Description

{Rotating Runner of Furnace}

The embodiment relates to a rotatable platoon, and more particularly relates to a rotatable platoon which rotates a platoon when repairing a platoon of a blast furnace, and uses all the outlets of the blast furnace.

A commonly known blast furnace operation involves charging iron ore and coke from the upper part of the blast furnace and then introducing hot air from the lower part of the hot wind furnace to melt and reduce the iron ore to produce waste. The exhaust gas generated in the blast furnace is exhausted through the outlet port after the outlet port formed on the side of the blast furnace is exhausted as the open air. At this time, the molten metal flows in a state in which the slag is gathered on the upper side and the molten iron is gathered on the lower side by the difference in specific gravity.

These chartered vessels are fed into the mixed car (TCL), which is a moving vehicle of the chartered ship, and are transported through the steelmaking process.

The melted material discharged from the blast furnace passes through the coating of the refractory material. However, when the blast furnace is over 250,000 tons in the case of the large blast furnace, the coating refractory is weakened due to the melt of 1500 degrees or more and the wear is progressed. .

There are multiple outlets in the blast furnace, and there is one high tang for each outpost, and the use of the outlets is prohibited during the inflow and re-maintenance period of two weeks. . Therefore, unlike the usual operation with four outlets, the number of outgoing outlets is narrowed down to three.

As the final goal in the outbound operation is to reduce the number of tapping taps and increase the time of departure, the use of three outlets will not allow the two outlets to be used during the outbound work such as repair work and shutdown failure This results in instability of the outgoing port due to continuous outgoing.

Due to these problems, we are currently in a hurry to shorten the repair period of the HUJI-DATUDO to the utmost, and can not assure that the DATUDO has been completely repaired as much as the inflow maintenance period, which is far from the standard repair time.

The embodiment provides a rotatable platoon that can utilize all the outlets evenly through rotation of the platoon.

The problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned here can be understood by those skilled in the art from the following description.

An embodiment of the present invention relates to a furnace for melting a charge; A plurality of outlets for discharging the melts to be melted in the blast furnace; And a plurality of hot blast ducts through which the molten material discharged from the outlet is flowed, wherein the hot blast duct is provided to rotate along the outer circumferential surface of the blast furnace.

And at least one guide portion for guiding the rotation of the superheating degree.

The guide portion may protrude along the blast furnace or the ground, and the grooved portion is provided with a groove into which the guide portion is inserted, and the guide portion is inserted into the groove portion and rotated.

At least one roller may be provided inside the groove.

And the at least one driving unit may be provided on the lower surface.

The blast furnace and the hot blast furnace are provided with a position sensing unit, and the hot blast furnace coincides with the outlet of the hot blast furnace when the hot blast furnace rotates.

Wherein the guide portion is formed in a protruding structure on a lower surface of the hot water tank, a first guide groove portion for receiving the guide portion is formed on the ground, and the first guide groove portion is formed in a position where the hot water tank and the outflow port match And a second guide groove portion for moving the hot water toward the blast furnace can be formed.

An entry guide portion may be formed at a connection portion between the first guide groove portion and the second guide groove portion.

Yet another embodiment of the present invention is a furnace for melting a charge; A plurality of outlets for discharging the melts to be melted in the blast furnace; And a plurality of super-ducts through which the molten material discharged from the outlet is flowed, wherein the super-duct is provided to rotate along an outer peripheral surface of the blast furnace, and the super-duct degree is larger than the number of the outlets .

According to the embodiment, it is possible to use the output port without a dormant outlet through the rotation of the large ditch.

In addition, there is an effect of stabilizing the tapping period, high-efficiency operation, reducing the work load and increasing the balance of the outgoing line through continuous movement of the hot water.

In addition, since the melted blast furnace can be discharged in a balanced manner through the use of the transmission line, it is possible to overcome the defects of the present invention by self-reliance triple outlet by using four outlets when the stability of blast furnace yellow is stable and when it is defective.

The various and advantageous advantages and effects of the present invention are not limited to the above description, and can be more easily understood in the course of describing a specific embodiment of the present invention.
