Abstract
The surfacing electrode for roller adopts H08A steel as core wire, the coating is composed of (by weight) high carbon chrome iron 8-10%, molybdena-iron 3-5%k, metal tungsten 0.5-1.5%, high-carbon ferromanganese iron 1-3%, lithium carbonate 0-1% and carboxymethyl cellulose 1-2%. Said electrode is suitable for the surfacing welding of 9Cr2, 9CrSi, 9CrV, 9Cr2Mo, 9CrW 9Cr2MoV etc. roller steel, and also suitable for the surfacing welding of other carbons teel and alloy steel. The hardness of the surfacing welding layer under normal atmospheric temp. HRc is greater than or equal to 60. There are no need of preheating befor ewelding and heat-treatment after welding. There is no cracking in surfacing welding layer. It can be used directly under welding state.
Description
The present invention relates to a kind of surfacing welding electrode for roller, the high cracking resistance of particularly a kind of roll is exempted from the preheating surfacing welding rod.
At present, for guaranteeing the surfacing welding electrode for roller surfacing hardness more than HRc45, reach overlay cladding and do not crack, need before the weldering the workpiece preheating, postwelding must carry out temper again, and owing in the high-temperature metallurgical reaction process, exist complicated interaction between each constituent of coating, adopt empirical method, traditional welding rod prescription designs that its blindness is big, and tested number is big, and the cycle is long, the expense height, and difficulty is found out optimum formula.
The object of the present invention is to provide not preheating before a kind of weldering, postwelding is no longer heat-treated, and high cracking resistance, high rigidity, high abrasion, the resistant to elevated temperatures surfacing welding of crackle do not appear in overlay cladding.
For solving above-mentioned task, the solution that the present invention adopts is:
This composition contains following component: high carbon ferro-chrome 8～10%, molybdenum-iron 3～5%, vanadium iron 0～3%, tungsten 0.5～1.5%, high carbon ferromanganese 1～3%, graphite 1～1.5%, ferrotianium 8～9%, rare earth alloy 2～4%, marble 44～48%, titanium dioxide 1～3%, fluorite 12～15%, mica 1～3%, wollastonite 4～5%, lithium carbonate 0～1%, carboxymethyl cellulose 1～2%.
Below all be weight percentage, the percentage sum should be 100%.
Compared with prior art, the present invention has the following advantages:
1, is used for 9Cr
2, 9CrSi, 9CrV, 9Cr
2Mo, 9CrW, 9Cr
2The built-up welding of roll stells such as MoV does not need preheating before the weldering, postwelding is no longer heat-treated under the normal temperature, and crackle does not appear in crack resistance height, layer, and weldment can directly use down as-welded.
2, deposited metal layer Rockwell hardness number HRc 〉=60, wearability is good, has improved 1～3 times of service life of workpiece, and rehabilitation cost only is 1/10 to 1/3 of a new roll price.
3, deposited metal is high temperature resistant, can work under 500～600 ℃ of high temperature.
4, advanced cad technique is adopted in the welding rod prescription design, can obtain best welding rod prescription, and usability of electrode is good, but DC-AC two-use, striking is easy, arc stability, and it is little to splash, and it is easy to take off slag.
5, of many uses, except that being used for 9Cr
2Outside the series of rollers built-up welding, also can be used for the built-up welding of basic, normal, high carbon steel and basic, normal, high carbon alloy steel.
The present invention will now be further detailed embodiment:
