(1) On the basis of the qualified acceptance of the pool bottom steel structure, the best way is to lay out the relevant feeding port, the front and rear rows of bubbles and the center line of each wire drawing plate on the forming passage according to the kiln construction baseline and the kiln center line, and maintain the stable first position in China for a long time.
(2) Pool bottom masonry, including the passage bottom. After laying the insulation bricks and kaolin bricks, widen the inside and outside of the pool wall by 30-50mm for leveling. The multi-layer underground structure must be controlled according to the negative deviation of the elevation during masonry, and the allowable deviation of the total thickness of the pool bottom is generally -3mm. A layer of chrome ramming material is laid on the kaolin bricks at the bottom of the pool as a sealing layer to prevent the glass liquid from penetrating into the clay brick layer with poor corrosion resistance.
(3) Pool wall masonry, including the passage pool wall. The bottom bricks of the pool wall must be level, otherwise the bottom bricks of this part must be processed until the requirements are met. When laying bricks for multi-layer pool walls, the inside should be laid first and then the outside. The dimensions of the furnace should be ensured. It is strictly forbidden to face the cut surface of the bricks towards the furnace. The corners should be laid with staggered joints and the verticality should be strictly maintained.
(4) Lifting columns. Take temporary measures to stabilize the columns, and then install the slag angle steel according to the design requirements. The columns and slag angle steel must be close together, and the elevation should be determined at the same time.
(5) Laying down the arch. Make the arch base, and after the arch frame is subjected to the load settlement test and the corresponding size inspection, the arch is laid from both sides to the center at the same time, and continuous operation is required. The insulation layer of the arch is constructed after the kiln is baked.
(6) Laying down the breast wall, front wall, rear wall and passage flame space. The laying of the breast wall should be carried out after carefully checking that the bracket, support plate and support frame are installed properly. When laying the hook bricks and breast wall bricks, measures should be taken to prevent them from tipping into the kiln.
(7) Laying down the flue and chimney. The masonry must be carried out after the debris in the kiln is cleared and vacuumed. The masonry of the furnace flue and chimney must be coordinated with the metal heat exchanger. The passage chimney must be built after the passage is built.
(8) There are two masonry methods: dry masonry and wet masonry.
Dry masonry parts: the bottom and wall of the melting part and the passage, the hook bricks in the flame space, the arch bricks of the melting part and the flue, the electric melting brick masonry and the passage roof bricks.
Wet masonry parts: the side walls and arch top of the melting part flame space, the insulation bricks of the flue, chimney and kiln. The mud used for wet masonry should be prepared according to the refractory bricks used.
