As shown in fig. 1 to 6, the fixing member for the lining brick of the oven door of the coke oven comprises: with 1 assorted fixed steel sheet 2 and first Y type anchor bolt 3 of lining brick body, fixed steel sheet 2 is inboard towards one side of lining brick body 1, the opposite side is the outside, fixed steel sheet 2 goes up to divide left and right two rows of symmetries to be provided with first bolt hole 21, first Y type anchor bolt 3 includes integrated into one piece's first main shaft 31 and two first bifurcations 32, be provided with first fixation nut 33 and movable nut 34 on the first main shaft 31, first main shaft 31 is worn to establish in first bolt hole 21, first fixation nut 33 is located fixed steel sheet 2 inboard and is connected with fixed steel sheet 2, movable nut 34 is located fixed steel sheet 2 outsides, and with first main shaft 31 threaded connection.

In the above technical solution, the fixing steel plate 2 is used to fix the first Y-shaped anchor bolt 3. According to the method, a first Y-shaped anchoring bolt 3 is designed for positioning according to the opening of the edge of the coke oven door, and the first Y-shaped anchoring bolt 3 is ensured to be positioned by precisely opening a hole on a fixed steel plate 2, so that the oven door lining brick is ensured to be fixed on an oven door frame through the first Y-shaped anchoring bolt 3 in a brick body. The first Y-shaped anchor bolt 3 is used for supporting the furnace door lining brick to be matched with a furnace door frame and plays a key role in supporting refractory materials. The first Y-shaped anchor bolt 3 is not a common cylindrical bolt, the end penetrating into the brick body is a forked Y-shaped bolt, and the supporting degree and the stability are higher, so that the service life of the refractory material is ensured.

Furthermore, the first Y-shaped anchor bolt 3 may be made of 304 stainless steel with good ductility, and may be specially processed into an integral non-welding anchor bolt.

Further, in order to secure the fixing action of the fixing steel plate 2 while reducing the weight of the fixing steel plate 2 itself, the fixing steel plate 2 is configured as shown in fig. 1 and 2. The fixed steel plate 2 includes two parallel side steel plates 22 in the same plane and a connecting steel plate 23 disposed between the two side steel plates 22, the connecting steel plate 23 is perpendicular to the side steel plates 22, and the first Y-shaped anchor bolt 3 is disposed on the side steel plates 22.

Further, in order to ensure the overall support of the fixing steel plate 2, a pair of first Y-shaped anchor bolts 3 is provided together with a connecting steel plate 23.

Further, in view of enhancing the coupling action of the first Y-shaped anchor bolt 3 and the brick lining body 1, the angle between the two first diverging arms 32 is 55 ° to 58 °, preferably 56 °.

Because the side of the lining brick body 1 has an inclination, and the cross-sectional structure is a structure with a wide top and a narrow bottom as shown in fig. 4, the extension condition of the first Y-shaped anchor bolt 3 in the lining brick body 1 is further considered, so that the first forked arm 32 of the first Y-shaped anchor bolt 3 is prevented from protruding out of the side of the lining brick body 1, and the first bent part 311 bent towards the inside of the lining brick body 1 is arranged on the first main shaft 31 at the inner side of the fixed steel plate 2, so that the bent first main shaft 31 is parallel to the side of the lining brick body 1.

The number of the first Y-shaped anchor bolts 3 in each row is required to be set according to the specific situation of the opening of the knife edge of the furnace door. Further, each row includes 1 to 3 rows of the first Y-shaped anchor bolts 3.

Further, the first fixing nut 33 and the fixing steel plate 2 are connected by welding. First Y type anchor bolt 3 inlays on fixed steel sheet 2 through welding at the inboard first fixation nut 33 of fixed steel sheet 2, and joint strength is high, avoids first Y type anchor bolt 3 to drop.

Further, in the case that the distance between the two first Y-shaped anchor bolts in the length direction is too large, for example, more than 450mm, another second Y-shaped anchor bolt 4 which is embedded in the fixing steel plate 2 and does not protrude out of the fixing steel plate 2 may be reasonably added between the two, so as to further enhance the connection strength between the fixing steel plate 2 and the lining brick body 1. The number of the second Y-shaped anchor bolts 4 can be specifically set according to practical situations, for example, when the distance between the two first Y-shaped anchor bolts 3 in the length direction is 450-. The second Y-shaped anchor bolts 4 do not protrude from the fixing steel plate 2 because the corresponding furnace door frames of the second Y-shaped anchor bolts 4 have no corresponding openings.

Specifically, a second bolt hole 24 as shown in fig. 5 is provided in the fixing steel plate 2 at a position intermediate between the two first bolt holes 21 or a bolt groove 25 as shown in fig. 6 is provided in the inner wall, and a second Y-shaped anchor bolt 4 is provided in the second bolt hole 24 or the bolt groove 25. The structure of the second Y-anchor bolt 4 is similar to that of the first Y-anchor bolt, and specifically, the second Y-anchor bolt 4 includes a second main shaft 41 and two second bifurcated arms 42 which are integrally formed, a second fixing nut 43 is disposed on the second main shaft 41, the second fixing nut 43 is located inside the fixing steel plate 2 and connected with the fixing steel plate 2, and the end of the second main shaft 41 does not protrude out of the fixing steel plate 2.

Further, the second main shaft 41 is provided with a second bending portion which is bent toward the interior of the lining brick body 1, and the angle of bending of the second bending portion is 10-15 ° similar to the first bending portion 311.

Further, the second Y-anchor bolt 4 is smaller in gauge than the first Y-anchor bolt 3.

In addition, the utility model also provides a lining brick with a fixing piece for the oven door of the coke oven. The coke oven door lining brick with the fixing piece comprises the fixing piece for the coke oven door lining brick, a fixing steel plate 2 is fixed on the surface of a lining brick body 1, which is contacted with an oven door frame, through a first Y-shaped anchoring bolt 3, and the first Y-shaped anchoring bolt 3 is arranged in the lining brick body 1.

The manufacturing method of the furnace door lining brick with the fixing piece comprises the following steps:

the fixing piece for the furnace door lining brick is pre-embedded into the cavity of the pouring mold when the lining brick body 1 is poured and formed, so that the fixing piece and the lining brick body 1 are integrally poured and formed. The pouring product is not sintered at a high temperature of more than 1000 ℃, and the fire-resistant product of the furnace door lining brick can be obtained only by drying and baking treatment at about 500 ℃. It should be understood that the lining brick body 1 of the oven door lining brick with the fixing piece provided by the utility model is a product which is elaborately developed by the applicant and has a special formula, so that the oven door lining brick can be formed only by drying and baking treatment, and the formula is not the focus of the utility model and is not described herein again.

The method for installing the furnace door lining brick with the fixing piece and the furnace door frame comprises the following steps:

when the furnace door lining brick is installed on site, the furnace door lining brick 1 can be fixed on the inner side of the furnace door frame only by inserting one end of the first Y-shaped anchoring bolt 3, which protrudes out of the fixed steel plate 2, into the furnace door knife edge opening and then locking the movable nut 34.
