Roller kiln integral masonry steps and technical requirements

Masonry steps

(1) according to the building drawings on material type, size and area laying refractory insulation materials.
(2) to determine and calculate the side hole brick and kiln outside the frame transmission center position.
(3) side of masonry wall refractory insulation materials, and then laying at the bottom of the refractory insulation materials, again to kiln enclosed ceiling.
(4) generally from the kiln kiln head start laying, depending on how many distribution of masonry construction personnel, but should be done in conjunction with the cross construction process as far as possible.

Laying the technical requirements

(1) refractory mud soak time within 24 hours, and stir well.
(2) masonry mud plumpness: > 90%.
(3) according to the national standard 2 kinds of masonry building, the mortar joint: 2.0 mm or less.
(4) width expansion joint requirements: 5 mm; The length direction of the expansion joint requirements: 10 mm. All masonry wall layers that face brick dislocation. Thermal belt every 1 ~ 1.2 m for a dilatation joint, temperate in every 1.5 m stay together, every 2 m for a low temperature area. Bottom wall in the same cross section at the centre of the unified leaves 10 mm expansion joint, side wall layer displacement seam. All expansion joints according to each temperature zone with the corresponding specifications of the refractory fiber cotton.
(5) masonry construction in strict accordance with the drawings of refractory insulation material requirements specifications, variety, size.
(6) condole top brick, top side, roof insulation cotton, kiln top expansion joint and expansion joint of insulation fibre felt, masonry construction according to drawings on the spot.
(7) according to the casing outside the kiln kiln body all the size of holes corresponding masonry structure all the size of holes. Hole size including accident treatment bore holes, burner, observation, thermocouple hole, nasty cold wind pipe hole, etc.
The plug (8) refractory insulation cotton places must be full.
(9) inside the kiln wide channel size requirements: + / - 2.0 mm or less.
(10) vertical kiln wall vertical degree requirements: 2 mm/m or less.
(11) the kiln wall horizontal linearity requirements: 5 mm / 100 m or less.
(12) and horizontal hole brick center roller outer frame structure in the same plane, horizontal hole center deviation of + / - 1.5 mm or less.
(13) accident treatment hole masonry surface smooth, beautiful.
