Abstract

The invention discloses a strong-impact-resistant and wear-resistant surfacing electrode, which is prepared by, by weight parts, 40-45 parts of core and 55-60 parts of covering. The core is H08A. The covering comprises, by weight parts, 1-4 parts of marble, 1-4 parts of fluorite, 10-25 parts of rutile, 10-25 parts of titanium dioxide, 10-20 parts of ferrous powder, 0.2-1.5 parts of ferrotitanium, 30-60 parts of mid-carbon ferro-manganese, 1-5 parts of high-carbon ferrochrome, 10-20 parts of chromium metal, 2-10 parts of ferromolybdenum, 1-4 parts of nickel powder, 0.5-2 parts of sodium carbonate, 0.5-2 parts of rare earth ferrosilicon and 10-20 parts of sodium potassium silicate. The surfacing electrode has the advantages of fine welding manufacturability, high hardening rate in surfacing metalworking and excellent resistance to chipping type impact and wear, prolongs the service life of workpieces greatly and reduces maintenance cost thereof, and has better economic and social benefits.

Description

technical field [0001] The invention relates to a surfacing welding electrode, in particular to a strong impact and wear-resistant surfacing welding electrode with excellent impact resistance, corrosion resistance and wear resistance. Background technique [0002] As we all know, the wear of workpieces working under the conditions of impact and abrasive wear is very serious, which directly leads to the increase of production costs and adds a great burden to the enterprise. For example, the jaw crusher used for ore crushing is usually made of high manganese steel with good anti-chisel abrasive wear performance. However, due to the strong impact and wear of the ore when the jaw crusher is working, the wear is still very serious, and a new jaw plate needs to be replaced in a few days. If the worn part can be repaired by welding, it will bring considerable economic benefits to the enterprise. Contents of the invention [0003] The present invention is proposed in view of the...
