How should repair the refractory lining of the iron runner
The iron runner lining does not receive all the erosion evenly during  use. In the later stage of use, partial damage, flaking, cracking may  occur, especially in the main iron runner. In order to balance the loss  of the lining of the refractory material , it is necessary to increase the service life while effectively utilizing it. A better way is to use the hot spray method.    For the iron storage trench, the residual iron stored at the bottom  of the iron runner must be cleaned out before the spraying operation.  Therefore, it is necessary to pay attention to selecting the appropriate  timing for spraying to achieve better results. The most suitable timing  for spraying should be selected when the iron line is damaged, and the  slag line concave and reaches a certain level. The timing of the  spraying should be selected when the surface temperature of the iron  runner lining is from 800℃ (reddish red) to 500℃ - 600℃ (beginning to  turn black).
