica sand.

Casting silica sand after extraction in the factory is first processed and then crushed and washed and then, this material is dried and they are granulated in 8 different sizes according to the place of consumption.

Characteristics of casting silica sand

1. It has high purity silica

2. It has different granulations

3. Resistant to moisture

4. Compatible with a variety of operating conditions

5. Has resistance to temperature and heat

6. Its boiling point is high

Applications of cast silica sand

1. Use in casting molds for various metals such as iron, steel, copper, aluminum, etc.

2. Can be used as refractory in making ceramics, glass, cement production furnaces.

3. These sands can be used as more molding.

  4. Use in water purification.

5. Making cement.

6. Sand blast.

Advantages of casting silica sand

1. Since these sands have granulation, so finer grains of sand cause a significant increase and increase the strength of the molds.

2. For most sand castings, silica sand is used, which is abundant in nature and its access is easier and cheaper than other sands.

3. Molds made of sand can be dried in the oven shortly before pouring the molten material. Sand molds are stronger than wet molds and have a lot of precision dimensions.

4. Casting silica sand has a very high resistance at 2000 ° C. Fine-grained sands increase and increase the strength of these sand molds.

 5. Silica itself has a high boiling point and its expansion range is low, so cast silica sand has the same property, and according to this feature, cast silica sand can be used in the production of stable core and mold compatible with all temperatures.

Price of casting silica sand

The price of cast silica sand depends on only one factor, and that is the granulation of the sand. The finer the granulation of the cast silica sand, the higher the price.
