For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] Figure 1 The image shown is a front view of the casting mold and vacuum tank impregnation tube of this utility model. The following description uses… Figure 1 For reference, the extension direction of the impregnation tube 3 is defined as the up-down direction, and the top beam 11 is located above the bottom plate 12; the distribution direction of the two impregnation tubes 3 is defined as the left-right direction, the direction perpendicular to the up-down and left-right directions is defined as the front-back direction, and the two top beams 11 are distributed along the front-back direction.

[0040] like Figures 1-4As shown, the utility model provides a kind of refractory pouring mold between vacuum tank impregnation pipe, this pouring mold 1 is installed between the two impregnation pipes 3 of the bottom connection of vacuum tank 4, including a bottom plate 12, two roof beams 11 and two side baffle 14.Two roof beams 11 are respectively straddled between the upper surface of two impregnation pipes 3, and each roof beam 11 is detachably connected with the front side or rear side of bottom plate 12 by a connecting piece 15, and bottom plate 12 is attached to the lower surface of two impregnation pipes 3.By setting roof beam 11, the relative position of bottom plate 12 between two impregnation pipes 3 is fixed, and the bottom surface of pouring mold 1 is formed.

[0041] Specifically, connecting hole 111 is provided on roof beam 11 and matched with connecting piece 15, and the front side and rear side of bottom plate 12 are both provided with connecting groove 121 matched with connecting piece 15, and connecting piece 15 is detachably connected with connecting hole 111 and connecting groove 121 by bolt.It is preferred that connecting piece 15 is connecting rod. Those skilled in the art can replace the shape of connecting piece 15 with plate, block or other shapes according to needs. Through the cooperation of connecting hole 111, connecting groove 121 and connecting piece 15, the installation and disassembly process of pouring mold 1 becomes more convenient and efficient, reduces the operation difficulty and time cost, and at the same time makes pouring mold 1 adapt to impregnation pipes 3 of different sizes, improves the versatility and flexibility of pouring mold 1.

[0042] Each side baffle 14 is vertically arranged between two impregnation pipes 3 and abuts against two impregnation pipes 3, and the bottom of each side baffle 14 is detachably connected with the front side or rear side of bottom plate 12. A tension rod 16 extending in front-back direction is detachably connected between two side baffles 14, and the connecting position of tension rod 16 and each side baffle 14 is arranged on the side of each side baffle 14 close to roof beam 11. Thus, the bottom and top of side baffle 14 are limited, the relative position of side baffle 14 between two impregnation pipes 3 is fixed, and side baffle 14 is tightly attached to two impregnation pipes 3, forming two side surfaces of pouring mold 1.

[0043] Specifically, as shown, Figure 2 The front side and rear side of bottom plate 12 are each provided with a stopper 122, and each side baffle 14 is installed inside one of stoppers 122, and the bottom abuts against stopper 122. Tension rod 16 and stopper 122 limit side baffle 14 in front-back direction respectively, so that side baffle 14 tightly abuts against two impregnation pipes 3 and cannot move, effectively enhancing the stability of side baffle 14, preventing side baffle 14 from shifting during refractory pouring.

[0044] As shown, Figures 1-4As shown, a cavity for pouring the refractory 2 is surrounded between the two side plates 14, the bottom plate 12 and the two impregnation pipes 3, and the pouring mold 1 is tightly fitted with the impregnation pipes 3 to ensure the stability of the cavity structure, and further ensure the uniformity and compactness of the refractory 2 poured in the cavity.

[0045] The pouring mold 1 further comprises a reinforcing bar 13 which is arranged between the upper surfaces of the two impregnation pipes 3 and extends downward in the vertical direction into the cavity, and is used to connect the refractory 2 and the two impregnation pipes 3, so as to enhance the bonding force between the refractory 2 and the impregnation pipes 3, make the connection structure of the refractory 2 and the two impregnation pipes 3 more stable, and enhance the anti-falling performance of the refractory 2.

[0046] Specifically, the bottom of the reinforcing bar 13 is spaced apart from the bottom plate 12. The gap can reduce the direct heat conduction between the bottom plate 12 and the reinforcing bar 13, help to reduce the temperature of the bottom plate 12, and protect the material of the bottom plate 12 from high temperature.

[0047] Specifically, the reinforcing bar 13 comprises a first horizontal section 131 arranged between the upper surfaces of the two impregnation pipes 3, a vertical section 132 extending downward in the vertical direction into the cavity, and a second horizontal section 133 connected to the bottom of the vertical section 132. Through the combination of the first horizontal section 131 and the vertical section 132, the reinforcing bar 13 connects the refractory 2 and the upper surfaces of the impregnation pipes 3, and helps the refractory 2 to resist the falling tendency caused by gravity. The second horizontal section 133 increases the connection area of the refractory 2 and the reinforcing bar 13, so that the connection structure of the refractory 2 and the two impregnation pipes 3 is more stable.

[0048] The construction process of the pouring mold 1 is as follows:

[0049] S1: First, the two roof beams 11 are arranged between the upper surfaces of the two impregnation pipes 3;

[0050] S2: The bottom plate 12 is fitted to the lower surfaces of the two impregnation pipes 3;

[0051] S3: The reinforcing bar 13 is arranged between the upper surfaces of the two impregnation pipes 3;

[0052] S4: The two side plates 14 are respectively placed on the inner sides of the two stop blocks 122, and respectively abut against the side surfaces of the two impregnation pipes 3;

[0053] S5: The connecting piece 15 is used to connect each roof beam 11 and the bottom plate 12.

[0054] S6: The tension rod 16 is inserted into the two side plates 14, the two side plates 14 are tightened, and the bolts are tightened;

[0055] S7: After the installation of the mold 1, the uncured refractory 2 is poured into the cavity of the mold 1, and the pouring height of the uncured refractory 2 is not less than the height of the middle part of the tension reinforcement 13;

[0056] S7: After the pouring of the uncured refractory 2 is completed, the uncured refractory 2 is maintained, and then the two top beams 11, the bottom plate 12, the two side plates 14, the tension rods 16 and the connecting pieces 15 are removed and cleaned.

[0057] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
