Operation Method and Notice for High Alumina Brick:

In order to make the material of kiln liner function fully and ensure its turnaround, prolong service life, making following provisions for the masonry:

1) Sweep carefully the dust and crumbs on the inside wall of kiln shell.

2) Inside wall of kiln shell should be level up and no irregularity phenomenon.

3) The mortar joint between bricks is controlled in 1.5mm~2mm.

4) Mortar smear should be uniformity and full. Don’t have the lack of the mortar phenomenon. You should smear well the mortar. And you twist mortar with brickwork to extrude a litter mortar.

5) Masonry of kiln liner must be level up and with no slab staggering .You should do your best to avoid malposition, lean, mortar joint uniformity, decentring, hemstitch, straight joint, yawn, bursted, raw seam, warp form the shape of the snake, humping and the mortar is unwell, etc are common faults.

6) According to design, the expansion gap of firebrick must remain. You cannot omit.

7) Firm whipstitch. You must process finely brick with brick cutter. Don’t process brick with hand. Neck brick should be larger 70% than other brick. The last brick in one plane or the brick in a curve should be 50% larger than other bricks. Fore shaft is the same brick. The machined surface is not suitable to facing the inside hearth.

8) Refractory should be stored in dry warehouse.

The bricks are packed on wooden pallet with papers in each layer and PP film wrapped outside of the whole pallet.
