Abstract
The present invention relates to a tungsten carbide wear-resistant surfacing welding material and its welding electrode, which comprises main material tungsten carbide granules and auxiliary material. The tungsten carbide granule is of submicrofine or nano-level sintered tungsten carbide granule which is made up by using submicrofine or nano-level tungsten carbide powder and cementing phase and adopting power metallurgical production process through the processes of mixing, granulating, sieving and sintering, etc. After the electrode made of said tungsten carbide surfacing welding material is used, its surface quality of welding layer and wear-resistance are greatly are raised.
Description
Technical field
The present invention relates to a kind of carbine abrasion-proof resurfacing welding material and welding rod, it is mainly used in the reinforcement of the steel tooth bit flank of tooth, shirttail and the reinforcement of insert bit shirttail, also can be used for the reinforcement of surface of the work in other technical field.
Background technology
Cobalt-based or iron-based or tungsten carbide of nickel-base apply the wlding material as a kind of stiff dough and are widely used, in oil and field of mining, usually will be greater than 1 micron tungsten carbide powder and bonding cobalt (or iron or nickel etc.) mixing mutually, granulate, sinter tungsten carbide particle into, be that main stuffing is made welding rod with the tungsten carbide particle that sinters into again, use this welding rod tungsten carbide material to be applied the flank of tooth and the shirttail that is welded in rock bit then through oxygen-second piece weldering or atomic H welding, with case hardness and the anti-wear performance that improves them, perhaps can directly the tungsten carbide particle material be applied on the flank of tooth and shirttail of rock bit as binding agent with sodium metasilicate etc., use oxygen-second piece weldering or atomic H welding that it is applied again and be welded on the flank of tooth and shirttail of rock bit, to realize the purpose of above-mentioned strengthening surface.On rock bit, adopt the deposited weldering mode of tungsten carbide surface to play a part important to the raising in its anti-wear performance and service life, yet, development along with modern drilling technology, drilling depth, rate of penetration to drill bit are had higher requirement, and improve the performance that tungsten carbide applies the wlding material, be one of key issue that satisfies above-mentioned requirements at the higher level with the wearability that improves the drill bit flank of tooth.
Summary of the invention
The objective of the invention is to the problem that proposes at above-mentioned prior art and a kind of carbine abrasion-proof resurfacing welding material of optimization process is provided and, further strengthens so that apply the wearability and the anti-erosion property of weldering metal surface by the made tubular tungsten carbide welding rod of this material.
The present invention for the technical scheme that problem adopted of the above-mentioned proposition of solution is: comprise major ingredient tungsten carbide particle and auxiliary material, its difference is the partly or entirely thin or nanoscale cemented tungsten carbide particles for sub-micro of described tungsten carbide particle.
