Detailed Description
The invention is further described with reference to the following figures and examples.
The fire-resistant module is integrally prefabricated on the coke oven door in the embodiment and comprises a fire-resistant precast block 1, bolts 2 and heat-resistant steel bars 3, wherein the fire-resistant precast block 1 consists of a block body 11 and an enamel layer 12 positioned on the surface of the block body, and the block body and the enamel layer are sintered into a whole; one part of the bolt is embedded in the fireproof precast block, the other part of the bolt is exposed outside the fireproof precast block, a pin hole 4 is formed in the part of the bolt embedded in the fireproof precast block, the heat-resistant steel bar is embedded in the block body of the fireproof precast block, and the heat-resistant steel bar penetrates through the pin hole in the bolt.
The manufacturing process of the coke oven door integral prefabricated refractory module in the embodiment is as follows:
the heat-resistant steel bars and bolts are fixed in advance in a mould for forming the block body of the fire-resistant precast block, the raw materials of the fire-resistant precast block are stirred and mixed uniformly according to the proportion and then transferred to the mould, then the mould is vibrated to be formed by a vibrating rod, the material in the mould is demoulded after being dried, the outer surface of the block is shaped and coated with glaze after being demoulded, and then the whole precast fire-resistant module of the coke oven door is obtained after baking and firing.
The coke oven door in the embodiment comprises a cast iron door plate 5 and a coke oven door integral prefabricated refractory module, wherein the refractory prefabricated blocks are sequentially arranged on the cast iron door plate, the bolt 2 penetrates through the cast iron door plate 5 and then is connected with a nut 6, and an expansion gap 7 is formed between the end parts of the adjacent refractory prefabricated blocks.
The utility model discloses the whole prefabricated fire-resistant module of well coke oven furnace gate is modular structure, through the bolt can be convenient install on the cast iron door plant of coke oven furnace gate, the installation and construction efficiency is high, also convenient to detach maintenance and change, it is big to have solved the construction and the maintenance intensity of labour that present coke oven furnace gate scene masonry firebrick exists, technical problem that the maintenance cost is high.
Because the surface of the fire-resistant module prefabricated by the coke oven door is sintered with the enamel layer, the surface is smooth and flat, the density is high, and the surface air holes are thinner, so that the surface of the module can prevent chemical erosion in the coking process of the coke oven and is not easy to hang tar, the tar stuck on the surface can be cleaned more easily, the labor intensity of production operators is greatly reduced, and the production efficiency is improved.
In the embodiment, the bolts are connected in series through the heat-resistant steel bars embedded in the overall prefabricated fire-resistant module of the coke oven door, so that the reliability of the bolts is higher, and the installation and use reliability of the overall prefabricated fire-resistant module of the coke oven door is ensured.
In the coke oven door in the embodiment, the expansion gap is formed between the end surfaces of the integrally prefabricated refractory modules of the adjacent coke oven doors, so that the problem of mutual extrusion and damage of the refractory precast blocks caused by high-temperature expansion can be solved.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
