Description

Technical Field

[0001] The present invention belongs to the field of pyrometallurgical furnace equipment, and specifically relates to a side-blown furnace body steel structure device Background Art

[0002] Traditional side-blown furnaces have complex steel structures, with numerous intertwined components. This increases the difficulty and cost of manufacturing and installation, and complicates subsequent maintenance. Transverse deformation of the original hearth was controlled by a single jacking beam, resulting in an unsophisticated structure and poor control. The illogical layout of the operating space also restricted operator mobility, impacting daily operations and equipment maintenance efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a side-blown furnace body steel structure device, aiming to solve the problems of the furnace body steel structure being not streamlined and the control effect being poor in the above-mentioned background technology.

[0004] In order to achieve the above object, the technical solution of the present invention is: A side-blown furnace body steel structure device is fixed to a base frame by a bolt group, comprising columns, middle beams and cross beams. Multiple pairs of the columns are symmetrically distributed and fixed to the base frame by bolt groups. A middle beam is provided in the middle of the columns, and the middle beam is provided with an upper pull rod of the furnace cylinder. Cross beams are provided on the tops of each pair of columns and adjacent columns.

[0005] Furthermore, a column corbel is provided in the middle of each column, and the column corbel is fixed to the middle beam through a bolt group.

[0006] Furthermore, the lower end of the middle section beam is connected to a tie rod hanger through a column bracket, the tie rod hanger supports the upper tie rod of the furnace, and the end of the middle section beam is provided with an end tie rod plate. Furthermore, the tie rod beam is provided with a side tie rod plate for stabilizing the side vertical water jacket and the inclined water jacket.

[0007] Furthermore, the middle and top of the column are both provided with beam bases, the middle beam base is provided with a pull rod beam, and the beam is welded to the top beam base.

[0008] Furthermore, the tie rod beam is provided with a side tie rod plate for stabilizing the side vertical water jacket and the inclined water jacket.

[0009] Furthermore, the lower half of the column is provided with a tightening spring base for fixing and restraining the lateral deformation of the furnace cylinder, and the upper half of the column is provided with a pull rod ring, which is connected to the furnace top pull rod.

[0010] The beneficial effects of this invention are as follows: the side-blown furnace body steel structure adopts a bundled design. The structural layout features multiple pairs of symmetrical columns, connected by crossbeams and mid-section beams to form a stable frame. The column brackets and crossbeam bases reinforce the overall structure and effectively transmit force. Regarding load bearing, the central structure of the columns bears the weight of the furnace roof, preventing deformation of the water jacket, extending its lifespan, reducing maintenance costs and the risk of production interruptions. The force applied to the furnace cylinder top spring is located on the columns, eliminating the need for additional crossbeams, simplifying the structure and limiting furnace cylinder deformation. Regarding stability, the tie rod hanger supports the upper tie rod of the furnace cylinder to prevent vibration and bending, and the tie rod plate stabilizes the water jacket, ensuring a smooth process.

DETAILED DESCRIPTION

[0013] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1-7 As shown, a side-blown furnace body steel structure device is fixed to the base frame 1 by a bolt group 2, including columns 4, middle beams 7 and cross beams 10. Multiple pairs of columns 4 are symmetrically distributed and fixed to the base frame 1 by the bolt group 2. A middle beam 7 is provided in the middle of the column 4, and the middle beam 7 is provided with an upper pull rod 15 of the furnace cylinder. Each pair of columns 4 and the top of adjacent columns 4 are provided with cross beams 10, forming a stable frame as a whole.

[0015] Specifically, a column corbel 6 is provided in the middle of each column 4, and the column corbel 6 is fixed to the middle beam 7 by a bolt group 2. The middle beam 7 and the column corbel 6 bear the gravity of the furnace top, effectively preventing the gravity of the furnace top from directly acting on the water jacket, causing deformation of the water jacket.

[0016] Specifically, the lower end of the middle section beam 7 is connected to a tie rod hanger 11 through a column corbel. The tie rod hanger 11 lifts the upper tie rod 15 of the furnace to provide support and stability. The end of the middle section beam 7 is provided with an end tie rod plate 13 to stabilize the end vertical water jacket and the inclined water jacket.

[0017] Specifically, a crossbeam base 9 is provided in the middle and top of the column 4, a tie rod beam 12 is provided in the middle crossbeam base 9, a side tie rod plate 14 is provided on the tie rod beam 12 for stabilizing the side vertical water jacket and the inclined water jacket, and a crossbeam 10 is welded to the top crossbeam base 9.

[0018] Specifically, the lower half of the column 4 is provided with a tensioning spring base 5 for fixing and restraining the lateral deformation of the furnace cylinder. The force points of the tensioning spring are all on the column 4. The upper half of the column 4 is provided with a pull rod ring 8, which is connected to the furnace top pull rod. The pull rod ring 8 is connected to the furnace top pull rod to restrain the lateral deformation of the furnace top.

[0019] When using this device, the first step is to precisely position the base frame 1 to ensure horizontal stability. The furnace steel structure 3 is then securely connected to it using the bolt assembly 2 and tightened. When installing the columns 4, the spacing is determined based on the size of the furnace shell and they are installed symmetrically. Verticality is strictly controlled using specialized tools. A crossbeam base 9 is welded to the top of the columns 4 to ensure weld quality. Crossbeams 10 are then connected to form the top frame. The entire furnace steel structure 3 utilizes a bundled steel structure design to precisely control furnace shell deformation.

[0020] When the furnace top is vibrated and has a tendency to shift laterally, the furnace top tie rod transmits the displacement force to the tie rod ring 8, and the tie rod ring 8 disperses 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 overall frame strain energy.

[0021] When the furnace cylinder expands due to heat, the upper pull rod 15 of the furnace cylinder suppresses its lateral deformation through axial tension. At the same time, because the upper pull rod of the furnace cylinder is easily bent by vibration, the pull rod hanger 11 is added to provide supporting force, and the amplitude is limited by rigid support. At the same time, the spring base 5 is tightened to combine the flexible constraint with the rigid column 4. When the furnace cylinder expands due to heat, the spring is compressed, and the spring further generates a reverse thrust force to continuously offset the expansion.

[0022] The column corbel 6 and the middle beam 7 in the middle of the column 4 bear the gravity of the furnace top, effectively preventing the gravity of the furnace top from directly acting on the water jacket, causing the water jacket to deform. Further combined with the end tie rod plate 13 and the side tie rod plate 14, the end vertical water jacket and the inclined water jacket and the side vertical water jacket and the inclined water jacket are stabilized respectively.
