Laboratory furnace, furnace masonry and methods of the basic sequence is as follows:
① bottom masonry, including the passage at the end. Qi Hao large brick insulation brick and kaolin after the masonry wall at the inside and outside to relax 30-50mm leveling. Multilayer structure underground masonry elevation negative deviation must be controlled, the bottom of the total thickness tolerances generally-3mm. In the bottom layer of kaolin large brick laying above chrome ramming as a sealing layer to prevent liquid penetration to the corrosion resistance of glass poor clay layer.
② In the bottom steel structure on the basis of acceptance, according to the baseline and experimental furnace construction furnace, furnace centerline release related to feeding port, front and rear bubbling and forming pathway of Taiwan brushed drain board centerline.
③ lifting column. Interim measures to stabilize the column, and then install the ballast ballast according to design requirements angles, columns and ballast ballast angle must be close to the same time determined the exact elevation.
④ masonry wall, including the passage wall. The bottom brick masonry wall must ensure that the level of degree, or to the bottom of the tile area for processing until it reaches the requirements. Multi-wall brick building, the first in the field after the operation to make sure the
furnace size, non-timber hewn side facing brick hearth. Masonry joints to be staggered corner pressure, strictly maintain verticality.
⑤ masonry parapet, the front wall, back wall and channel flame space. Masonry parapet bracket should be carefully examined, pallets and bearers installed after passing. Masonry brick and chest wall hooks have taken measures to prevent the dumping of the kiln.
⑥ big arch masonry. Production arch tires, do carry through gantry sedimentation test and check the corresponding size, the big arch masonry to the center from both sides simultaneously, and requires continuous operation, try to control! * + Complete. Large arch insulation layer construction after the end of the kiln to be baked.
⑦ masonry flue, chimney. Kiln debris must be cleared, and with a vacuum cleaner after masonry. Laboratory furnace, furnace flue and chimney masonry, but also compatible with the metal heat exchanger, access paths masonry chimney must be completed before other masonry.
Is there any way masonry kilns?
Masonry method of wet and dry assemble puzzle two ways:
Wet puzzle parts: the Ministry of flames melted the side walls and arch roof space, flue, chimney and furnace insulation bricks, masonry used in the wet mud should be based on material used in the preparation of the corresponding fire clay bricks.
Dry assemble parts: melting section and the bottom path, wall, brick fire space parts of the hook, melting section and flue arch arch bricks, fused brick and path roof tiles.
Well-designed laboratory furnace, furnace, must be carefully masonry, masonry quality for life of the furnace, fuel consumption, glass melting and drawing operations has a significant impact.
