This 0-1mm calcined petroleum coke carburizer is manufactured through high-temperature calcination in a rotary kiln, followed by targeted crushing and classified screening. It features dense particle structure with controlled residual volatile matter and delivers stable carbon absorption under conventional smelting conditions. As a cost-effective metallurgical carbon material, it is suitable for medium-grade cast iron production and electric arc furnace steelmaking. It helps customers balance the service performance of castings and reasonably control raw material procurement costs in mass production.
Made from green petroleum coke via high-temperature calcination in a rotary kiln, this product has dense particles without undergoing graphitization. It exhibits moderate reactivity and acceptable oxidation resistance at conventional smelting temperatures. Its carbon dissolution rate is lower than that of graphitized carburizers, yet it boasts outstanding cost advantages. In addition to medium-grade gray cast iron casting, it is also used for carbon composition adjustment in electric arc furnace steelmaking and ferroalloy smelting. As an economical metallurgical carbon material, it stabilizes nominal carbon indicators. It is especially fit for large-scale continuous casting production and effectively reduces overall production costs.
This 0-1mm calcined petroleum coke carburizer adopts qualified green petroleum coke as raw material. It undergoes high-temperature rotary kiln calcination, crushing, classified screening and impurity removal to obtain granular products with uniform particle size distribution. The particles have a dense structure and moderate reactivity. Although its carbon dissolution speed is inferior to the graphitized series, this economical carbon material is applicable to mass medium-grade casting, EAF steelmaking and ferroalloy smelting while maintaining stable carbon indicators. Complying with ISO quality control standards, each batch is inspected for fixed carbon, volatile matter, sulfur and particle size distribution, providing cost-effective carbon raw material solutions for metallurgical and foundry enterprises.

FAQ
Q: What is the core performance gap between calcined petroleum coke carburizer and graphitized carburizer?
A: Calcined petroleum coke carburizer only undergoes calcination rather than ultra-high-temperature graphitization. It has poor crystal regularity, slower carbon dissolution rate and slightly lower carbon recovery rate. However, it presents obvious cost advantages for ordinary mass production.
Q: Why is strict control over residual volatile matter of the 0-1mm calcined carburizer required?
A: Excessive residual volatile matter will cause fierce bubbling and churning inside molten iron. Violent boiling of the melt increases splashing risks and brings potential safety hazards to on-site smelting operations.
Q: For mass continuous production of medium-grade gray cast iron, what feeding method helps improve the carbon recovery rate of calcined carburizer?
A: It is suitable to be added together with scrap steel at the initial charging stage, allowing particles sufficient residence time in the high-temperature molten bath to promote gradual dissolution of calcined coke particles.
Q: Is the 0 1mm calcined petroleum coke carburizer applicable to the production of high-strength nodular cast iron?
A: It is not the preferred option. Calcined coke carries the risk of high nitrogen content, which weakens graphite nodulizing effect. Low-nitrogen graphitized carburizer is recommended for high-end nodular iron.
Q: What problems will be triggered if the actual particle size is finer than the designed 0-1mm specification?
A: A higher proportion of fine powder leads to increased oxidative burnout when passing through furnace flame. It directly causes fluctuations in carbon recovery and raises difficulties for furnace operators to adjust carbon content of molten iron.
Q: What are the key points for warehousing of 0-1mm calcined petroleum coke carburizer packed in bulk tonne bags?
A: Keep the warehouse dry. Long-term moisture exposure causes particle agglomeration. Hard lumps are hard to disperse after being charged into the furnace and result in delayed carbon dissolution in molten iron.
