[0018] In this article, terms such as "inner," "outer," "upper," and "lower" are established based on the positional relationships shown in the attached drawings. Depending on the attached drawings, the corresponding positional relationships may also change. Therefore, they should not be interpreted as an absolute limitation on the scope of protection.

[0019] Example 1: Combined with appendix Figure 1 - Appendix Figure 4 This invention provides a composite integral furnace lining, comprising a furnace body 1 and a stove ring 2. A refractory clay lining 3 is fixed to the inner wall of the furnace body 1. A stove head assembly port 9, penetrating both the furnace body 1 and the refractory clay lining 3, is located at the bottom of the furnace body 1. The stove ring 2 is installed on the top of the furnace body 1. During manufacturing, refractory clay is placed inside the furnace body 1 and molded. After the refractory clay dries, it is simultaneously molded and connected to the furnace body 1, resulting in a durable, energy-efficient, and well-integrated structure. Specifically, the furnace body 1 can be made of ductile iron. During manufacturing, the furnace body 1 serves as the outer mold, and an inner mold, representing the internal shape of the refractory clay lining 3, is installed on a hydraulic device. The hydraulic device with the inner mold is used to press the refractory clay inside the furnace body 1, forming the refractory clay lining 3. Through the high-pressure densification process of the hydraulic device, the furnace body 1 and the refractory clay lining 3 are structurally integrated, significantly improving the material's bulk density and overall structural strength. Furthermore, the inner wall of the furnace does not crack or peel off, further achieving a durable effect.

[0020] Specifically, the stove ring 2 has multiple second bolt holes 5 along its circumference, and the top of the furnace body 1 has first mounting holes 7 corresponding to the number and position of the second bolt holes 5. The stove ring 2 and the furnace body 1 are fixedly connected by bolts that fit with the second bolt holes 5 and the first mounting holes 7. When connecting the stove ring 2 to the furnace body 1, the second bolt holes 5 on the stove ring 2 are aligned with the positions of the first mounting holes 7 on the top of the furnace body 1. The threaded end of the bolt is passed through the first mounting hole 7 and screwed into the second bolt hole 5. After tightening the bolt, the installation of the stove ring 2 is completed. When connecting the furnace to the burner, the first bolt holes 4 are aligned with the mounting holes on the burner flange. The connection between the furnace and the burner is achieved by passing a bolt through the mounting hole and screwing it into the first bolt hole 4.

[0021] Specifically, the stove ring 2 has multiple connecting holes 6 along its circumference, each connecting hole 6 located between two adjacent second bolt holes 5. The top of the furnace body 1 has a second mounting hole 8 corresponding to the number and position of the connecting holes 6. The user can align the connecting holes 6 and the second mounting holes 8 with the bolt holes on the stove surface, pass the threaded end of the connecting bolt through the connecting holes 6 and the second mounting holes 8 in sequence, and then screw it into the bolt hole, tightening it to connect the furnace to the stove surface. The location of each connecting hole 6 between two adjacent second bolt holes 5 ensures the uniformity of the connection points between the stove ring 2 and the furnace body 1, and between the furnace and the stove surface, guaranteeing a good connection.

[0022] More specifically, the connecting hole 6 penetrates the stove ring 2, and the second bolt hole 5 is located at the bottom of the stove ring 2 and does not penetrate the stove ring 2.

[0023] Specifically, a burner bushing 10 is inserted into the burner mounting opening 9. The burner bushing 10 fills the gap between the burner and the inner wall of the burner mounting opening 9 in the furnace, preventing backfire. More specifically, the burner bushing 10 has a flange 11 at its top, and the radial dimension of the flange 11 is larger than the diameter of the burner mounting opening 9. When installing the burner bushing 10, the bottom of the burner bushing 10 is inserted into the burner mounting opening 9 from the furnace body 1 until the flange 11 contacts the bottom wall of the refractory mud furnace 3. At this point, the burner bushing 10 cannot move further downward under the limiting effect of the flange 11, thus achieving placement in the furnace. Compared to directly setting the burner mounting opening 9, setting the burner bushing 10 in the burner mounting opening 9 is more aesthetically pleasing. More specifically, a first bolt hole 4 for connecting to the burner is provided at the bottom of the furnace body 1, that is, the bottom of the burner bushing 10 has multiple first bolt holes 4. The first bolt hole 4 is set at the bottom of the stove head bushing 10. When installing the furnace, the first bolt hole 4 is aligned with the mounting hole on the stove head flange. The bolt is passed through the mounting hole and screwed into the first bolt hole 4. After tightening the bolt, the furnace body 1 and the bottom wall of the refractory mud furnace 3 are clamped between the flange 11 of the stove head bushing 10 and the stove head flange, thus realizing the connection between the furnace and the stove head.

[0024] Specifically, the bottom of the stove ring 2 is provided with a filling groove 13. The top of the refractory mud chamber 3 and the furnace body 1 covers the bottom filling groove 13 of the stove ring 2, forming a filling cavity 12, which is filled with refractory mud. When installing the stove ring 2 and the furnace body 1, the stove ring 2 is placed upside down on the workbench, and then refractory mud is filled into the filling groove 13. After filling, the furnace body 1, with the refractory mud chamber 3 formed inside, is placed upside down on the stove ring 2, so that the top of the furnace body 1 and the refractory mud chamber 3 covers the bottom filling groove 13 of the stove ring 2. The stove ring 2 achieves a preliminary connection with the furnace body 1 and the refractory mud chamber 3. Then, the bolts are screwed into the second bolt holes 5 to complete the installation of the stove ring 2. The refractory mud filling in the filling cavity 12 can strengthen the connection between the stove ring 2 and the furnace body 1 and the refractory mud chamber 3, and improve the integrity of the furnace.

[0025] Specifically, the inner edge of the top of the refractory mud chamber 3 is provided with a groove, and the bottom of the inner edge of the stove ring 2 is provided with a snap-fit ​​edge that matches the groove, and the snap-fit ​​edge is located inside the groove.

[0026] Example 2: Combined with appendix Figure 5 and attached Figure 6 This invention provides a composite integral furnace in Embodiment 2. The composite integral furnace in this embodiment has the same basic structural properties as the composite integral furnace in Embodiment 1. The difference is that the bottom of the furnace body 1 in this embodiment is provided with a plurality of protrusions 14 along the circumferential direction, and the first bolt hole 4 is provided in the protrusions 14.

[0027] The furnace can be connected to the burner head via the first bolt hole 4 at the bottom of the burner head bushing 10 and / or the bottom of the furnace body 1.
