Description
Technical Field
The utility model belongs to the mould industry, and belongs to a novel machine press forming mould for prefabricated bricks of a coke oven door.
Background
The prefabricated brick for the oven door of the coke oven is used in places with severe temperature changes, so the brick is required to have good heat insulation performance, low expansion characteristic, good adhesion and long service life.
The prefabricated bricks on the coke oven door have larger size and higher process requirement, and a large amount of bonding agents are not suitable for the green brick materials, so the machine pressing forming difficulty is very high, wood dies are mostly adopted for vibration forming or beating forming, but the green brick strength formed by the wood dies is far lower than that formed by the machine pressing forming, so the green brick entity formed by the wood dies is mostly of a solid structure and rarely adopts a complex cavity or a hollow structure, so the labor cost is greatly increased, and a lot of instability of the forming process is also caused.
The solid green bricks formed by adopting the wood mould have the following defects in the actual forming, drying and sintering processes and even the use process:
1. the green brick formed by the wood mold has low strength, uneven density and invisibility, the difficulty of drying and sintering processes is increased invisibly, and if the drying is not thorough and even the sintering crystalline phase in the brick body is asynchronous, the spalling in the brick body is easily formed, thereby influencing the service life of the brick;
2. as most adobes formed by the wood mold adopt a solid structure, the adobes need to enter a drying kiln for drying for a longer time so as to ensure that the moisture in the adobes is thoroughly discharged, and the time cost is invisibly increased;
3. because the green bricks formed by the wood mold are mostly of solid structures, the green bricks are carried by manpower heavily from the forming to the drying, sintering and other links, and because the green bricks formed by the wood mold have far lower strength than the green bricks formed by organic pressure, the green bricks are easy to knock edges and fall corners to cause extra scrap in the carrying process;
4. the wood mould for wood mould forming is wood, and can deform after long-time working, so that green bricks are scrapped due to green brick size deviation;
finally, even if the sintering size of the green brick with the solid structure formed by the wood mold is qualified, all processes meet the use requirements, and the green brick serving as the lining brick of the coke oven door is extremely labor-consuming for people to carry and install during installation and masonry.
Due to the above disadvantages, a novel machine pressing mold for the prefabricated bricks of the coke oven door is needed, which requires to be formed on a machine table in a machine pressing manner, so as to ensure the strength of the brick blank, and simultaneously realize the hollow structure of the formed brick blank, thereby greatly reducing the weight of the brick body.
