Steel-Grade CSR60 Foundry Coke, 85% Fixed Carbon — Product Guide & Benefits

Stable Quality and Measurable Performance

Every batch of L .T Graphite’s CSR60 Foundry Coke (Fixed Carbon 85%) is manufactured under strict process control to ensure consistent chemical composition and mechanical stability. Each product lot is carefully monitored from raw coal selection to post-carbonization screening, ensuring steady CSR values and uniform reactivity. This consistency guarantees that customers experience stable furnace conditions, predictable carbon yield, and reliable metallurgical performance. Through continuous optimization of our thermal processing parameters, L .T Graphite maintains a perfect balance between strength, porosity, and carbon recovery efficiency—key factors for achieving superior performance in steelmaking applications.

Precise Chemical Composition and High Fixed Carbon

Our foundry coke is engineered to deliver Fixed Carbon ≥ 85%, providing optimal energy content and high carbon transfer efficiency during steel production. The precisely controlled Ash ≤ 12% and Sulfur ≤ 0.6% levels minimize impurities in molten steel, ensuring a cleaner output and extended furnace life. Each composition parameter is verified using advanced analytical instruments, including carbon/sulfur analyzers and ash fusion testers. This meticulous approach ensures that our customers receive a product with predictable combustion characteristics and stable heat generation capacity, ideal for both blast furnace and foundry cupola operations where purity and efficiency are critical.

Customizable Size Range and Processing Adaptability

Recognizing the diverse requirements of global steel producers, L .T Graphite provides customized size distributions, typically ranging from 80–120mm, with additional options based on furnace specifications and charge systems. Uniform size distribution minimizes fines generation, ensures even gas flow, and stabilizes reduction reactions inside the furnace. Our advanced screening systems guarantee consistent particle size control and density uniformity. Whether your operation demands large, high-density coke for blast furnaces or smaller granules for foundry applications, L .T Graphite can adjust production parameters to deliver the perfect match for your process and efficiency goals.

Mechanical Strength and Coke Reactivity Index (CSR/CRI)

Mechanical strength is a decisive factor in foundry coke performance, as it determines the product’s ability to withstand high thermal and chemical stress within furnaces. L .T Graphite’s CSR60 Foundry Coke achieves Coke Strength after Reaction (CSR) ≥ 60 and maintains an optimized Coke Reactivity Index (CRI) for balanced performance. High CSR means the coke retains its shape and porosity even after exposure to CO₂ during the smelting process, ensuring consistent airflow and gas permeability. The combination of low CRI and high CSR results in efficient furnace operations, lower coke consumption, and improved carbon utilization—key metrics for steelmakers seeking cost-effective performance.
