Abstract
A wear-resistant alloy welding rod relates to metal welding. The utility model provides an iron-based wear-resistant alloy welding rod with good wear resistance and low cost. The iron-based core wire comprises the following components in percentage by weight: c: 1-5%, Cr: 5-20%, Mo: 1-10%, Ni: 0-10%, Si: 0-5%, Mn: 0-8% and the balance of iron. The welding core replaces cobalt with iron, so that the rare element cobalt is saved, the cost of the welding rod is reduced by 95 percent compared with that of a cobalt-based alloy welding rod, the wear resistance of wear-resistant particles is improved by three times, and the wear resistance of the welding rod is improved by one time compared with that of an iron-based wear-resistant alloy welding rod. The welding rod can be used for surfacing of the surfaces of parts under all abrasive particle abrasion conditions so as to improve the abrasion resistance and the service life of the parts.
Description
The utility model is relevant with metal solder.
The welding rod of common welding usefulness, wearability is very poor, wants to improve the anti-wear performance of metal parts, uses the wearproof alloy weld rod built-up welding on the metal parts surface.External use the cobalt-based wearproof alloy weld rod, but cobalt is rare element, also is the important materials of whole world shortage, this welding rod cost height, anti-wear performance are relatively poor.Though at present existing iron-base wear-resistant alloy welding rod, it contains chromium up to 20～30%, so the cost height, and the life-span is lower.
The utility model purpose is to overcome above-mentioned shortcoming, proposes a kind of with the wearproof alloy weld rod of iron for cobalt.
The new wearproof alloy weld rod that proposes (as figure) is that the coating 2 by iron-based core wire 1 and its external application constitutes.The composition of core wire and shared percentage by weight thereof are respectively: C:1～5%, Cr:5～20%, Mo:1～10%, Ni:0-10%, Si:0～5%, Mn:0～8%, all the other content are iron.The molybdenum that adds some to guarantee good martensitic matrix tissue and hardness, can carry out machining by annealing softening, and quench hardening again improves the case hardness of overlay cladding.With the electric welding electrode coating, compositions of surfacing metal and shared percentage by weight thereof are respectively: marble: 10～50%, magnesia: 0～20%, fluorite: 20～70%, quartz: 0～10%, ferrochrome: 0～20%, ferromanganese in the core wire external application: 0～10%, Aluminum powder: 0～20%, graphite: 0～10%.
The wearproof alloy weld rod that the utility model provides for cobalt, has been saved rare element cobalt with iron, and this welding rod improves three times than cobalt-based wearproof alloy weld rod abrasive wear resistance performance, doubles than existing iron-based welding rod anti-wear performance; Reduce by 95% than cobalt-based wearproof alloy weld rod cost.This welding rod built-up welding is supported on the aerofoil at mining down-the-hole drill virtual calibrator for instrument transformer, improved and supported the abrasive wear resistance performance of aerofoil and the anti-breakaway performance of overlay cladding, prevent hole deviation, guarantee that the hole deviation rate less than 1%, makes improve three times the service life of virtual calibrator for instrument transformer.This welding rod can be used for the built-up welding of the piece surface under the various abrasive wear conditions, to improve wear-out part service life.
Claims (2)
1, a kind of wearproof alloy weld rod with iron-based core wire is characterized in that the composition of core wire and shared percentage by weight thereof are respectively: C:1～5%, Cr:5～20%, Mo:1～10%, Ni:0～10%, Si:0～5%, Mn:0～8%, Fe: surplus.
2, according to the described wearproof alloy weld rod of claim 1, it is characterized in that the core wire external application with coating, the composition of coating and shared percentage by weight thereof are respectively: marble: 10～50%, magnesia: 0～20%, fluorite: 20～70%, quartz: 0～10%, ferrochrome: 0～20%, ferromanganese: 0～10%, Aluminum powder: 0～20%, graphite: 0～10%.
