(2) outside at body of heater, manual demolition gas permeable brick locking latches, adopts gas permeable brick draw-off gear that gas permeable brick brick core is slowly extracted;
(3) foreign material around cleaning gas permeable brick brick core, at new gas permeable brick brick core outer surface and old gas permeable brick cover brick and brick core contact surface, evenly smear refractory mortar, then new gas permeable brick brick core is installed, masonry is compressed, install gas permeable brick locking latches, anode furnace is gone to normal operation position, and hot replacing gas permeable brick operation completes immediately.
Further, in step (2), when new gas permeable brick brick core is installed, gas permeable brick brick core is preheated to 70～100 ℃, and then installs.The object of preheating is that the physics moisture of gas permeable brick brick core is dried, after preventing that gas permeable brick brick core from installing, in production and application process due to too fast the bursting of heating up.
Further, as scaling loss also appears in gas permeable brick cover brick,, in step (2), manual demolition gas permeable brick overlaps brick simultaneously; In step (3), at new gas permeable brick brick core and cover brick outside surface and old gas permeable brick brick seat, evenly smear refractory mortar with cover brick contact surface, then new gas permeable brick brick core and cover brick are installed, masonry is compressed, install gas permeable brick locking latches, anode furnace is gone to normal operation position, and hot replacing gas permeable brick operation completes immediately.
In Rotary Anode Furnace is produced, gas permeable brick brick core is the part of easy scaling loss, after gas permeable brick cover brick works long hours, also may occur scaling loss, gas permeable brick miscellaneous part generally there will not be damage, so conventionally only need replacing gas permeable brick brick core and cover brick just can guarantee the normal operation of gas permeable brick system.
Beneficial effect of the present invention is: working method is simple, and the replacing time is short, little to rotary kiln Influence of production, has reduced production cost; Guarantee workman's operational safety, avoided operation under hot environment.
