Partial Repair of Damaged Coke Chamber Walls
A research program was started in 1978 to find a better method for the repair of coke chamber walls.
The damage occuring after the rebuilding was thoroughly investigated as well as the repair method used. Displacement and temperature measurements were carried out during the reheating period. Large temperature gradients were found.
Bricks were tested for crack formation in a laboratory furnace, simulating the situations occuring during the repair. Critical heating rates, critical temperature gradients and maximum thermal shocks in different directions, with or without external stress, were appointed for the used silica-bricks.
