Problems solved by technology

This method is inaccurate in the positioning of the upper and lower intersection points of the formed shell, the deviation of the intersection points between the upper and lower openings is large, and the quality of the product is accurate. Subsequent workers need to adjust the intersection points of the upper and lower openings of the shell, and the work efficiency is low.

Embodiment 1

[0036] Such as figure 1 , 2 As shown, the furnace cap has a C-shaped bend, the height is 2968mm, the inner wall R=3820mm, the wall thickness is 30mm, the upper mouth radius of the shell 1 is 3760mm, and the lower mouth radius is 1195mm.

[0037] Such as image 3 As shown, the furnace cap C-shaped curved shell is made according to the design drawing and divided into 9 shell tiles 2 in the shape of melon petals. Each shell tile 2 has a machining allowance of not less than 50mm. In this embodiment, the machining allowances around the shell tiles 2 are respectively 50mm, and the compression molding is performed on the press, and the arch is checked by the template during the compression molding process.

[0038] Such as Figure 4 As shown, after the shell tiles 2 are press-formed to pass, the 50mm margin reserved at the vertical seam is cut off, and then the vertical construction site break is cut according to the drawings.

[0039] Follow the steps below to install:

[0040] A, such as ...

Embodiment 2

[0051] Such as Figure 8 As shown, the tapered shell is equally divided into 4 shell tiles 2 with a tapered structure. The lower mouth radius of the tapered shell is 6085mm, the height is 2980mm, the upper mouth radius of the tapered shell is 5525mm, and the thickness It is 30mm.

[0052] Follow the steps below to install the conical shell:

[0053] A. Mark the bottom circle 3 of the shell 1 on the floor, and mark the center point of the bottom circle 3. The center point of the bottom circle 3 is the projection point of the center point of the upper and lower mouths of the shell 1; set 0° , 90°, 180°, 270° cross lines are drawn on the bottom circle 3; the projection line of the shell 1 vertical seam on the bottom circle 3 is "aligned" with the cross center line of the bottom circle 3. One half of the size of the vertical seam of the shell tiles is reserved on the side; a leveling pad 5 is set at the vertical seam of the shell 1, and the upper surface of the leveling pad 5 has the ...

Abstract

The invention relates to the field of steel structure shell machining, in particular to a method for assembling, processing and manufacturing a shell in a workshop. A shell bottom circle is marked ona floor according to the size of the shell, a leveling cushion block is arranged on the bottom circle line, a vertical rod is arranged beside the circle center point of the bottom circle, a gradienterand a plumb bob are arranged on the vertical rod, shell tiles are assembled on the leveling cushion block, the circle centers of the upper and lower openings of the shell are determined, the verticality of the upper and lower opening radiuses of the shell tiles is measured, and other shell tiles are assembled. According to the method, the shell assembling precision can be effectively controlled,the construction precision requirement is guaranteed, the time cost of assembling personnel is reduced, and the construction efficiency is improved.

Description

Technical field [0001] The invention relates to the processing field of steel structure shells, in particular to a method for assembly processing of shell workshops. Background technique [0002] Steel structures such as hot blast furnaces and blast furnaces generally consist of straight sections, cone sections, C-section bends, and hemispherical furnace caps from bottom to top. The existing factory assembly uses thin steel wires at the upper and lower mouths of each section of the shell. A number of thin steel wires form an intersection in the middle, and a wire drop is hung at the intersection to align with the middle dot of the shell, and subsequent adjustments and inspections are performed. This method is inaccurate in the positioning of the upper and lower mouth intersection points of the formed shell, the upper and lower mouth intersection points have large deviations, and the quality of the product is accurate. Follow-up workers need to adjust the upper and lower mouth int...
