简介：Rotary kiln incineration is a desirable disposal option for steel-rolling oily sludge. However, ringing remains a key challenge in the highly efficient operation of rotary kilns. This study investigates the erosion behaviour of refractory bricks in a rotary kiln during steel-rolling oily sludge incineration and its effects on ringing. The degree of refractory brick erosion (i.e. iron permeation-depth and quantity) depends on the roasting temperature and time. In the same zones of the refractory bricks, iron permeation increases with the roasting temperature and time. This is because the molten substances generated from the steel-rolling oily sludge erode the refractory bricks, whereas the loosened surface of the eroded refractory bricks is conducive to the continual permeation of molten substances in the refractory bricks. These findings provide a useful reference for developing ringing mitigation methods for rotary kilns.
