The max jacks we used was 5-6 jacks to line 5-6 mtr of length (Max) with a kiln dia of 4.2 mtr .The main reason we did not extend further up was the safety aspect and to have a flawless lining ...
Note: For very large diameter kilns (Ø > 5.6m) ISO shapes are recommended also for basic bricks, due to the greater taper, which increases lining stability during kiln start-up VDZ linings have approx. 30% more brick joints which provides increased flexibility and thermal shock resistance to the rings. Basic bricks have cardboard attached to compensate for higher thermal expansion.
