China Manufacturer High Carbon Foundry Coke with 85%-90% Low Sulphur Low Ash for Calcium Carbide Melting

Foundry coke, famously known as hard coal coke, is meticulously crafted in non-recovery coke ovens. It plays an indispensable role in the melting of iron and a myriad of other metals like lead, copper, tin, and zinc within the robust environment of a cupola furnace at foundries. Distinguished by its denser structure, high carbon content, and low ash, its exceptional heating value and size surpass those of metallurgical coke, ensuring an optimal fit for the dimensions of the cupola furnace. It functions as a durable supporting matrix, an efficient reducing agent, and a powerful energy carrier during the intricate process of pig iron manufacturing. Embracing large-sized coke offers notable advantages such as reduced blasting pressure, heightened metal temperature, minimized breakage during handling, and decreased reactivity with CO2, making it a cornerstone in metallurgical processes.

The global foundry coke market is comprehensively segmented based on furnace size, process, metal smelting type, and geographical region. Specifically, in terms of furnace size, the market is categorized into 600-1200 mm, 1200-1800 mm, and those above 1800 mm. Primarily, foundry coke serves as the powerhouse of the cupola furnace, with its size precisely tailored to the internal diameter of the furnace. As furnace size escalates, the size of foundry coke required also increases, ensuring optimal performance and efficiency.

Celebrated for its essential application in blast furnaces, foundry coke is indispensable for the smelting of non-ferrous metals like copper, lead, zinc, titanium, and antimony. It not only provides the critical heat required but also impeccably stabilizes the carbon content of the resultant metal product. The production process of foundry coke demands lower temperatures and extended durations compared to that of blast furnace coke. Boasting a large block size, low reactivity, minimal porosity, along with outstanding shatter strength, and low ash and sulfur content, foundry coke remains a pillar of the industry.
