Abstract:

Due to the irreversibility of silica brick temperature drop during secondary heating-up for coke oven battery,thus there would be a certain difference from the newly\|built battery in thermal expansion.i.e.the battery will have an obvious total expansion after the secondary heating-up,but a relatively smaller expansion during the heating\|up.Furthermore the expansion rate goes down before 300 ℃ during the heating-up and goes up after 300 ℃.
