[0035] Before describing the embodiments of the present invention in detail, the application environment of the present invention will be described first. The technology of the present invention is mainly applied in the field of equipment maintenance technology. The present invention is used to solve the problem that the sealing insulation cover of the existing walking beam furnace cannot be replaced as a whole.

[0036] Please combine Figures 1 to 8 As shown, the present invention provides a split-type heat insulation cover for a walking beam furnace, comprising:

[0037] In an exemplary embodiment of this application, the split-type heat insulation cover 1 includes a first heat insulation cover split 101 and a second heat insulation cover split 102; both the first heat insulation cover split 101 and the second heat insulation cover split 102 include an outer shell 2 and an internal filling cavity 3 formed by the outer shell 2; the outer shell 2 includes a top plate 201, multiple side plates 202 and multiple bottom plates 203, the top plate 201 has a mounting groove 201a for installing water beam columns, and one side edge of the top plate 201 has a first notch 201b, the first notch 201b and the mounting groove 203 are connected. 01a is connected, multiple side panels 202 are connected to the edge of the top plate 201 and form a second notch 202a. The second notch 202a is connected to the first notch 201b and is located on the same side. Multiple bottom plates 203 are respectively connected to the end of the multiple side panels 202 away from the top plate 201. The bottom plates extend toward the side away from the mounting groove 201a. An internal filling cavity 3 is formed in the area enclosed by the top plate 201 and the multiple side panels 202. The second notch 202a is used to connect and fix the first insulation cover split 101 and the second insulation cover split 102.

[0038] In this embodiment, the first insulation cover component 101 and the second insulation cover component 102 have completely similar structures. The first insulation cover component 101 and the second insulation cover component 102 cooperate to form a set of split insulation covers 1 for replacing the original sealing insulation cover. The mounting groove 201a is a through groove opened along the thickness direction through the top plate 201. The mounting groove 201a is a "U"-shaped groove, and the opening of the "U"-shaped groove extends to one side edge of the top plate 201. The split insulation cover 1 includes three side panels 202. The side panels 202 are perpendicular to the top plate 201, and one side edge of the side panel 202 is fixed to one side edge of the top plate 201 by welding, and avoids... The installation groove 201a is connected to the side panel 202 at the "opening" (i.e., the first notch 201b) to reserve an installation area for cooperating with the water beam column, which is the second notch 202a. The bottom plate 203 includes three pieces, each of which corresponds to one side panel 202 and is fixed to the edge of the side panel 202 away from the top plate 201 by welding. The bottom plate 203 extends toward the side away from the installation groove 201a. The bottom plate 203, the top plate 201 and the side panel 202 form the outer shell 2 and simultaneously form the installation area for cooperating with the installation of the water beam column and the internal filling cavity 3 for filling with refractory filler. By adopting the above technical solution, when it is necessary to replace the original sealing insulation cover, it is only necessary to destructively remove the original sealing insulation cover, and then install the first insulation cover part 101 and the second insulation cover part 102 with the water beam column to complete the replacement of the sealing insulation cover. By adopting the technical solution of this application, the sealing insulation cover can be replaced online without replacing the water beam column, effectively solving the maintenance problem of inconsistent service life between the water beam column and the sealing cover, thereby having the beneficial effects of reducing maintenance costs and improving maintenance efficiency. In an exemplary embodiment of this application, multiple anchor nails 202b are provided on multiple side panels 202.

[0039] In this embodiment, anchor nails 202b are provided on the side panel 202 to improve the stability and structural strength of the side panel 202, which can effectively improve the load-bearing capacity of the side panel 202.

[0040] In one exemplary embodiment of this application, a plurality of anchor pins 202b are located within the internal filling cavity 3.

[0041] In this embodiment, when pouring refractory material into the internal filling cavity 3, the refractory material molding includes the anchoring nail 202b, thereby effectively improving the structural strength of the molded refractory material.

[0042] In an exemplary embodiment of this application, the plurality of anchor pins 202b are in a “Y” shape.

[0043] In this embodiment, setting the anchor 202b as a Y-shaped structure effectively increases its stability. The Y-shaped structure provides a larger support area, making the anchor 202b more stable. It also increases the strength and stiffness of the anchor 202b, enabling it to withstand greater loads. Under tensile or shear forces, the Y-shaped structure provides better tensile and shear performance, making the anchor 202b more reliable and stable. The Y-shaped structure of the anchor 202b can evenly distribute the load across multiple anchors, reducing the possibility of excessive stress on a single anchor 202b, thereby reducing the risk of stress concentration and failure. The Y-shaped structure can reduce the deformation and fatigue of the anchor, extending the service life of the anchor 202b.

[0044] In an exemplary embodiment of this application, the top plate 201 has a mounting hole 201c that is opposite to the slotted area of ​​the mounting groove 201a along the length direction.

[0045] In this embodiment, the top plate 201 has a mounting hole 201c in the slotted area away from the mounting groove 201a along the length direction. The mounting hole 201c is a thermal expansion hole, and the water beam column is installed by fitting with the mounting hole 201c through expansion bolts.

[0046] In an exemplary embodiment of this application, a first reinforcing structure 4 is provided at the connection between the top plate 201 and the side plate 202.

[0047] In this embodiment, the first reinforcing structure 4 is a trapezoidal structure. By setting the first reinforcing structure 4 on the inner side of the internal filling cavity 3 between the connection between the top plate 201 and the side plate 202, the structural strength of the outer shell 2 is effectively improved, thereby avoiding the risk of deformation of the top plate 201 and the side plate 202 at the connection.

[0048] In an exemplary embodiment of this application, a second reinforcing structure 5 is provided at the connection between the base plate 203 and the side panel.

[0049] In this embodiment, the second reinforcing structure 5 is a "rectangular" structure. By setting the second reinforcing structure 5 at the connection between the bottom plate 203 and the side plate 202, the structural strength of the outer shell 2 is further improved, avoiding the risk of deformation at the connection between the bottom plate 203 and the side plate 202.

[0050] like Figure 9 As shown, this application also proposes an installation method for a separate insulation cover 1 for a walking beam furnace, including a separate insulation cover 1 for a walking beam furnace.

[0051] Figure 9 This is a flowchart of the installation method of the split-type heat insulation cover 1 of the step-type heating furnace proposed in this application.

[0052] In an exemplary embodiment of this application, the method includes at least steps S110 to S140.

[0053] Step S110: Refractory material is poured offline in the internal filling cavity 3 of the split-type heat insulation cover 1.

[0054] Step S120: Remove the original sealing and insulation cover.

[0055] Step S130: Install the mounting grooves 201a on the first insulation cover 101 and the second insulation cover 102 with the water beam column.

[0056] In step S140, the first heat insulation cover detachment 101 and the second heat insulation cover detachment 102 are fixed by welding at the second notch 202a.

[0057] Working principle: The first insulation cover component 101 and the second insulation cover component 102 cooperate to form a set of split insulation covers 1 for replacing the original sealed insulation cover. The mounting groove 201a is a through groove opened along the thickness direction through the top plate 201. The mounting groove 201a is a "U"-shaped groove, and the opening of the "U"-shaped groove extends to one side edge of the top plate 201. The split insulation cover 1 includes three side panels 202. The side panels 202 are perpendicular to the top plate 201, and one side edge of the side panel 202 is fixed to one side edge of the top plate 201 by welding, avoiding the "opening" of the mounting groove 201a. The first notch 201b is connected to the side panel 202, thereby reserving an installation area for cooperating with the water beam column, which forms the second notch 202a. The bottom plate 203 includes three pieces, each bottom plate 203 corresponding to one side panel 202, and is fixed to the edge of the side panel 202 away from the top plate 201 by welding. The bottom plate 203 extends toward the side away from the installation groove 201a. The bottom plate 203, the top plate 201 and the side panel 202 form the outer shell 2, and at the same time form the installation area for cooperating with the installation of the water beam column, and the internal filling cavity 3 for filling refractory filler. By adopting the above technical solution, when it is necessary to replace the original sealing and insulation cover, it is only necessary to destructively remove the original sealing and insulation cover, and then install the first insulation cover part 101 and the second insulation cover part 102 with the water beam column to complete the replacement of the sealing and insulation cover. By adopting the technical solution of this application, the sealing and insulation cover can be replaced online without replacing the water beam column, which effectively solves the maintenance problem of inconsistent service life between the water beam column and the sealing cover, thus having the beneficial effects of reducing maintenance costs and improving maintenance efficiency.

[0058] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
