Gilsonite as foundry coke

Gilsonite as foundry coke using in steel foundries are facilities that produce steel castings. One of the uses of Gilsonite in foundry is that it is used as a carbon additive in steel castings because it has a high carbon content and is easy to work with. Carbon is added to steel to improve strength and durability, and Gilsonite is an excellent source of it. When Gilsonite is added to molten steel, it increases the carbon content, which improves the properties of the steel.

Gilsonite as foundry coke in Brass and Bronze Castings

Another facility that uses Gilsonite in their production process is brass and bronze castings. Like steel castings, Gilsonite is used as a carbon additive. Brass and bronze require carbon to improve their properties, and Gilsonite is the carbon source that these castings need to function properly.

Gilsonite in Iron Casting

Gilsonite is used in iron casting as a mold release agent. When molten iron is poured into a mold, it can stick to the mold surface, making it difficult to remove the mold. Uintite is used as a mold release agent because it has outstanding lubricating properties. It forms a thin film on the mold surface and prevents the molten iron from sticking to it.

Aluminum Casting

The uses of Gilsonite in casting are countless. Aluminum casting is another application that benefits from the valuable Gilsonite. It is used as a fluxing agent in aluminum casting. Fluxes are added to the molten metal to remove impurities and improve the quality of the casting. Gilsonite is an excellent lubricating agent because it has a high carbon content and is rich in minerals that can react with impurities in the molten metal.

Benefits of Gilsonite as Foundry coke using

Gilsonite is a natural gum rock with a high carbon and bitumen content. In foundry applications, it is commonly used as a molding additive and core sand due to its unique physical and chemical properties. Some of the benefits of using Gilsonite in foundry include:

Improved Flowability

Gilsonite improves the flowability of sand, making it easier to mold and shape.

Increased Strength

Unitite strengthens the mold by increasing the cohesion and reducing the porosity of the sand.

Reducing Defects

One of the uses of Gilsonite as foundry coke in casting is that it reduces the number of mold defects by creating better adhesion and preventing sand from sticking to the mold.

Increased Refractory

Gilsonite has a high melting point, which increases the non-burning of the mold sand and core. This property helps the mold to survive at higher temperatures without degradation.

Increased Durability

The use of Gilsonite as foundry coke in casting can improve the durability and strength of cores and sand molds. This can lead to fewer defects and longer mold life.

Improved release properties

Gilsonite acts as a release agent, making it easier to remove the mold from the pattern. This reduces the chance of mold damage and improves casting quality.

Reduces Cracking

Cracking is a common defect in casting that occurs when molten metal enters the mold sand. Gilsonite prevents metal penetration by forming a protective layer between the mold and the metal, reducing this problem. For this reason, the use of Gilsonite in casting is very important.

Reduced Production Time

Gilsonite  as foundry coke speeds up the molding process by reducing the baking time required for the mold. Overall, the use of uintite in sand molds makes the casting process more efficient and produces higher quality castings.

Reduced smoke and gas emissions

When cores and sand molds are exposed to high temperatures in foundries, gases are released that can cause defects in the cast parts. As a natural product, Gilsonite produces less smoke and gas during the casting process compared to synthetic resins.
