FOUNDRY COKE
Foundry Coke is a fuel source
Made from heating specific blends of high-quality premium bituminous coal to extremely high temperatures (around 2000⁰ F) without oxygen. This drives off impurities, leaving behind mostly pure carbon.
Key Properties
Hard and Dense: Strong enough to support the weight of materials in a cupola.
High Carbon Content: Acts as the primary fuel source for extreme heat.
Low in Sulfur: These impurities can weaken the final metal products.
How Foundry Coke is Used
Foundries are the heart of its use, specifically using a furnace type called a cupola:
Melting Metal
Foundry coke’s ability to burn hot and consistently is key for melting metal like iron and scrap steel.
Fuel and Carbon Source
It provides both the heat needed for melting AND infuses the molten metal with additional carbon, influencing its final properties.
Structural Support
The coke’s structure creates a bed within the cupola, supporting the metal and other materials as they melt.
Products Made Using Foundry Coke
The majority of products made with foundry coke fall into the realm of cast iron:
Rail Transport
Engine components, suspension components, axle components, and brake assembly components.
Municipalities
Hydrants, valves, ductile iron pipe, manhole covers, manhole frames, inlet grates, storm water management, tree grates, park benches, and trench grates.
Automotive Components
Engine components, suspension components, driveline casings, and brake components.
Fitness
Free weights, kettlebells, and bike components.
Agriculture & Construction
Diesel engine and fluid power; ag implement and irrigation; tractors, loaders, and harvesting; and construction equipment components.
Industrial Equipment & Other Uses
Electric motor components; hydraulic components; HVAC components; hydrants, valves, and more; material handling components; and cookware
While cast iron is the primary focus, here are some other applications:
Rock Wool Insulation: A type of mineral fiber insulation
Sugar Refining: Used in purification processes
Smelting: Gold, silver and lead
