从China供应商批量进口30-80mm Low Ash 12.5% Metallurgical Coke

This 30-80mm low ash metallurgical coke from Shahe Ji Jin Petroleum Coke Trade Co., Ltd. is a blast-furnace grade coke with fixed carbon exceeding 86.5 percent and ash content of 12.5 percent. The size fraction 30-80 mm is the standard nut coke range used in ironmaking, providing the permeability and mechanical strength required for burden support and gas distribution in the shaft. The supplier states the product is suitable for steel and iron industries, foundries, and other high-temperature carbonisation processes where low ash and high fixed carbon are critical to metal quality and furnace productivity.

Metallurgical coke of this grade is produced by carbonising bituminous coal in slot-type or stamp-charge by-product coke ovens at temperatures above 1000°C. The 12.5 percent ash figure indicates mineral matter remaining after carbonisation; lower ash reduces slag volume and flux demand in the blast furnace. The 30-80 mm size class is typically produced by screening larger blast furnace coke or, in some operations, as primary graded product. Standard complementary tests for this material include M40 and M10 drum indices (mechanical strength), CSR (coke strength after reaction), CRI (coke reactivity index), and sulphur content, none of which are stated in the source data and must be requested from the supplier.

Primary buyers are integrated steel plants, independent pig iron producers, ferro-alloy smelters, and large foundries operating cupolas or arc furnaces. The material is shipped in bulk, typically via sea in geared or grab-equipped vessels, or in containers for smaller trial quantities. The supplier mentions wholesale and bulk supply without stating minimum order quantity, packaging options, or standard shipment size. Before purchasing, buyers should request a complete certificate of analysis, confirm whether the 12.5 percent ash is typical or guaranteed maximum, and establish sulphur, phosphorus, and moisture limits contractually.

Shahe Ji Jin Petroleum Coke Trade Co., Ltd. is located west of Jiankang Road, Shahe City, Xingtai, Hebei Province, China, postal code 054000. The company holds an imported supplier tier and a harbor trust tier on the platform. As with the first listing, the response rate is shown as 0.00 percent and average response hours as zero, indicating no response data is available. Buyers should not assume responsiveness and should initiate contact early to gauge communication reliability.

The supplier trades metallurgical coke and petroleum coke products for industrial applications. The listing does not provide year of establishment, registered capital, warehouse or port facilities, annual trading volume, number of employees, or export licence details. No factory ownership is claimed, suggesting the company may operate as a trader or distributor rather than a primary manufacturer. Buyers should request company registration documents, audited financials, and evidence of supply chain control before entering into contractual commitments.
