从China供应商批发进口9-15cm Foundry Coke Hard Coke For Iron Making — FOB条款

Foundry coke is a dense, low-ash carbon material produced by high-temperature carbonisation of bituminous coal in slot-type coke ovens, specifically sized 9-15cm lumps for iron foundry cupola furnaces. This Speed-branded hard coke from Xi'an Sibide Petrochemical Co., Ltd. carries a calorific value of 7000 J, fixed carbon at 88%, and sulphur at 0.6%. The abrasive resistance index of 7 and crushing strength of 90 indicate structural integrity during mechanical handling and furnace charging. These figures place it within the typical range for Chinese export-grade foundry coke used in small to medium blast furnaces and cupolas.

The ash content of 10% is standard for this grade, though premium foundry coke typically targets below 8% ash for cleaner iron production. Moisture at 7% requires controlled storage to prevent thermal shock during furnace injection. Phosphorus at 0.03% is favourable for ductile iron casting, as phosphorus above 0.05% can cause embrittlement. Volatile matter at 1.5% confirms adequate coking time and proper devolatilisation. The lump shape ensures uniform gas permeability in the furnace burden, a critical factor for consistent melt temperatures and metal quality.

Iron foundries, steel mini-mills, and metallurgical traders are the primary buyers of this material. The 9-15cm sizing suits manual charging systems and smaller cupola where uniform bed porosity matters more than high-speed automated feed. Buyers should confirm the supplier's actual production capacity, current export licence status, and whether the stated specifications represent a guaranteed certificate of analysis or typical production averages. Shaanxi Province has coke-producing clusters, though most export-grade foundry coke ships from Tianjin or Qingdao ports rather than Xi'an inland.

Xi'an Sibide Petrochemical Co., Ltd. is located at Room 1207, Jianke Building, No. 99 Yanta Road, Beilin District, Xi'an, Shaanxi Province, China. The company's registered address places it in Xi'an's central business district rather than a production zone, suggesting it operates as a trading company or commercial agent rather than a direct manufacturer. Its trust tier is marked as 'harbor', and its response rate is 0.00% with zero recorded average response hours, which indicates either a new listing, a dormant account, or that response data has not yet accumulated.

The product brand 'Speed' and model 'Speed hard Coke' appear to be the supplier's own naming rather than an internationally recognised coke brand. No manufacturing facility details, production capacity, export history, or additional verification documents are present in the available profile. Buyers should conduct direct due diligence on the company's actual role in the supply chain, whether it holds inventory or sources on order, and its experience with export documentation such as CIQ (China Inspection and Quarantine) certificates for coke exports.
