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.

Application of Binder in Stamp Charge Coke Making

weight of the coal charge to be taken for the test was calcu-lated so as to maintain a bulk density of 1150kg/m3. The card board box was positioned inside a steel mould and coal mass was transferred in parts into the card board box gradually and stamped manually with a rammer. The final coal cake thus made was charged into the Carbolite test oven.
