Coke Reactive CRI Loaded Coke Oven
It refers to the percentage of coke weight loss after reacting with carbon dioxide at 1100±5°C for 2h at a lumpiness of 20±1mm, expressed by the symbol Cr%.
Strength CSR after reaction
After the reaction, the coke was tested by the type 1 drum. The weight percentage of coke larger than 10mm in the coke after reaction, with the symbol Sar%
6.1 Coke reactivity
The index of coke reactivity is expressed as the percentage of the coke weight lost to the total coke sample before the reaction. Coke reactive Cr%
Calculate according to (1) formula:
Cr(%)=(G-G1)/G ×100…………………………(1)
: G----weight of coke sample, g
Loaded coke oven
G1----Remaining coke weight after reaction, g
6.2 Strength after reaction
After the reaction, the strength index is greater than 10mm after the drum
The fraction is expressed as a percentage by weight of the remaining coke. The intensity Sar% after reaction is calculated according to formula (2):
Sar(%)=G2/G1×100----------------(2)
: G2-----The weight of the coke after the drum is larger than 10mm.
7.1 The test results of coke reactivity strength after reaction are taken as the arithmetic mean of parallel test results.
