Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for supplying an additive to molten steel in a pan by using a wire feeder in a steelmaking process of an ironmaking process.

[0002]

[Prior art]

 In the steel making process of the iron making process, as a method of adding an additive to the molten steel in the ladle, a method of supplying the additive to the molten steel in the ladle using a wire feeder is generally used. At this time, if the type of additive is changed or the wire of the wire drum is used up during the addition, the steelmaking operator uses a crane to manually replace the wire drum.

[0003]

[Problems to be solved by the device]

 However, in the work of supplying the additive to the molten steel in the ladle using the wire feeder, if the type of additive is changed or the wire of the wire drum is used up during the addition, Since the operator manually uses a crane to replace the new wire drum, the additive supply work time is extended, and the load on the steelmaking operator is increased, leading to an increase in personnel. was there .

An object of the present invention is to provide an automatic wire switching device for a wire feeder that solves the above problems.

[0005]

[Means for Solving the Problems]

 The present invention is an automatic wire switching device for a wire feeder that supplies a wire-shaped additive wound around a wire drum to molten steel in a container in a steelmaking process, and is a device perpendicular to the wire feeding direction of the wire feeder. A movable carriage, and a wire drum rotation driving device arranged in a direction parallel to the wire feeding direction so that a plurality of wire drums are coaxially arranged on the carriage. It is an automatic wire switching device for a wire feeder, which is characterized by comprising wire pipe guides corresponding to the wire drums mounted on the device.

[0006]

[Action]

 According to the present invention, several kinds of wire drums are prepared in advance on the dolly in the process of supplying the additive to the molten steel in the ladle or other container using the wire feeder, and the dolly is moved to a predetermined position. Set the required drum at the position and operate the wire by rotating the wire drum forward and backward to easily switch the type of additive, or move the dolly when the wire is used up and move the same type. Supply can be easily continued by switching to the wire.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing a configuration of an embodiment of the present invention, and FIG. 2 is a plan view taken along line AA. Reference numeral 1 is a container such as a ladle containing molten steel to be treated, 2 is molten steel to be treated, 3 is a lid of the container, 4 is a pedestal that supports a wire feeder 8 and a lifting device 5 of the lid 3 of the container. Is. 6 is a guide for the wire 7 to be put into the molten steel, and 8 is a wire feeder, which is constituted by pinch rolls and leveling rolls. The wire 7 passes through the wrapper guide 8a and the wire guide 6 of the wire feeder 8. Reference numeral 9 denotes a trolley for loading a wire drum 11 on which wires are wound, and a plurality of wire drums can be loaded on the trolley. In FIG. 2, as an example, three wire drums 11a to 11c are loaded. . 10 is a rail of the truck, and 12 is a device for driving the wire drum 11 to rotate forward and backward. Reference numeral 13 is a pipe guide for guiding the end of the wire, 14 is a wheel of the truck, and 15 is a drive motor of the truck.

The wire 7 is supplied from a wire drum 11 and passed through a wire feeder 8 and put into the molten steel 2 to be processed. First, while setting the container 1 containing the molten steel 2 to be processed in the pit, the operator sets the wire drum 11 on the carriage 9 using an overhead crane (not shown) and the like. Thread the end of the wire 7 of the drum through the pipe guide 13.

Next, in order to set the wire 7 on the wire feeder 8, first, the carriage 9 is moved by the drive motor 15, and the pipe guide 13 of the wire drum 11 of a predetermined brand comes to a position in front of the wire feeder 8. When the wire drum rotation drive device 12 is rotated forward and the wire 7 is sent out in the direction of the arrow in FIG. 1, the tip of the wire 7 is caught in the wire feeder 8 via the trumpet guide 8a, and the wire guide 8 It is thrown into the steel through No. 6.

Next, when changing the type of the wire 7, the rotation driving device 12 of the wire drum is reversely rotated, and the wire 7 is pulled out and stopped when the tip of the wire 7 comes into contact with the pipe guide 13. Pull out the wire 7. For this control, a photoelectric sensor may be used, or the number of rotations of the drive rotating device 12 of the wire drum 11 may be counted.

After that, the carriage 9 is moved so that the pipe guide 13 of the wire drum 11 of another brand comes to the front of the wire feeder 8, and the wire 7 is bitten through the pipe guide 13 from the wrapper guide 8 a of the wire feeder 8. No, repeat the same operation. It is possible to control the above series of operations with the control device.

[0012]

[Effect of device]

 As explained above, in the steelmaking process of the steelmaking process, in a device that uses a wire feeder to supply additives to molten steel in a pan, several types of wire drums are prepared in advance on a trolley, and the trolley is movable. Set to the desired position and rotate the wire drum forward and backward to operate the wire to easily switch the type of additive, or when the wire is used up, switch to the same type of wire for easy supply. It is possible to continue, and it is possible to save work time and save labor.
