Description

Technical Field

[0001] This utility model belongs to the field of pyrometallurgical furnace and kiln equipment, specifically relating to a steel structure device for a side-blown furnace body. Background Technology

[0002] Traditional side-blown furnaces have complex steel structures with numerous intersecting components, increasing manufacturing and installation difficulty and costs, and creating problems for later maintenance. The original furnace hearth lateral deformation was constrained by a single clamping beam, resulting in a cumbersome structure, poor control, and an irrational layout of the operating space that restricted operator movement, impacting daily operation and equipment maintenance efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a steel structure device for a side-blown furnace body, which aims to solve the problems of the furnace body steel structure being not simplified and the control effect being poor in the above-mentioned background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A steel structure device for a side-blown furnace body, fixed to a base frame by bolts, includes columns, intermediate beams and crossbeams. Multiple pairs of columns are symmetrically distributed and fixed to the base frame by bolts. An intermediate beam is provided in the middle of the column, and the intermediate beam is provided with a tie rod for the upper part of the furnace hearth. A crossbeam is provided at the top of each pair of columns and adjacent columns.

[0006] Furthermore, each column is provided with a column bracket in the middle, and the column bracket is fixed to the middle section beam by a bolt group.

[0007] Furthermore, the lower end of the middle section beam is connected to a tie rod hanger via a column bracket, the tie rod hanger supporting the upper tie rod of the furnace hearth, and an end face tie rod plate is provided at the end of the middle section beam. Furthermore, a side tie rod plate is provided on the tie rod beam for stabilizing the side vertical and inclined water jackets.

[0008] Furthermore, the column is provided with a crossbeam base at the middle and top, the middle crossbeam base is provided with a tie beam, and the crossbeam is welded to the top crossbeam base.

[0009] Furthermore, the tie beam is provided with a side tie plate for stabilizing the side vertical water jacket and the inclined water jacket.

[0010] Furthermore, the lower half of the column is provided with a top spring base for fixing and constraining the lateral deformation of the furnace cylinder, and the upper half of the column is provided with a tie rod ring, which is connected to the furnace top tie rod.

[0011] The beneficial effects of this utility model are as follows: The steel structure of the side-blown furnace body adopts a binding design. In terms of structural layout, multiple pairs of columns are symmetrical, connected by crossbeams and middle beams to form a stable frame. The column brackets and crossbeam bases reinforce the whole and rationally transmit force. In terms of force, the middle structure of the columns bears the weight of the furnace top, preventing water jacket deformation, extending its service life, reducing maintenance costs and the risk of production interruption. The stress point of the furnace cylinder top spring is in the column, eliminating the need for additional crossbeams, simplifying the structure and constraining furnace cylinder deformation. In terms of stability, the tie rod hanger supports the upper tie rod of the furnace cylinder, preventing vibration and bending. The tie rod plate stabilizes the water jacket, ensuring smooth process operation. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-7As shown, a steel structure device for a side-blown furnace body is fixed to a base frame 1 by bolt groups 2. It includes columns 4, middle beams 7 and crossbeams 10. Multiple pairs of columns 4 are symmetrically distributed and fixed to the base frame 1 by bolt groups 2. A middle beam 7 is provided in the middle of the column 4. The middle beam 7 is provided with a tie rod 15 for the upper part of the furnace hearth. A crossbeam 10 is provided at the top of each pair of columns 4 and the adjacent columns 4, forming a stable frame as a whole.

[0022] Specifically, each column 4 is equipped with a column bracket 6 in the middle. The column bracket 6 is fixed to the middle section beam 7 by bolt group 2. The middle section beam 7 and the column bracket 6 bear the weight of the furnace top, effectively preventing the weight of the furnace top from acting directly on the water jacket and causing the water jacket to deform.

[0023] Specifically, the lower end of the middle section beam 7 is connected to a tie rod hanger 11 via a column bracket. The tie rod hanger 11 supports the upper tie rod 15 of the furnace hearth, providing support and stability. The end of the middle section beam 7 is provided with an end face tie rod plate 13 to stabilize the end face vertical water jacket and inclined water jacket.

[0024] Specifically, the column 4 is provided with a crossbeam base 9 in the middle and at the top. The middle crossbeam base 9 is provided with a tie rod beam 12. The tie rod beam 12 is provided with a side tie rod plate 14 for stabilizing the side water jacket and the inclined water jacket. The top crossbeam base 9 is welded with a crossbeam 10.

[0025] Specifically, the lower half of the column 4 is provided with a top spring base 5 for fixing and restraining the lateral deformation of the furnace cylinder. The force points of the top spring are all on the column 4. The upper half of the column 4 is provided with a tie rod ring 8, which is connected to the furnace top tie rod to restrain the lateral deformation of the furnace top.

[0026] In practical application, the base frame 1 must first be precisely positioned to ensure its horizontal stability. Then, the furnace body steel structure device 3 is reliably connected to it using bolt group 2, and the bolts are tightened. When installing the columns 4, the spacing is determined according to the furnace shell size and they are installed symmetrically. The verticality is strictly controlled with the help of professional tools. The crossbeam base 9 is welded to the top of the column 4 to ensure the welding quality. Then, the crossbeam 10 is connected to build the top frame. The entire furnace body steel structure device 3 adopts a bundled furnace body steel structure design to precisely control the deformation of the furnace.

[0027] When the furnace top is subjected to vibration and has a tendency to shift laterally, the furnace top tie rod transmits the displacement force to the tie rod ring 8. The tie rod ring 8 distributes the force to multiple pairs of columns 4, using the vertical rigidity of the columns 4 to resist horizontal deformation and convert local impact into strain energy of the overall frame.

[0028] When the furnace hearth expands due to heat, the upper tie rod 15 of the furnace hearth suppresses its lateral deformation through axial tension. At the same time, since the upper tie rod of the furnace hearth is prone to vibration and bending, the tie rod hanger 11 is added to provide support force. The amplitude is limited by rigid support, and the spring base 5 is tightened to combine the flexible constraint with the rigid column 4. When the furnace hearth expands due to heat, it compresses the spring, and the spring further generates a counter-pushing force to continuously counteract the expansion.

[0029] The column bracket 6 and the middle beam 7 in the middle of column 4 bear the weight of the furnace top, effectively preventing the weight of the furnace top from acting directly on the water jacket and causing the water jacket to deform. Furthermore, combined with the end face tie plate 13 and the side tie plate 14, the end face vertical water jacket and the inclined water jacket and the side vertical water jacket and the inclined water jacket are stabilized respectively.
