Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to continuous refining equipment, which is capable of coping with continuous steel extraction during refining, and which can utilize space effectively.

In order to produce high-grade steel from molten steel that is continuously tapped from a melting furnace, it is necessary to put the molten steel into a refining furnace and refine it.

During this refining, one refining furnace cannot handle continuous steel tapping, and multiple refining furnaces are required.

Conventionally, the so-called badge method was used, in which the ladle received steel and when it was full, the tapping was stopped and another ladle was set. Each smelting furnace required various equipment and required a large amount of space.

The present invention relates to continuous refining equipment made in view of the above circumstances, and includes a movable heating mechanism connected to a power source, and a steel receiving gutter that is heated by the heating mechanism and directed toward the gutter of the melting furnace. It is characterized by consisting of a plurality of refining furnaces, and a rotating gutter that supplies molten steel between the steel receiving gutter of these refining furnaces and the gutter of the melting furnace.

Embodiments of the present invention will be described based on the drawings.

At the bottom of the tip of the gutter 2 of the melting furnace 1, a rotating gutter 3 supported by a rotating table 4 and movable up and down by a cylinder 5 is installed. ) 6 are arranged side by side so that the steel receiving gutter 7 faces the swirling gutter 3 so that molten steel can be supplied from the swirling gutter 3 to each refining furnace 6. A rail 8 is laid along the rail 8, and a transformer 9 is installed on the anti-refining furnace 6 side of the rail 8, and a self-propelled arc heating mechanism support trolley 10 is placed on the rail 8. A lifting device 12 for lifting and lowering the electrode 11 of the refining furnace 6 is provided, and a cable 13 for supplying power to the electrode 11 and the transformer 9 are connected via a flexible cable 14.

First, the electrode 11 of an arbitrary refining furnace 6 (in the center in the drawing) and the transformer 9 are connected by cables 13 and 14, and the tip of the swing gutter 3 is connected to the lower side by the cylinder 5 located above the steel receiving gutter 7. tilt it to

Then, the molten steel from the melting furnace 1 passes through the gutter 2 and reaches the swirling gutter 3, from which it is supplied to the refining furnace 6 via the steel receiving gutter 7.

In this way, molten steel is supplied from the melting furnace 1 to the smelting furnace 6, and when the smelting furnace 6 is full, the connection between the transformer 9 and the electrodes 11 is cut off, and the arc heating mechanism support cart 10 is moved to the next smelting furnace 6 and set there. 9 and the electrode 11, and
On the other hand, actuate the cylinder 5 to direct the tip of the swing gutter 3 upward to store the molten steel from the melting furnace 1 in the swing gutter 3, and in this state, rotate the swing gutter 3 to transfer it to the receiving gutter 7 of the next refining furnace 6. After that, the cylinder 5 tilts the turning gutter 3 downward to supply molten steel to the refining furnace 6.

In this way, molten steel is continuously supplied from the melting furnace 1 to the refining furnace 6.

Note that the present invention is not limited to the above-mentioned embodiments, but includes, for example, arranging the refining furnace in an arc shape, using arc-shaped rails accordingly, and rotating and tilting the swing gutter and arc heating mechanism. It is optional to program the movement of the support cart, and it goes without saying that various other changes may be made without departing from the gist of the invention.

As described above, according to the continuous refining equipment of the present invention, molten steel from the melting furnace can be continuously refined and steel can be produced continuously, and the refining equipment itself can be simplified and space can be used effectively. It has excellent effects such as:
