Similarly, the word The subject is the inner region of the metallurgical furnace (100) surrounded by firebricks (108). In order to remove the molten material (118) located in the metallurgical furnace (100) single 25 towards a tap (not shown in the figure) during a bulk melting process It can be tilted more than once in a second direction around the tilt axis (122). Roof lifting elements (124) can be fitted to one end of the roof (120). Roof Lifting elements (124) chains, cables, rigid supports or roof (120) Other suitable mechanisms for support may be in the form of a roof lift. 30 The elements (124) can be attached to one or more pole arms (126) at the second end. The mast arms (126) extend horizontally from a mast support (128) and outwards. 6 It is spreading. The pole support (128) is provided by a pole upright (130). It is supported. Pole support (128) around the pole upright (130). It can rotate. Alternatively, move the roof lifting elements (124). In this way, the pole upright (130) can rotate together with the pole support (128). Another In the example, roof lifting elements (124) are used to move the roof (120) from the air 5 It can be supported. In an alternative example, the roof (120) away from the side wall (110). It is structured to swing or rise correctly. Material is placed inside. In order to load the metallurgical furnace (100), an opening (101), namely its internal volume, side To expose the roof (120) from the side wall (114) over the upper wall (110). (110) is being raised further away. 10 The roof (120) can be circular in shape. In at least one example, the roof (120) is for cooling. by using the system (121) or another suitable temperature control mechanism It is cooled by spray. A central opening (134) can be created on the roof (120). One or more electrodes (136) can be connected to the roof (120) via a central opening (134) It extends from a position above into the opening (101). The metallurgical furnace 15 (100) During its operation, it will melt the metal and thus the molten material (118) In order to provide the heat generated by an electric arc that will enable its production, electrode(s) (136) through the central opening (134) of the metallurgical furnace (100) (101) It is lowered into the inside. In one example, the roof (120) is produced inside the metallurgical furnace (100). an exhaust nozzle for removing vapors (not shown in the figures) 20 It includes. FIGURE 2 is an isometric view of the side wall (110) shown in FIGURE 1, where A section of the side wall (110) has been cut off and removed. The side wall (110) is a central part. arranged radially in the z direction (199) around the line (201). It is shown. The said center line (201) is parallel to the y direction (197) and the said 25 The subject is the centerline (201) of the radial center of the opening (101). Side wall (110) When the metallurgical furnace (100) is installed on the furnace (106), this opening (101) metal, scrap metal or other fusible materials to be melted in a metallurgical furnace (100) It provides a passage that allows entry. The side wall (110) leads to an internal cavity (204) where a spray cooling unit (208) is arranged. It has a spray cooling unit (208) during the operation of the metallurgical furnace (100). cooling system used to control the temperature of the wall (110) (121) is a part of spray cooling, which will be discussed in more detail below. group (208) concentrically within the inner cavity (204) of the side wall (110). 7 It may include one or more parts arranged. Spray cooling unit (208), a coolant such as water supplied from the cooling system (121) on the inclined side wall It is structured to pour cold water onto its surface. Coolant water or liquid. is not limited to base fluids and can be an aqueous liquid, foam or anhydrous coolant. It can be in this form. Side wall (110) on the furnace (106) of the metallurgical furnace (100) 5 When installed, the spray cooling unit (208) is placed inside the inner cavity (204). It is connected to the inlet cooling port (117) to deliver the coolant. In one example, the side wall (110) of the metallurgical furnace (100) has one or more holes (212) It can contain. Holes (212) extend through the side wall (110) and thus into the opening. (101) provides physical access. In one example, the hole (212) leads to a burner nozzle. It can be used to provide access to the openness (101). In another example, the side wall (110) includes one or more covers (216). Covers (216), slag and molten material (118) in the manner discussed above. It can be used for the purpose of removal. FIGURE 3 shows an example configuration of the side wall (110). Side wall 15 (110), A cross-section view taken along the AA section line depicted in FIGURE 2. It is shown as follows. FIGURE 4 is an enlarged partial view of the side wall (110). The side wall (110) has a top wall (300), an interior wall (304), a bottom wall (308) and an exterior wall. It includes the wall (312). The inner wall (304) of the side wall (110) also has an upper sloping wall. (380) includes a return wall (316) and a lower wall (320). Return wall (316) 20 with the lower wall (320) the upper sloping wall (380) the lower wall (308), the said upper sloping In a way that will form a leakage containment element below the wall (380). It connects. In one example, the leak containment element is a collection pool (362). The collection pool (362) is blocked by, for example, a piece of scrap steel on the inner wall (304). If the inner wall (304) of the oven 25 is damaged due to being punctured It holds the water that might flow downwards on the side. An inner surface of the inner wall (304) (303) (e.g., cold face) faces the interior cavity (204). An outer surface of the inner wall (304) (305) (e.g., the hot surface) is located opposite the inner surface (303) and inside the oven (100). It looks at the electrodes arranged in part (136). Therefore, the outside of the inner wall (304) The surface (305) faces the opening (101). As previously stated, the centerline is 30 (201) is the center of the (101) opening. The upper sloping wall (380) of the inner wall (304) extends inwards and downwards from the upper wall (300) to the first It extends at an angle (301). The first angle of the side wall (110) (301) is inside the upper wall (300). 8 It is formed between the inner surface (303) and the upper sloping wall (380) (303). A second angle (302) between the return wall (316) and an imaginary line (306) It is created. The imaginary line (306) is perpendicular to the center line (201) along the x direction (195). It extends as follows. The imaginary line (306) is also parallel to the lower wall (308). First angle (301) Greater than 90 degrees and less than approximately 145 degrees. The second angle (302) is zero 5 It is equal to or greater than a degree and, for example, ranges from zero to 45 degrees. In the example, the first angle (301) is approximately between 95 degrees and 115 degrees. Another In the example, the first angle (301) is approximately between 120 degrees and 135 degrees. An alternative In the example, the first angle (301) is 130 degrees. The second angle (302) is approximately 15 degrees in one example. between 25 degrees. Alternatively, the second angle (302) is approximately 30 degrees to 40 degrees. The second angle (302) is between degrees. The second angle can be approximately 45 degrees. In another example, the second angle (302) can be proportional to the height of the outer wall (312). For example, as the height of the outer wall (312) increases, the magnitude of the second angle (302) It can decrease. Therefore, as the height of the outer wall decreases, the second angle (302) It can grow. 15 The spray cooling unit (208) shown in FIGURE 2, with additional details in FIGURE 3. It is represented. The spray cooling unit (208) connects to a main pipe (324), to the main pipe (324) connected to a series of branch canals (328) and spray connected to the branch canals (328). It includes a row of nozzles (332). Main pipe (324), inlet cooling It is connected to the mouth (117). The main pipe (324) is generally inside the inner cavity (204), the upper 20 It is located on the wall (300) or near the upper wall (300). Branch channels (328) The branch channels (324) extend downwards from the main pipe. In one example, the branch channels (328) are connected to the main pipe. downwards in a non-vertical direction from the pipe (324) and the branch in question the far end of the channels (328) from the outer wall (312), the branch channels (328) 25 It extends. In an advantageous way, the non-vertical direction of the branch canal (328), more space to perform service operations within the internal space (204) In this example, the branch channel (328) has a large gap between it and the sloping wall (380). It maintains a constant distance to a certain extent. In the cross-sectional view in FIGURE 3. Although only one branch canal (328) is shown, the internal space of the branch canals (328) is 30 (204) around, essentially the entire cold face of the upper sloping wall (380) and at will depending on the other parts of the inner wall (304) will be supplied with coolant. It should be appreciated that it is distributed in this way. 9 Each mouthpiece (332) is connected to the branch canal (328). From the mouthpieces (332) on the upper a coolant (336) on the inner surface (303) of the inclined wall (380) Coolant (336) is sprayed through the inlet cooling port shown in FIGURE 1. This is one of the examples of the coolant that is introduced into the inner cavity (204) via (117). In a sample configuration of the side wall (110), the branch channel (328) is connected to the upper wall (300) 5 According to the first angle (301), it is arranged. To put it differently, The branch channel (328) is largely parallel to the inner surface (303) of the upper sloping wall (380). In each of the configurations revealed here, the mouthpieces (332) are located on the upper sloping wall (380) to spray the coolant (336) onto the inner surface (303). is arranged. The coolant sprayed onto the inner surface (303) is the inner 10 The coolant flows from the surface (303) to the return wall (316) and the consumed coolant flows to this return wall from its wall (316), a return wall (316) extending below the end of the wall (316) It is directed to the drain chute (340). The drain chute (340) is outside a chute wall (317). It includes a groove base (307) connecting to the wall (312). The outer wall (312) The section forms part of the drain channel (340). The drain channel (340) is 15 of the lower wall. (308) is located above and generally surrounds the return wall (316). As the coolant flows over the inner surface (303), gravity interacts with surface tension. This causes the droplets to fall from the inclined inner surface (303) and Thus, a layer of coolant flow leaving the inner surface (303) This prevents the formation of a mouthpiece closer to the lower wall (308) 20 (332) by such a coolant flow layer of sprayed coolant It allows it to reach the inner surface (303) more effectively without being hindered. It is well-known. The interior space (204) allows maintenance personnel to access the interior surface (303) from inside the side wall (110). It has a sufficiently large volume to allow access. Advantageously, side 25 Simplifying the inspection and maintenance of the wall (110) spray cooling unit (208) It provides routine maintenance for personnel through the side wall (110) and restrictive without the limited visibility offered by maintenance covers or internal It is necessary to disassemble the side wall (110) in order to inspect the components. It makes it possible to accomplish this without the need for any further action. 30 The inner surface of the return wall (316) extends beyond the lower wall (320) and into the drain chute (340) It extends. Coolant (336) returns from the inner surface (303) of the inclined wall (380). It extends to the wall (316) and into the drain channel (340). The drain channel (340), 10 It may include a channel (344) connected to the drain outlet (119) of the cooling system (121). Channel (344) carries the coolant (336) from the drain channel (340) on the side wall (110) to provide a way for the water to flow out and into the outlet (119) and thus, removal of the consumed refrigerant from the side wall (110) It can be provided. 5 A first gap (348) is defined between the lower wall (320) and the drain chute (340). The first gap (348) carries the coolant (336) located in the drain chute (340). It insulates from the wall (320). Therefore, if the lower wall (320) is punctured, the side the fluid inside the wall (110) or drain chute (340) inside the metallurgical furnace (100) It is possible for it to seep into the part and come into contact with the molten material (118) in the furnace (106). It is not. In the example shown in FIGURE 3, the lower wall (308) is towards the firebricks (108) in the interior. It includes a lower extension wall (350). FIGURE 4 shows the side wall (110) It is an enlarged partial view. FIGURE 5, a partial view of the right front of the side wall (110). This is the isometric view. To ensure it is clearly visible, see FIGURES 4 and 5. Only a subsection of the outer wall (312) is shown. As shown, the lower extension wall (350) is integrated into the lower wall (308). In another application, the lower extension wall (350) can be attached to the lower wall (308) or to the lower wall (320). A lining wall (360) is attached to the far end of the lower extension wall (350) and the bottom It extends upwards from the reclining wall (350) and away from the hearth (106). A 20 In the example, firebricks (108) are laid vertically along the side of the lining wall (360) facing the furnace. It is positioned as follows. In some examples, the lining wall (360), the hearth (106) It is flush with the back of the lining fire bricks (108). In one example, the lining wall (360) A height ranging from 6 inches to 20 inches, for example, a height ranging from 10 inches to 18 inches It has firebricks (108), from the hearth (106) to the top of the lining wall (360) 25 It is able to reach. In some applications, the lining wall (360) radially in the interior away from the inner wall (304). extending as and at least part of the upper surface (358) of the firebricks (108). It has a cover wall (365). As shown, the cover wall (365) fires. It covers a part of the upper surface (358) of the bricks (108). In some examples, the cover is 30 along the entire surface (358) of the upper (365) fire bricks (108) of the wall (365). It can extend. The lining wall (360) is advantageously constructed with firebricks (108). a barrier that leaves a distance between other parts of the wall (110) such as the lower wall (320) 11 It has an effect and thus, fire bricks (108) are transferred to the side wall (110). It helps to reduce the heat load. In some applications, the lining wall (360) and the cover wall (365) is made of steel. Lining wall (360), bottom wall (320) and bottom a leakage containment element such as a collection pool (362) between the retaining wall (350) is being created. The collection pool (362) is damaged by the structure of the inner wall (304). in case of leakage from the oven side of the inner wall (304) It retains water. Looking at FIGURE 6, at the bottom of the inner wall (304), for example at the bottom wall (320) A series of holes (323) are created. FIGURE 6 shows a partial front view of the side wall (110). Its appearance is shown here, and for the sake of keeping the image clear and understandable, the outer wall is 10 (312) only the lower section is shown. Holes (323) partially, lower wall (308) It can be limited by a series of holes (323) behind the lining wall (360). is located and covered by the said lining wall (360) and collection It is open to the pool (362). Holes (323), bottom wall (320) and lining wall (360) 15 of the seeping water that may be present in the collection pool (362) defined between them safely down the drain chute (340) and away from the inside of the oven It provides a flow path that will allow it to flow. A series of holes (323), inside They can be arranged in a circular fashion around the wall (304) at intervals relative to each other. Holes (323) can have any suitable shape such as rectangular or arc-shaped. It is possible. In this example, the holes (323) are in the form of slits. The holes (323) are suitable for any 20 It can have a certain size. In some examples, the ratio of width to height is 15:1 to... The ratio can vary between 1:5, for example, it can be 10:1. In some examples, The holes (323) can have a width ranging from 2 inches to 10 inches. Interior wall (304) any number of holes (323), e.g. 1 to 50 holes It may include. 25 FIGURE 8 shows another side wall (110) suitable for use with the oven (100) instead of the previous side wall. FIGURE 9 shows the application of a side wall (500). This is an enlarged partial view. FIGURES 9 and 10 show the image kept clear and understandable. In terms of the outer wall (512) it shows only the lower part of the side wall (500). one upper wall (502), one inner wall (504), one lower wall (508) and one outer wall (512) 30 It includes a drain channel (340) between the inner wall (504) and the outer wall (512). It is being created and surrounds an internal void (204).
