When construction is carried out on the top or bottom of the furnace, if the construction is improper, the furnace top vault or furnace will occur. Many projects in the project pay great attention to construction factors. Similarly, the construction quality of plastics also directly affects the position of the furnace body . The roof collapses, the bottom of the furnace collapses and other accidents. Therefore, not only the construction quality expected by the plastic manufacturers, but also some plastic users have begun to gradually replace the plastic construction.
During and after construction, the plastics must be: (1) The plastics and the anchoring bricks must be tightly combined; (2) The plastics surface after ramming with an air hammer is smooth, which is not conducive to the gap between the plastics Combine, so when the first layer of material is hammered, the surface needs to be shaved with a scraper to make the bonding surface rough, and then put on the second layer of material, and hammered in the same way; (3) According to the design requirements Cut expansion joints; (4) Punch vents on the plastic after construction; (5) Avoid contact between the plastic lining and water during the maintenance period after the construction of the plastic; (6) Remove the mold as soon as possible before the oven Allow the masonry to dry naturally. After the oven is finished, the places with larger cracks should be filled with refractory fibers to prevent the occurrence of fire-passing phenomenon.
