Abstract
The invention discloses a hard alloy bar difficultly loosing weld. The hard alloy bar is mainly used for steel slag reaming. The hard alloy bar comprises an elongated alloy bar body, wherein a plurality of through holes are formed on the alloy bar body; and the through holes are uniformly distributed on the alloy bar body in one row. Through the through holes, when products are welded, the welding fluid can effectively fix the alloy bar body and a base body through the through holes, so that the bonding strength is improved, the welding performance of the product is improved, and the welding is difficult to loose.
Description
Technical field
The present invention relates to a kind of cemented carbide bar, especially relate to a kind of main cemented carbide bar that is difficult for sealing-off that is used as the reaming of slag.
Background technique
At present, steel making furnace is the effect that reaches the slag reaming, generally several cemented carbide bars is freezed at steel body surface, forms afterwards helix structure, thereby reaches the reaming effect, about 1200 ℃ of its operating temperatures.But there is poor, the caducous problem of hart metal product welding performance in traditional cemented carbide bar in the application of reality.
Summary of the invention
The object of the present invention is to provide a kind of cemented carbide bar that is difficult for sealing-off, the characteristics that it has good welding performance and is difficult for sealing-off.The cemented carbide bar welding performance that is used for the slag reaming in the prior art is poor to solve, the problem of easy sealing-off.
The objective of the invention is to be achieved through the following technical solutions:
A kind of cemented carbide bar that is difficult for sealing-off, it comprises the alloy bar body, wherein, offers most through holes on the described alloy bar body.
Especially, described through hole is set to a row, is distributed on the alloy bar body.
Especially, described alloy bar body is the long strip structure.
Beneficial effect of the present invention is, the described cemented carbide bar that is difficult for sealing-off compared with prior art increases by row's aperture in the alloy bar body on the constant basis of basic configuration design.Make product in welding, welding fluid can effectively be fixed this product and matrix by aperture, improves its adhesive strength to improve the welding performance of product, makes its difficult drop-off.
Description of drawings
Fig. 1 is the structural representation of the cemented carbide bar that is difficult for sealing-off that provides of the specific embodiment of the invention 1.
Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
See also shown in Figure 1ly, Fig. 1 is the structural representation of the cemented carbide bar that is difficult for sealing-off that provides of the specific embodiment of the invention 1.
In the present embodiment, a kind of cemented carbide bar that is difficult for sealing-off comprises the alloy bar body 1 of long strip, offer most through holes 2 on the described alloy bar body 1, described through hole 2 is a row and is distributed on the alloy bar body 1, the design of described through hole 2 makes product in welding, welding fluid by through hole 2 can be effectively fixedly alloy bar body 1 and matrix, improve its adhesive strength to improve the welding performance of product, make its difficult drop-off.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (3)
