Embodiment Construction

[0010] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0011] see figure 1 as shown, figure 1 It is a schematic structural view of the difficult-to-de-solder hard alloy strip provided in Embodiment 1 of the present invention.

[0012] In this embodiment, a cemented carbide strip that is not easy to desoldering includes a long strip-shaped alloy strip body 1, and a plurality of through holes 2 are opened on the alloy strip body 1, and the through holes 2 are evenly distributed in a row. On the alloy bar body 1, the through hole 2 is designed so that when the product is being welded, the welding liquid can effectively fix the alloy bar body 1 and the matrix through the through hole 2, and improve its bonding strength to improve the welding performance of the product. It does not fall off easily.

[0013] The above embodiments have only set forth the ba...

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 [0001] The invention relates to a cemented carbide strip, in particular to a cemented carbide strip which is mainly used for reaming steel slag and is not easy to be desoldered. Background technique [0002] At present, in order to achieve the effect of steel slag hole expansion, steelmaking furnaces generally weld several cemented carbide strips on the surface of the steel body, and then form a spiral structure to achieve hole expansion. The working temperature is about 1200°C. However, the traditional cemented carbide strips have the problems of poor welding performance and easy falling off of cemented carbide products in practical applications. Contents of the invention [0003] The object of the present invention is to provide a hard alloy strip that is not easy to desolder, which has the characteristics of good welding performance and not easy to desolder. In order to solve the problems of poor welding performance and easy desoldering of cemented carb...
