Factors affecting the cold strength of coke
Thread Content
What factors are related to the cold strength of coke? The coal blending ratios for the two sets of coke ovens in Phase 1 and Phase 2 of our plant are exactly the same; then why is the wear resistance of the ovens in Phase 2 not as good as that of those in Phase 1?
It seems that cutbacks were made in the production of the second-phase equipment
The conditions of the furnaces are different. Our plant has two furnaces with a diameter of 4.3 meters, and they were put into operation half a year apart. To achieve the same temperature, Furnace No. 2 needs to have a pressure of 200 Pa higher than that of Furnace No. 1. The coke produced by these furnaces has not been analyzed separately, so it’s not known whether there are any differences between them.
This is normal; the key is to check whether the resistance is the same, as there can sometimes be differences in the readings shown by the instruments.
Check the coal cake density of the rammers in the two groups of coke ovens and you’ll know
