Description

[0001]
This application claims priority from US Provisional Application No. 60/121184, filed February 23, 1999 by Knudsen et al., Which is referred to as “continuously fed electroslag refining furnace”.
[0002]
BACKGROUND OF THE INVENTION
The present invention relates to a refining apparatus and method. Specifically, the present invention relates to a consumable electrode supply apparatus and method for a refining apparatus.
[0003]
In some conventional refining equipment, an ingot is used as a source metal source to be refined. For example, in an electroslag refining apparatus, a consumable electrode may be used as a source metal source and as a part of an electric circuit used for melting an ingot during electroslag refining. These electroslag refining apparatus and methods may require a great deal of preparation for the placement and use of consumable electrodes. Typically, the consumable electrode was attached to a vertical motion control device (e.g., a stub secured to the power unit) that allows mechanical movement of the consumable electrode into the electroslag refining device. Such a vertical motion control device includes a welded portion between the consumable electrode and the stub of the vertical motion control device, a screw or bolt type connection between the consumable electrode and the stub of the vertical motion control device, a consumable electrode and the vertical motion control. There are clamps between the stubs of the device and other vertical motion control structures between the consumable electrode and the stub of the vertical motion control device. Such vertical motion control devices also provide electrical contact between the consumable electrode and the power source.
[0004]
The electroslag refining of the consumable electrode and the movement of the consumable electrode are typically stopped before reaching the consumable electrode end opposite the consumable electrode end cooperating with the electroslag refining device. Such movement stop is required to prepare a new consumable electrode for refining in an electroslag refining device, and to connect the new consumable electrode to a vertical motion control device to replace the existing consumable electrode. Stopping movement is also required to prevent damage to the vertical motion control device components, for example when the vertical motion control device components are too close to the melt in the electroslag refining device. The stoppage of movement also serves to avoid contamination of the electroslag refined molten metal, for example, by contaminants originating from the vertical motion control device. Such movement stoppage is not desirable, even if necessary with conventional electroslag refining equipment. This is because the operation time of the electroslag refining apparatus may be reduced, the yield of electroslag refining may be reduced, the stop time of the electroslag refining apparatus may be increased, and contamination of the electroslag refining apparatus may be increased.
[0005]
Electroslag refining (ESR) equipment and methods are known in the art. For example, an electroslag refining apparatus, method and related features are disclosed in US Pat. No. 5,160,532 to Benz et al., Which also discloses a cold induction guide (CIG) type transfer apparatus. Additional electroslag refining apparatus, methods and related features are all disclosed in the following US patents assigned to the assignee of the present application, the disclosure of which is hereby incorporated by reference: Benz U.S. Pat. No. 5,160,532, Benz et al., 5310165, Benz et al., 5,325,906, Sawyer et al., 5,348,566, Sawyer et al., 5,366,206, Benz et al., 5,472,177, Carter, Jr. No. 5480097, Carter, Jr. et al. No. 5649999, Carter, Jr. et al. No. 5649993, Benz et al. No. 5,683,653, Carter, Jr. et al. No. 5,769,151, Benz et al., 5,809,057, and Knudsen et al., 5,811,0066.
[0006]
Furthermore, the difficulty in producing castings (eg, large diameter castings having a diameter of more than about 18 inches) may increase when moving and connecting and replacing consumable electrodes. . In large diameter ingot casting methods, it is common to use a plurality of consumable electrodes connected to a vertical motion control device. Inhomogeneous regions can occur in the castings obtained with any consumable electrode connection operation. Such a heterogeneous region is a variation of a small amount of components in the consumable electrode, a contaminant that may be mixed in the electroslag refining melt during the movement stop and consumable electrode connection work, a difference in electroslag refining conditions before and after the movement stop, May be attributed to other electroslag refining variables. Of course, such inhomogeneous regions are not desirable in the resulting castings and products made from such castings, including but not limited to turbine components.
[0007]
Thus, there is a need to provide a consumable electrode for an electroslag refining apparatus and method that avoids movement stops during electroslag refining. There is a further need to provide an electroslag refining apparatus and method that avoids yield loss, contamination during electroslag refining, and damage to the vertical motion control device. Further, there is a need to provide an electroslag refining apparatus and method that does not generate a heterogeneous region when the consumable electrode is stopped and connected.

The posture can be vertical as shown in FIG. The side supply device 14 delivers the consumable electrode to the refining supply device 15. The refining supply device 15 can move the consumable electrode 11 in a second direction (arrow 150) that is substantially orthogonal to the first direction 140. The consumable electrode supply device 10 also includes a coupling device 16 for coupling the consumable electrodes in a manner sufficient to avoid a stop during refining.
[0017]
The refining supply device 15 includes a device that can move the consumable electrode 11 into the refining device 20 through the connecting device 16. The smelting and supplying apparatus 15 may include a descent power device that can move and descend while controlling the consumable electrode 11. Movement and descent under control can be controlled by the melting rate in the refining device 20. For example, controlled descent may include gradual movement and descent. The refining supply device 15 that moves the consumable electrode 11 into the refining device may include a power device that can impart appropriate lowering and control to the consumable electrode. The smelting / feeding device may be composed of a catapillar device, a tread device, a belt device, a chain device, other similar power devices, or a combination thereof capable of moving the consumable electrode under control in the smelting device.

[0020]
The connecting device 16 for connecting the consumable electrodes does not need to generate a strong connecting portion. The term “strong” as used herein means that the connecting portion carries a large amount of current and supports a large weight. The connecting portion between the consumable electrodes only needs to support the weight of the consumable electrode, and is not intended to pass an electric current for the electroslag refining method. Although the following description relates to a coupling device 16 comprising a weld coupling device, this description is merely for illustrative purposes.

2 and 3 show the characteristics of the electroslag refining device 20 to which the consumable electrode 11 is supplied by the consumable metal supply device 10 according to the present invention. The electroslag refining apparatus 20 refines the consumable electrode 11 to generate a clean refined metal melt 446 (hereinafter referred to as “clean metal”). The clean metal 46 is accommodated and held in a low-temperature hearth structure 40 attached below the electroslag refining apparatus 20. The clean metal 46 is discharged from the cold hearth structure 40 through a cold finger orifice structure 80 disposed below the cold hearth structure 40.
[0024]
The electroslag refining apparatus 20 is configured such that the metal electroslag refining rate and the refining metal delivery rate to the low temperature hearth structure 40 are the molten metal 46 from the low temperature hearth structure 40 through the orifice 81 of the cold finger orifice structure 80. If the discharge rate is approximated, the supply of the clean metal 46 is substantially steady. Therefore, electroslag refining using the consumable metal supply device 10 according to the present invention can be operated continuously for a long period of time and can process a large amount of metal.
[0025]
The electroslag refining apparatus 20 has a passage 201 disposed at the upper part of the electroslag refining apparatus 20. The passage 201 is dimensioned to allow the refining consumable electrode 11 to pass therethrough. When refining only consumable electrodes of a single size with a refining apparatus, the passage 201 may be formed to have a certain size, or alternatively, the passage may allow passage of consumable electrodes of various sizes. The dimensions may be variable. The passage 210 forms a sealing structure with the consumable electrode sufficient to prevent contamination from entering the refining apparatus.
[0026]
The electroslag refining apparatus 20 includes an electroslag refining structure 30. The electroslag refining structure 30 may include a molten metal reservoir 32 that is cooled by a suitable coolant such as water, although not limited thereto. Molten reservoir 32 contains molten slag 34, with excess slag 34 shown as solid slag particles 36. The composition of the slag varies depending on the metal to be treated. As will be described later, the slag skull 75 can be formed on the inner surface of the inner wall 82 of the molten metal reservoir 32 by the cooling action of the coolant flowing outside the inner wall 82.
[0027]
A low-temperature hearth structure 40 is attached below the electroslag refining structure 30. The low temperature hearth structure 40 includes a hearth 42 cooled with a suitable coolant such as water. The hearth 42 contains a solidified refining metal skull 44 and a refining liquid metal 46. The molten metal reservoir 32 may be formed integrally with the hearth 42. Alternatively, the molten metal reservoir 32 and the hearth 42 may be formed as separate units and connected to form the electroslag refining apparatus 20.
[0028]
The cold finger orifice structure 80 is provided with a bottom orifice 81 of the electroslag refining apparatus 20, which will be described with reference to FIGS. The clean metal 46 refined by the electroslag refining apparatus 20 and substantially free of oxides, sulfides and other impurities flows out of the orifice 81 of the cold finger orifice structure 80 across the electroslag refining apparatus 20. .
[0029]
The power supply structure 70 supplies a refining current to the electroslag refining device 20 and the consumable electrode 11. The power supply structure 70 may include a power supply control mechanism 74. The electric conductor 76 can transmit current to the consumable electrode 11. If the conductor 78 is connected to the molten metal reservoir 32, the circuit of the power supply structure 70 of the electroslag refining device 20 is completed.
[0030]
2 and 3 are detailed partial cross-sectional views of the electroslag refining structure 30 and the low-temperature hearth structure 40. The electroslag refining structure 30 defines the upper part of the molten metal reservoir 32 and has a low-temperature hearth structure. Object 40 defines a lower portion 42 of molten metal reservoir 32. In general, the molten metal reservoir 32 is a double-walled molten metal reservoir having an inner wall 82 and an outer wall 84. Although not particularly limited, a coolant 86 such as water is supplied between the inner wall 82 and the outer wall 84. The coolant 86 may flow from a source through a normal inlet and outlet (not shown) to a flow path defined between the inner wall 82 and the outer wall 84. The cooling water 86 for cooling the wall 82 of the low-temperature hearth structure 40 cools the electroslag refining apparatus 30 and the low-temperature hearth structure 40 to form a skull 44 on the inner surface of the low-temperature hearth structure 40. The coolant 86 is not essential for operation of the electroslag refining device 20, the clean metal nucleation casting device 3 or the electroslag refining structure 30. Cooling reliably prevents the liquid metal 46 from contacting and attacking the inner wall 82. Otherwise, the wall 82 may dissolve somewhat and contaminate the liquid metal 46. The cryogenic hearth structure 40 also includes an outer wall 88, which may include flanged tubular portions 90 and 92. At the bottom of FIG. 2, two flanged tubular portions 90 and 92 are shown.
.
[0031]
The cryogenic hearth structure 40 includes a cold finger orifice structure 80 shown in detail in FIGS. The cold finger orifice structure 80 is shown in FIG. 3 with respect to a stream 56 of liquid metal 46 exiting the cold hearth structure 40 through the cold hearth structure 40 and the cold finger orifice structure 80. Cold finger orifice structure 80 includes an orifice 81 that cooperates with solid metal skull 44 and liquid metal 46 and causes process molten metal 46 to flow out as stream 56. The cold finger orifice structure 80 is connected to the low temperature hearth structure 40 and the low temperature hearth structure 30. Thus, the low temperature hearth structure 40 generally allows a processing alloy free of impurities to contact the walls of the low temperature hearth structure 40 to form the skulls 44 and 83.
[0032]
Thus, the skulls 44 and 83 function as a container for the molten metal 46. Further, the thickness of the skull 83 (FIG. 3) formed in the cold finger orifice structure 80 can be controlled, and is generally formed to be thinner than the skull 44. The thick skull 44 contacts the low temperature hearth structure 40, the thin skull 83 contacts the cold finger orifice structure 80, and the skull 44 and the skull 83 contact each other to form a substantially continuous skull.
[0033]
The amount of heating and cooling supplied to the skulls 44 and 83 and the liquid metal 46 via the cold finger orifice structure 80 can be controlled by adjusting the amount of liquid metal 46 that passes through the orifice 81 as a flow 56. Control of heating or cooling is performed by adjusting the amount of current and coolant flowing through the induction coil 85 connected to the cold finger orifice structure 80. The operation of the induction coil 85 to control the heating or cooling of the cold finger orifice structure 80 is described in the above-mentioned US patent. By controlling the heating or cooling, the thickness of the skulls 44 and 83 can be increased or decreased, and the opening / closing of the orifice 81 or the amount of the flow 56 passing through the orifice 81 can be increased or decreased. By increasing or decreasing the thickness of the skulls 44 and 83, the flow 56 can be regulated by adjusting the amount of liquid metal 46 that flows into the orifice 81 through the cold finger orifice structure 80. By controlling the cooling water, heating current and power to the induction heating coil 85 to maintain the orifice 81 at a predetermined passage size while controlling the thickness of the skulls 44 and 83, the flow of the flow 56 is kept in the desired balance. be able to.
[0034]
In carrying out the method of using the consumable electrode supply device according to the present invention together with the electroslag refining device 20, the side supply device 14 moves the consumable electrode 11 ("supply consumable electrode"). The supply consumable electrode 11 is moved to a position substantially above the previously supplied consumable electrode 11 located in the refining supply device 15. For example, the consumable electrode 11 supplied last time in the refining supply device 15 may already be arranged in the electroslag refining device 20 or may be connected to another consumable electrode in the electroslag refining device 20. Sometimes. The lateral supply device 14 moves and aligns the supply consumable electrode 11 above the previously supplied consumable electrode located immediately before in the consumable electrode supply device 10. The consumable electrode supplied last time may be a consumable electrode being melted or a consumable electrode to be melted next. The supply consumable electrode 11 can be moved into the consumable electrode supply device 10 when a predetermined amount of the consumable electrode 11 supplied last time is fed or melted into the electroslag refining device 20.
[0035]
When the supply consumable electrode 11 is arranged in the refining supply device 15, the refining supply device 15 moves the consumable electrode in the direction of the arrow 150 toward the connecting device 16 and the refining device 20. The movement of the supply consumable electrode may consist of a gradual movement and lowering. The operation of moving and lowering the supply consumable electrode under control by the refining supply device 15 is sufficient to place the end of the previously supplied consumable electrode and the end of the adjacent supply consumable electrode at the position of the coupling device 16. It is a thing. Next, the connecting device 16 of the consumable electrode supply device 10 can connect the consumable electrodes while abutting the consumable electrodes so that there is no gap or separation between the consumable electrodes. Furthermore, as a result of the consumable electrodes being abutted so as to avoid the stop of refining, the consumable electrode supply device can provide a substantially continuous consumable electrode for refining.
[0036]
The consumable electrode supply device 10 and its use in the refining device avoids contamination of the refined molten metal and damage of the consumable electrode transfer device, and thus does not result in a decrease in yield. In addition, since the inhomogeneous region that may arise from the refining stop and the consumable electrode replacement work is avoided by the consumable electrode supply device 10 according to the present invention, the consumable electrode supply device 10 is formed by casting a large diameter from a plurality of consumable electrodes. Make it easy to manufacture goods.
