Abstract
The utility model relates to a guide rod which is provided with an element rest or a groove, the guide rod includes a reinforced bar and a fire-resisting material protective layer; the fire-resisting material protective layer is installed on the external surface of the reinforced bar, the utility model is characterized in that the surface of the fire-resisting material protective layer is equipped with an element rest or a groove. The product can reach ideal slag-blocking effect in the condition that the molten steel buoyancy is big and the steel slag specific gravity is large, the product can effectively reduce the buoyancy of slag bolt, the specific gravity of the slag bolt is enhanced, the weight of slag bolt is reduced, thereby reaching the fine slag-blocking effect without enhancing slag bolt specific gravity.
Description
Technical field: the utility model relates to removes slag, the band convex tendon that improves molten steel purity or the slag rod guiding rod of groove in a kind of convertor steelmaking process.
Background technology: the tail rod outside surface of present existing slag retainer all is slick cylinder, and when molten steel buoyancy was big, slag proportion was too big, and the proportion of slag retainer and tail rod does not often reach ideal pushing off the slag effect.
Summary of the invention: the purpose of this utility model is for overcoming the shortcoming that above-mentioned prior art exists, a kind of slag retainer buoyancy that reduces is provided, be equivalent to increase slag retainer proportion, to adapt to slag than the band convex tendon that uses under great, the big situation of molten steel buoyancy or the slag rod guiding rod of groove.
For achieving the above object; the technical solution of the utility model is: a kind of slag rod guiding rod with convex tendon or groove; form with the refractory materials protective layer that is arranged on rebar surface by the reinforcing bar that runs through wherein, it is characterized in that refractory materials protective layer surface is provided with convex tendon or groove.
The utility model is owing to adopt said structure, can be big, the heavy situation of slag is issued to ideal pushing off the slag effect at molten steel buoyancy, and this product can effectively reduce the buoyancy of slag retainer, is equivalent to increase the proportion of slag retainer, alleviates the weight of slag retainer.
Description of drawings: Fig. 1 is provided with the structural representation of convex tendon for outside surface of the present utility model.
Fig. 2 is provided with the structural representation of groove for outside surface of the present utility model.
Embodiment: embodiment of the present utility model is described further a kind of slag rod guiding rod with convex tendon or groove below in conjunction with accompanying drawing; form with the refractory materials protective layer 2 that is arranged on reinforcing bar 1 surface by the reinforcing bar 1 that runs through wherein, it is characterized in that refractory materials protective layer 2 surfaces are provided with convex tendon 3 or groove 4.The impact strength that convex tendon 3 on the tail rod or groove 4 flow downward by molten steel, make slag rod guiding rod and slag retainer together to sinking, thereby reduced the buoyancy of slag retainer, promptly be equivalent to increase the proportion of slag retainer, to be adapted to reaching good pushing off the slag effect under the situation that slag retainer proportion can not improve again.
