Abstract
The present invention relates to a high-temperature and wear-resistant welding rod for overlaying welding, which is essentially formed by pressing and coating mixed electrode coating on a core wire made of low carbon steel, wherein the electrode coating is composed of ferrochromium, ferrotungsten, ferrotitanium, ferromanganese, boron carbide, ferromolybdenum, nickel powder, feldspar, marble, rutile, titanium pigment, rare earth ferrosilicon, graphite and cellulose. The high-temperature and wear-resistant welding rod for overlaying welding obviously increases the hardness and toughness of an overlaying welding layer; with high technological performance for welding, the welding rod can be used with alternating current or direct current; preheating can be left out at the time of overlaying welding in a single layer; the welding rod can be directly used in the state of welding without requirement for heat treatment; the present invention has the advantages of simple technology and low manufacturing cost.
Description
The present invention relates to high-temp antiwear surfacing welding electrode, relate to specifically a kind ofly be prepared from surfacing welding by multiple alloying constituent with good high-temperature wearability.
At present, " wearing and tearing " have become metal material and the main failure forms of the machine components made by it, and cause tremendous loss to national economy thus.Therefore, develop effective and economic high-abrasive material national economy is had significant meaning.The quick-wear surface of part adopts appropriate overlay cladding can significantly improve its service life, and this is to reasonable use material (particularly saving precious metal), improves product design, enhances product performance, reducing cost greatly has crucial meaning.Domestic red hardness welding rod preferably mostly is the cobalt-based surfacing welding, as D822, D812 etc.This type of welding rod costs an arm and a leg, and can not bear the abrasive wear under the hot conditions.Be 42～48 as the Vadaplet company of Britain, its hardness range of similar welding rod HRC that the Ka Situolinetedi company of Switzerland produces abroad, the toughness of deposited metal is relatively poor.So optimized alloy system, development anti-wear performance high-temp antiwear surfacing welding electrode good, the cost relative reduce become the industry mechanical wear working condition problems extremely to be solved such as metallurgy, coal, chemical industry.
The object of the present invention is to provide a kind of overlay cladding to be formed by multiple alloying element, can satisfy and working under the hot conditions more than 600 ℃, red hardness preferably, preparation is simple, high-temp antiwear surfacing welding electrode with low cost.
The object of the present invention is achieved like this:it forms electrode coating through mixing by ferrochrome, ferrotungsten, ferrotianium, ferromanganese, boron carbide, molybdenum-iron, nickel powder, feldspar, marble, rutile, titanium dioxide, rare earth ferrosilicon, graphite and cellulose substantially, extrusion forms on low carbon steel welding core, it is characterized in that electrode coating is the high-temp antiwear surfacing welding electrode that the feedstock production by following weight parts (kg) forms; Ferrochrome 25-30 ferrotungsten 25-30 ferrotianium 3-8 ferromanganese 5-10 boron carbide 5-10 molybdenum-iron 5-10 nickel powder 5-10 feldspar 3-7 marble 5-10 rutile 5-10 titanium dioxide 2-5 rare earth ferrosilicon 2-5 graphite 0-2 cellulose 0-2.
The present invention compared with prior art, it has significantly improved the hardness and the toughness of overlay cladding, built-up welding hardness is HRC62～66 under the normal temperature, hardness still remains between HRC45～50 under 600 ℃ of hot conditions; Welding technological properties is good, but AC/DC; Single-layer surfacing need not preheating; Can directly need not heat-treat in as-welded use down; And technology of the present invention is simple, and manufacturing cost is also cheaper.
Further specify the present invention below in conjunction with embodiment
Embodiment 1
With ferrochrome 28kg, ferrotianium 6kg, boron carbide 10kg, nickel powder 5kg, marble 8kg, titanium dioxide 4kg, graphite 1kg, ferrotungsten 30kg, ferromanganese 10kg, molybdenum-iron 6kg, feldspar 6kg, rutile 7kg, rare earth ferrosilicon 4kg, cellulose 2kg, the difference crushing screening, ferroalloy 60 order all-pass mistakes wherein, all the other nonmetallic substance 40 order all-pass mistakes, after mixing, in mixing in 25% the ratio adding dry powder, adopt the hydraulic press extrusion with 2.8M, 48 ° of Be potassium-sodium water glasses on the H08A steel wire.Extrusion is after 24 hours low temperature dries, and hyperthermia drying promptly gets high-temp antiwear surfacing welding electrode then, and built-up welding hardness is HRC66 under the normal temperature, and hardness remains on HRC50 under 600 ℃ of conditions.
