Gilsonite for Foundry Coke

Gilsonite for foundry coke is used as a binder for molds and sand cores. It improves the strength and durability of molds and also reduces the risk of burn-in defects during the casting process. Gilsonite can also be used as a coating for metal castings to improve their appearance and protect them from corrosion. In addition, it can be added to refractories to increase their thermal conductivity and improve their resistance to high temperatures. The general applications of Gilsonite in foundry are listed and explained below:

Gilsonite acts like glue

Sand glues are materials that are combined with sand to create a mold into which metal is cast. Gilsonite is an excellent choice as a sand glue for several reasons. First, it has a high softening point, which means it can withstand high temperatures without melting or breaking down. This property ensures that the mold can withstand heat during the casting process without losing its shape. Second, Gilsonite has high adhesion, which means it can bind sand particles together, creating a strong and durable mold. It can also reduce the amount of resin needed, which saves costs.

Gilsonite for foundry coke in Core Making Process

Core making is used to create cavities or spaces in castings. Gilsonite for foundry coke is also used in the core making process in foundries. The use of Gilsonite in casting and core making processes ensures that a high quality sand mixture is created that is able to withstand the heat of the casting process. In addition, the use of Gilsonite in core making ensures that the sand mixture hardens uniformly, resulting in better core strength and greater accuracy.

Carbon Additive

Most importantly, Gilsonite for foundry coke is used as a carbon additive in foundries. Gilsonite’s carbon content makes it an ideal choice for addition to steel and iron alloys. The carbon additive increases the hardness and strength of the alloy and prevents it from cracking during the casting process. The carbon additive also helps reduce the shrinkage of the alloy, which results in a smoother and better surface finish in the final product.

Molding Process

Gilsonite for foundry coke can be used in molding sand to improve properties such as strength, durability, and resistance to heat and moisture.

Coatings

Gilsonite can also be used to create coatings that protect molds and casting cores from damage caused by wear or corrosion.

Casting Release Agent

Another application of Gilsonite in casting is that it can be used as a casting release agent, which prevents castings from sticking to the mold or core.

Temperature resistance

Gilsonite can withstand high temperatures and can be used to produce molds and casting cores that are capable of withstanding extreme temperatures.
