Description

Broken burnt roller flux-cored welding wire for overlaying welding
Technical field
The present invention relates to a kind of welding material, break the flux-cored wire of burnt roller in particular for built-up welding.
Background technology
Flux-cored wire carries out the wherein class of classifying by manufacture method and welding wire shape.Flux-cored wire medicinal powder package is rolled in thin steel band different cross sectional shapes through rolling the welding wire dialled and be processed into.Flux-cored wire is divided into gas shielded arc welding, non gas shielded welding and submerged-arc welding three kinds of welding wires usually.Be widely used in manufacture of steel structure and alloy welding deposit field at present.
Broken burnt roller is the important spare part on important metallurgical equipment, and its quality, life-span length are directly connected to the tap a blast furnace water yield and the output of steel of steel mill.Broken burnt roller divides upper and lower two groups to install on Coke breakers, and its major function is exactly hard coking coal is broken for the powder that diameter is less than 3.0mm to mix sintering with sintering feed again, and play combustion-supporting effect, coking coal powder size is directly connected to the quality of sintering feed.During broken burnt roller work, its pressure is at 10 ~ 15MP, belongs to high stress material abrasion state, not only will have fine wearability, impact resistance for broken burnt roller, also will have very high intensity and anti-extrusion performance simultaneously.And the broken burnt roller of current domestic use mainly contains two kinds, one adopts 35CrMnSi monoblock cast by using after modifier treatment, this roller life cycle is generally at 4 ~ 6 months, another kind is built-up welding high chromium alloy material after the monoblock cast of employing 35 steel, and the main component of alloy material is: C:2.0 ~ 3.0Si:0.2 ~ 0.6Mn:0.4 ~ 0.8Cr:22 ~ 26Ni:0.1 ~ 0.3Mo:0.35 ~ 0.75W:0.45 ~ 0.9V:0.2 ~ 0.6.Although this roller wearability is fine, but due to high chromium alloy material plasticity and toughness extreme difference, so occur in use procedure that extensive disruption falls block and causes using, roller is shortened service life greatly, general service life, at 6 ~ 8 months, cannot meet brokenly the working condition requirement of burnt roller.
This area is badly in need of having concurrently hardness, toughness, non-oxidizability and crack resistance at present, is exclusively used in brokenly the welding material of burnt roller built-up welding.
Summary of the invention
Technical problem to be solved by this invention is that the hardfacing alloy that burnt roller built-up welding is made has higher hardness and high wear-resisting material abrasion characteristic, also to have good crush resistance and toughness simultaneously, thus improve the service life of broken burnt roller, to meet Production requirement.

C:0.20~0.55%、Si:0.25~0.85%、Mn:0.65~1.85%、Cr:4.5~7.5%、Mo:0.45~2.25%、V:0.21~0.65%、W:1.35~3.55%、Nb:0.25~0.72%、Re:0.21~1.22%;
Also containing one or more in following elements: Ni:0.021 ~ 0.15%, Mg:0.015 ~ 0.25%, Al:0.002 ~ 0.025%; Surplus is Fe and inevitable impurity; Above composition percentage sum is 100%.Wherein, described in above-mentioned flux-cored wire, inevitable impurity and content are by weight percentage: S≤0.03%, P≤0.025%.
In addition present invention also offers the preparation method of above-mentioned flux-cored wire.The method comprises the following steps:
The powder of A, core raw material of getting it filled by component requirements is dried;
B, will fully be mixed to get medicine core powder by material powder;
C, medicine core powder is filled in steel band groove, coated, be drawn into welding wire and get final product.
Beneficial effect of the present invention is: the present invention creatively reforms the composition of flux-cored wire, the hardfacing alloy of the flux-cored wire obtained is made not only to have higher hardness, there is high anti-powerful abrasive wear behavior, and there is good toughness, crack resistance is better, thus the service life substantially increased, be a kind of outstanding broken burnt roller built-up welding flux-cored wire special, there is good application prospect.
Detailed description of the invention
The present invention finds in the research in early stage, because V and Nb has crystal grain thinning, and solution strengthening effect, better effects if when especially more than two kinds of elements adding.V, Nb also have stronger precipitation strength ability, and they and Mo are carbides, add these elements and make that the crystallite dimension of deposited metal is less, hardness improves, toughness improves; Add Mo and can put forward heavy alloyed intensity and toughness, when at the same time containing Cr, Mo can also improve the temper resistance of hardfacing alloy layer greatly; Add B and can form boride, improve the wearability of hardfacing alloy, also can save a large amount of precious metals simultaneously.Add Cr in a large number, improve Cr/C ratio, easily the high rigidity M of the bar form that existence is isolated 7c 3type carbide, than the M of net distribution 3c type carbide, can strengthen the continuity of matrix, thus improves the plasticity and toughness of integral material; Mn can promote the dissolving of strong carbide in austenite, the content of the alloying element in balance carbon compound and austenite, from the precipitation strength and the solution strengthening ability that point to play the elements such as V, Nb, Mo; In addition, improve Mn/S ratio and can also reduce hardfacing alloy hot cracking tendency, prevent alloy-layer from producing pattern cracking and falling block; The adding of Nb hardfacing alloy is had and suppress hydrogen embrittlement preferably, reduce temper brittleness and in heat treatment process, suppress the segregation ability of P on crystal boundary, thus reach the object improving hardfacing alloy toughness.In addition, make inclusion modification because Nb has, the effect of purification crystal boundary and stronger crystal grain thinning, joins the effect that can play in resurfacing welding material and improve overlay properties.
As further improvement, for strengthening the toughness of hardfacing alloy, can also be added one or both in following elements: Ti, Mg or Al.Only have Ti strong because Al and Ti combines the effect ratio adding crystal grain thinning, therefore AI adds and can make hardfacing alloy refinement; Add micro Mg, strong segregation, in crystal boundary and boundary, can make the thin blocking of carbide, and crystal boundary energy and phase boundary can be reduced, and improves interface binding power, makes crack nucleation and expansion be difficult to carry out, thus improve hardfacing alloy plasticity; In addition, the recovery rate adding V and Re is general lower, if but add a certain amount of Al element, just can greatly improve V and Re recovery rate, cost-saving. simultaneously
