Abstract
The utility model provides a molten steel export pushing off slag stopper of steel-making furnace, includes pushing off slag stopper body, outside parcel has the iron bar of the outer refractory castable of iron plate, pushing off slag stopper body and iron bar looks fixed connection as an organic whole, pushing off slag stopper body be roughly the back taper, the upper end and the lower tip of iron bar all protrusion in pushing off slag stopper body, the surface of pushing off slag stopper body be equipped with at least one vertical inside sunken tapping basin, pushing off slag stopper body form by iron grain and the mixture of cock body refractory castable, iron grain distribute in cock body refractory castable evenly. Because the iron particles are uniformly distributed in the refractory castable of the plug body, the utility model can not generate the phenomenon of deflection when in use.
Description
Technical field
The utility model relates to the floating plug in a kind of steel melting furnace exit.
Background technology
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.Therefore Chinese patent 00241086.9 discloses a kind of floating plug, 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 central axis that departs from the deviation of gravity center iron staff that causes whole floating plug of iron block position when this floating plug is understood owing to making, pushing off the slag deleterious during use.
Summary of the invention
The purpose of this utility model is to provide a kind of molten steel outlet floating plug of steel melting furnace, makes that the proportion of floating plug body is even.
The technical solution of the utility model is: a kind of molten steel outlet floating plug of steel melting furnace, comprise the floating plug body, external packets is wrapped with the iron staff of the outer refractory castable of iron block, described floating plug body and iron staff are fixedly connected and are one, described floating plug body is back taper roughly, the upper end of described iron staff and bottom all protrude from the floating plug body, the outside surface of described floating plug body is provided with at least one tapping tank that caves inward longitudinally, described floating plug body is mixed by abrasive grit and cock body refractory castable, and described abrasive grit is evenly distributed in the cock body refractory castable.
The utility model compared with prior art has following advantage:
Because abrasive grit is evenly distributed in the cock body refractory castable, therefore both guaranteed that the proportion of floating plug body was bigger, guaranteed that again the uniform proportion of having of floating plug body distributes the phenomenon of deflection when the utility model can not use.
Description of drawings
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, abrasive grit; 3, cock body refractory castable; 4, iron staff; 5, tapping tank; 6, floating plug body;
Embodiment
Referring to accompanying drawing 1 to accompanying drawing 3, a kind of molten steel outlet floating plug of steel melting furnace, comprise floating plug body 6, external packets is wrapped with the iron staff 4 of the outer refractory castable 3 of iron block, described floating plug body 6 is fixedly connected with iron staff 4 and is one, described floating plug body 6 is back taper roughly, the upper end of described iron staff 4 and bottom all protrude from floating plug body 6, the outside surface of described floating plug body 6 is provided with at least one tapping tank 5 that caves inward longitudinally, described floating plug body 6 is mixed by abrasive grit 2 and cock body refractory castable 3, and described abrasive grit 2 is evenly distributed in the cock body refractory castable 3.
