Embodiment 1

[0035]Embodiment 1: Referring to FIGS. 1 to 6, in Embodiment 1 of the present invention, as shown in FIGS. The length and width of the superimposed surfaces are the same, and the complete superimposition method is adopted, and the connecting bolts 3 are fastened and connected. The laminated wall body 1 is manufactured by drilling copper plates, and the cross-sectional shape V11 of the cooling channel T4 is a compound hole shape or other hole shapes. The base layer wall body 2 is made of cast iron, and has a cooling channel U10 inside, and its cross-sectional shape W12 is a circle or other hole shapes. A gasket 8 is placed between the superimposed layer wall body 1 and the base layer wall body 2. The gasket 8 is a double-layer gasket, and the gap between the double-layer gaskets is filled with a high thermal conductivity filler 9 . The distance from the cooling channel T4 and the cooling channel U10 to the respective wall surfaces is limited to not less than the thickness of t...

Embodiment 2

[0041] Embodiment 2: Referring to Fig. 7, Fig. 8, Fig. 9 and Fig. 10, in Embodiment 2 of the present invention, as shown in Fig. 7, the laminated stave comprises a laminated wall body 1 and a base layer The wall body 2 adopts a partial superimposition method, and the superimposed layer wall body 1 and the upper part of the matrix layer wall body 2 are superimposed. Due to the high temperature in the tuyere area of ​​the blast furnace, if a complete cast iron stave is used, the upper part of the stave is located in the tuyere swirl zone It is easy to be damaged, and the lower part can meet the long life requirements of the blast furnace due to the protection of the refractory material layer; now the laminated stave with independent cooling structure and partial superimposition can be used, which can not only improve the safety of the stave in the tuyere area, but also reduce the thickness of the copper stave. Thickness, reduce cost, embodiment 2 can be used in blast furnace tuye...

Embodiment 3

[0042] Embodiment 3: Referring to Fig. 11, Fig. 12, Fig. 13 and Fig. 14, in Embodiment 3 of the present invention, as shown in Fig. 11, the laminated stave comprises a plurality of laminated wall bodies 1 and a matrix The layer wall body 2 adopts a multi-position superposition method and is fastened and connected by connecting bolts 3 . Adopting this embodiment can achieve the technical effect of matching the local cooling intensity of the cooling stave with the heat flow intensity in the blast furnace. According to the change of the heat flow intensity, copper staves with strong cooling capacity are stacked in areas with high heat flow intensity, which not only meets the cooling needs of the blast furnace, The goal of achieving long life of the blast furnace can also reduce the investment cost; Embodiment 3 can be used for staves in the middle of the blast furnace shaft or other high-temperature wall cooling equipment. All the other conditions and effects of embodiment 3 of t...

Abstract

The laminated cooling wall includes one base wall body layer, one laminated wall layer and one water pipe. The base wall body layer and the laminated wall layer have separate base wall body layer cooling channel U and laminated wall layer cooling channel The with separate water inlets and water outlets. The technological scheme of the present invention has raised cooling effect, saving in copper material, low cost and other beneficial effects.

Description

1. Technical field [0001] The invention belongs to the field of blast furnace and high-temperature wall body cooling equipment, and in particular relates to a laminated cooling wall. 2. Background technology [0002] Changshou blast furnace body cooling equipment must meet the purpose of firmly hanging slag skin on the inner wall of the blast furnace under smelting conditions to form a permanent furnace lining. For this reason, the staves used in blast furnaces are constantly being updated. From the perspective of materials used, they have developed from cast iron staves and cast steel (or steel plate drilling) staves to copper staves with high thermal conductivity. The cast iron stave has poor thermal stability and cannot form a permanent lining, which seriously affects the life of the blast furnace. The pouring temperature of the cast steel cooling stave is high, and the liquefaction of the water pipe surface leads to additional prestress, which is easy to cause cracks in...
