Description
Technical Field
The utility model relates to the technical field of cooling of the bottom of a blast furnace, in particular to a supporting structure of a water cooling pipe at the bottom of the blast furnace.
Background
The blast furnace uses steel plate as furnace shell, and the inside of the shell is lined with refractory bricks. The blast furnace body is divided into a furnace throat, a furnace body, a furnace waist, a furnace belly and a furnace hearth 5 from top to bottom. The method has the advantages of good technical and economic indexes, simple process, large production quantity, high labor production efficiency, low energy consumption and the like, so that the iron produced by the method accounts for the vast majority of the total world iron yield.
The blast furnace foundation consists of two parts, namely a base buried underground and a foundation pier exposed out of the ground, and has the functions of bearing the force of iron-making equipment and uniformly transmitting the force to the stratum. To ensure sufficient strength and heat resistance of the hearth, cooling of the hearth is a common method.
The Chinese patent publication No. CN201495237U discloses a cooling structure of a blast furnace bottom, which comprises an upper carbon brick and a lower carbon brick which are sequentially arranged from top to bottom, wherein the upper part of the lower carbon brick is provided with a groove, a water cooling pipe is arranged in the groove, and a filler is arranged in a gap between the groove and the water cooling pipe. The furnace bottom is cooled by a water cooling pipe. However, in the application process, the carbon bricks collapse to cause deformation and collapse of the water cooling pipes, and cooling water cannot cool the furnace bottom through the water cooling pipes at the furnace bottom, so that the safety operation of the blast furnace has great hidden trouble.

1) The water-cooled pipe is clamped on the pipe rack through the pipe clamp, and the pipe clamp is fixedly connected with the pipe rack; the upper end of the support frame is fixedly connected with the pipe frame, the lower end of the support frame is fixedly connected with the furnace bottom plate, refractory materials are poured between the lower part of the water cooling pipe and the furnace bottom plate, and the water cooling pipe is contacted with the refractory materials. The high temperature of the furnace bottom is transferred to a water cooling pipe through refractory materials, and is cooled by water cooling.
2) The utility model can reduce the influence of the deformation of the refractory material on the water-cooled tube, i.e. the support structure can resist the deformation of the refractory material and prolong the service life of the water-cooled tube.
3) The utility model adopts an inclined support, one end of which is fixedly connected with the support frame, and the other end of which is fixedly connected with the bottom plate of the furnace. Further increases the stability of the supporting structure, namely further resists the deformation of the refractory material, reduces the deformation of the water-cooled tube and prolongs the service life of the water-cooled tube.

Detailed Description
It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other.
The following is a further description of embodiments of the utility model, taken in conjunction with the accompanying drawings:
The utility model provides a blast furnace bottom water-cooled tube supporting structure which comprises a water-cooled tube 1, a tube clamp 2, a tube rack 3 and a supporting frame 4. The pipe clamp 2 has a U-shaped structure. The water-cooled tube 1 is clamped on the tube rack 3 through the tube clamp 2, and the tube clamp 2 is fixedly connected with the tube rack 3. The upper end of the support frame 4 is fixedly connected with the pipe frame 3, the lower end of the support frame 4 is fixedly connected with the furnace bottom plate 6, a refractory material 7 is poured between the lower part of the water cooling pipe 1 and the furnace bottom plate 5, and the water cooling pipe 1 is contacted with the refractory material 7. The height of the supporting frame 4 is 450-550 mm.
Refractory material 7 is poured between the water cooling pipe 1 and the furnace bottom plate 6 because the furnace bottom temperature is high, up to about 1000 degrees celsius, and if the water cooling pipe 1 contacts the furnace bottom plate 6, the service life of the water cooling light pipe 1 is reduced. If a space is left between the water cooling pipe 1 and the furnace bottom plate 6, the cooling effect of the water cooling pipe 1 on the furnace bottom is affected. The poured refractory material 7 thus acts to insulate and conduct heat. The cast refractory has a longer service life and a lesser degree of collapse and deformation than a masonry refractory carbon brick.
The height of the supporting frame 4 is 450-550 mm. The support frame 4 is too high, can influence the cooling effect of water-cooled tube 1, and support frame 4 is too low, and water-cooled tube 1 is little apart from stove bottom plate 6 distance, and the high temperature of stove bottom plate 6 can reduce the life of water-cooled tube 1.
The utility model provides a blast furnace bottom water-cooled tube bearing structure, still includes bearing diagonal 5, bearing diagonal 5 one end and support frame 4 fixed connection, the other end and stove bottom plate 6 fixed connection. Further increasing the stability of the support structure, i.e. further resisting deformation of the refractory material 7, reducing deformation of the water-cooled tube 1 and prolonging the service life of the water-cooled tube 1.
The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present utility model within the scope of the technical concept of the present utility model, and all the simple modifications belong to the protection scope of the present utility model. In addition, the specific features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various possible combinations are not described further. Moreover, any combination of the various embodiments of the utility model can be made without departing from the spirit of the utility model, which should also be considered as disclosed herein.
