Effects of Stamped Charging on the Strength of Coke

2013-12-24  The stamped density for the Agro-Allied coal is lower than the 1,200kg/m 3 for stamped charge carbonization in the German Zentralkokerei Saar plant [8] but similar to 800 to 1,000kg/m 3 used for preheating/stamped charging in China [5]. It is also within the range of 800 to 1,160 kg/ m 3 for stamped charge coal in India.

Stamped coal cakes in cokemaking technology: Part 2

Abstract Coking of coal blends using high volatile coals with poor caking properties to produce a high quality coke for blast furnace application can be achieved by compacting the whole coal blend before the pyrolysis in the so called stamp charge operation. Using stamp charging not only improves the flexibility of the cokemaking plant using cost efficient raw materials, but also increases

Stamp charging technology Rudolf Lesch Consulting

During the stamp charging process, the coal is stamped outside the coke oven, into a single „briquette“ (coal cake), having almost the same dimensions as the oven chamber. This coal cake reaches a density of up to 1.15 t/m³ (on wet coal basis with 10% water) about 30% more than with the loose coal-charge during conventional top

Using stamp charging not only improves the flexibility of the cokemaking plant using cost efficient raw materials, but also increases oven throughput. Therefore, in recent years, densification of coals has been introduced even to coals with good

Stamped and pressed coal cakes for carbonisation in

Coal is compacted by stamping, if the so-called stamp charging process applied. Compacting of the coal by pressing is used in case of the cokemaking with so called heat-recovery ovens. Stamped and pressed coal cakes require over the cake volume uniform high density and mechanical stability.

Corporación Aceros Arequipa is the largest Peruvian steelmaker. The company operates a facility in Pisco, 241 km South from Lima, on the Pacific Ocean, a facility including a meltshop with a capacity of 850.000 tpa of liquid steel, and rolling mills

PILOT PLANT EXPERIENCE USING STAMPED

Six domestic coal were selected, plus anthracite. As imported coals, three Colombian and four American coals were selected. Taking into account the poor coking properties of domestic coals, stamped charging was adopted. A maximum participation of 80% domestic coal was obtained in blends with 20% of a Columbian coal.

The stamped charging of coals, developed in Europe and adopted in China and India, allows the use of high volatile poor coking coals, soft and semi soft coals as well as inerts like petroleum coke and anthracite without impairing coke quality.

Automatic Stamping Charger—Stamping of Blended

The coke plant of a steel plant corresponds to the area that transforms a blend of coal into coke for using in blast furnace and steam to power plant. The coking plant of ThyssenKrupp CSA uses the heat recovery technology with stamping charger for stamping and preparation a blend of coals for charging and coking.

Instead of the conventional top charging method, stamped charging involves feeding already compacted coal briquettes into the oven horizontally. This ensures a better quality of coke and a reduction in the share of expensive grades of coal, as stamped coke particles bake better, boosting the CSR and increasing resistance to mechanical stress during transportation and loading into the blast
