Coke strength after reaction
Coke Strength after Reaction (CSR) refers to
coking coal for export sale.[1]
Test procedure
In the test, a 200 g sample of 19–21 mm particle range coke is heated at 1100°C under 1
atmosphere pressure of carbon dioxide for 2 hours. The coke is preheated and cooled under nitrogen and the weight loss during reaction is measured. The percentage weight loss is known as the reactivity (CRI). The reacted coke is placed in an I-type drum (no lifters) and subjected to 600 revolutions in 30 minutes. The percent of carbon
material removed from the drum that is ≥10 mm is known as the coke strength after reaction (CSR).
