Abstract
The utility model relates to a slag blocking plug for molten steel outlets of steel melting furnaces. The utility model is characterized in the exterior of a circular iron block [2] is coated with iron block outer refractory castable [3]; the iron block outer refractory castable [3] forms an approximately inverted cone shape; the axial line of the center of the circular iron block [2] is inserted with an iron rod [4]; the upper end and the lower end of the iron rod [4] are protruded out of the iron block outer refractory castable [3]; the outer surface of the iron block outer refractory castable [3] is provided with one longitudinally and inwards sunk molten steel outlet groove [5] at least. After most of molten steel is exhausted, the utility model is thrown to the outlet of the steel smelting furnace, a small amount of molten steel can flow down from the molten steel outlet groove, and then the molten steel is fully exhausted. The steel production rate is improved, and the slag body is blocked in the slag outlet.
Description
The utility model relates to the floating plug in a kind of steel melting furnace exit.
In the prior art, after the molten steel outlet of steel melting furnace was in most of molten steel, small part molten steel and slag body mixed, and this part molten steel is often drained as waste product with the slag body, has wasted the small part molten steel.
It is a kind of after most of molten steel has been arranged that the purpose of this utility model is to provide, and can be in the exit slag body blocked and still allows the molten steel outlet floating plug of the last effusive steel melting furnace of small part molten steel.
The technical solution of the utility model is: a kind of molten steel outlet floating plug of steel melting furnace, the external packets of annular iron block is wrapped with the outer refractory castable of iron block, the outer refractory castable of described iron block is back taper roughly, the center hub line place of described annular iron block is inserted with iron staff, the upper end of described iron staff and bottom all protrude from the outer refractory castable of iron block, and the outside surface of the outer refractory castable of described iron block is provided with at least one tapping tank that caves inward longitudinally.
The utility model compared with prior art has following advantage:
After most of molten steel is discharged, the exit that the utility model drops into steel melting furnace, block tap hole by the utility model, a spot of molten steel can also flow down along the tapping tank, so that molten steel goes out to the greatest extent, improves the tapping rate, and the slag body then can be blocked in the outlet.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 partly cuts open figure for structure of the present utility model;
Accompanying drawing 2 is a vertical view of the present utility model;
Accompanying drawing 3 is a upward view of the present utility model; Wherein:
[1], the outer refractory castable of iron staff; [2], annular iron block; [3], the outer refractory castable of iron block; [4], iron staff; [5], tapping tank;
Embodiment: referring to accompanying drawing 1 to accompanying drawing 3, a kind of molten steel outlet floating plug of steel melting furnace, the external packets of annular iron block [2] is wrapped with the outer refractory castable [3] of iron block, the outer refractory castable [3] of described iron block is back taper roughly, the center hub line place of described annular iron block [2] is inserted with iron staff [4], the upper end of described iron staff [4] and bottom all protrude from the outer refractory castable [3] of iron block, and the outside surface of the outer refractory castable [3] of described iron block is provided with at least one tapping tank [5] that caves inward longitudinally.The lower external face of described iron staff [4] is enclosed with the outer refractory castable [1] of iron staff.
Referring to accompanying drawing 2 and accompanying drawing 3, the outside surface of the outer refractory castable [3] of described iron block is provided with three equidistances tapping tank [5] that caves inward at interval.
Claims (3)
