What are the requirements for masonry refractory bricks in float glass kiln heat storage chambers?

The masonry of the float glass kiln is based on the longitudinal centerline of the kiln, the centerline of the 1# small furnace and the elevation. Glass kiln flue and heat storage chamber refractory brick masonry requirements are briefly described below.

(1) flue

① float glass kiln flue generally in the kiln masonry stage masonry, but some manufacturers in order to catch up with the ignition time, and will be built after the kiln main body, and then carry out the masonry of the flue, at this time should pay attention to the construction of protection.

② flue construction to 1 # small furnace centerline and kiln centerline as a reference, for convenience, in the total flue and branch flue junction, branch flue corner of the swan processing, can be used for heat-resistant concrete casting.

③ In the flue where different swan spans meet, the swan is constructed with straight seam masonry, and the wall should be constructed with staggered seam masonry, at this time, attention should be paid to the length of the swan bricks at the head of the swan is not less than 120mm, so as not to dislodge the bricks of the head of the swan.

④The expansion joints of the flue wall shall be set up in sections, generally every 2m shall be set up according to 8mm, the expansion joints shall be masonry with staggered joints, and the expansion joints shall be masonry with clay bricks, and the insulating bricks shall not be used.

⑤ flue wall outside a layer of red brick, due to the thickness of red bricks and standard refractory bricks are different, masonry is not matched, so every 7-8 layers of red bricks are required to bite half a brick to the wall, can be processed through the thickness of insulation bricks to adjust the height of the bite at the masonry.

(2) Heat storage room

① heat storage room wall thickness is generally 578mm, of which the side wall and end wall by a brick and a half of refractory bricks and insulation bricks a brick composition, masonry expansion joints can be left in sections. Partition wall is composed of all refractory bricks (two and a half bricks), expansion joints must be left at the ends of the partition wall.

② furnace strip swan is the key part of the heat storage room, must ensure safety, must be pulled through the line of swanning, each furnace strip swan can not be skewed. Furnace swan brick with leveling bricks to level, leveling bricks on the surface to strive for flat, in order to facilitate the lattice brick yards. Float glass melting kiln furnace bar swan leveling work time is long, must be fine construction. Currently the common method is to level the lower surface of the brick processing suitable with mud masonry. After masonry, according to the furnace strip swan brick leveling bricks required elevation bouncing line, and each brick will be numbered after the leveling bricks will be removed, in accordance with the bouncing line marks cut, and then according to the numbered position of the mud masonry again, according to the elevation of the line, with the angular grinding to correct the height.

③The back side wall of heat storage room should be suspended after it is built to the height of the bottom plate of small furnace to carry out the construction of chest wall and small furnace, and the construction of back side wall can be continued only after the masonry of small furnace diagonal swan and back flat swan is finished.

The lattice bricks should be vertical and horizontal, and the lattice bricks should be packed in boxes according to the positive and negative tolerances after production inspection, and the tolerance range should be marked on the boxes. The same layer of lattice bricks is required to use the same tolerance range of lattice bricks in yard laying.
