Sand casting is a process that uses sand to form mold. The type of sand that is used for steel parts casting is different from the type of sand used for other types of castings.
The sand needs to be very clean and free of any foreign objects. It also needs to be a consistent size so that the molds will be accurate. Steel parts casting requires very fine grain sand that is able to withstand the high temperatures of the molten metal.
Different Types of Sand Casting Sands
There are several different types of sand that can be used for this purpose, including silica sands, bentonite sands, and zircon sands. Each type has its own set of benefits and drawbacks.
Silica sands are the most commonly used type of sand for steel parts casting. They are very clean and have a very fine grain size. This makes them ideal for creating accurate molds. Silica sands are also relatively cheap and easy to find.
However, silica sands can be brittle and can easily break down under the high temperatures of molten metal. They also have a low melting point, which can cause problems with some types of steel alloys.
Bentonite sands are made up of clay that has been treated with a deflocculant. This treatment makes the clay particles more uniform in size and allows them to bind together better. This creates stronger sand that is less likely to break down under the high temperatures of the molten metal.
Bentonite sands also have a high melting point, which makes them ideal for use with certain types of steel alloys. However, they can be difficult to work with and can be expensive.
Zircon sands are made up of zirconium silicate. They are very strong and have a very high melting point. This makes them ideal for use with all types of steel alloys. However, they can be expensive and difficult to find.
Which Type of SAND CASTING SAND Should You Use?
The type of sand that you should use for casting steel parts will depend on the specific needs of your project. Silica sands are the most commonly used type, but bentonite and zircon sands may be a better option for some applications. Talk to your foundry supplier to determine which type of sand is best for your needs.
