Description
Technical field
The present invention relates to equipment of hot rolling, particularly, relate to a kind of flux-cored wire, use this flux-cored wire to make the method for bending roll of heat coil box, and make and bending roll of heat coil box through this method.
Background technology
Bending roll of heat coil box is the vitals on the hot rolled plate production line, is used for the curling rolling of the strip that roughing is later, thereby the strip of rolling is transported to finish rolling equipment, launches and finish rolling through finish rolling equipment then.In the prior art, the surface of adopting stainless steel or the low-carbon low-alloy steel scolder of hardness about HRC35 to come the built-up welding bending roll usually is to keep certain wearability and hear resistance.But; Because the process tabularium in rolling that strip is curled is not to be curled with the complete angle parallel with the roll surface of bending roll; But being rolled up to the form of outer lug a little, thereby the both sides of the width of strip are not 180 ° when contacting with bending roll, but less than 180 °.Therefore, the two side portions of strip has slight shear action to bending roll, and easily with the roll surface plucking, just the metal with bending roll adhered on the strip when particularly the strip both sides contacted with bending roll, produces sticking meat phenomenon.In addition, when the higher steel band of rolling intensity,, thereby glue meat more easily because the material of the physical property of this steel band and bending roll surface overlaying is approaching.Sticking meat not only influences the surface quality of curling strip, and bending roll has reduced service life because having lost heat-resisting, wear-resisting surface overlaying layer.
Summary of the invention
The purpose of this invention is to provide a kind of can the minimizing glues meat and improves service life and the method and the bending roll of heat coil box of the making bending roll of heat coil box of strip surface quality.
To achieve these goals; The present invention provides a kind of flux-cored wire, and the percentage by weight of the composition of this flux-cored wire is that 0.16～0.6%C, 0.5～1.1%Mn, 0.5～1.9%Si, 13.5～28.0%Cr, 2～6%V, 2～10%Ni, 1～8%Mo, 0.05～0.5%N b, 0.05～0.5%Ti, 0.5～3%W, 1～6%Al, 0.02～0.5%RE, 0～0.03%S, 0～0.03%P, surplus are Fe.

Chromium is the extremely important alloying element of heat resisting steel that is used for making bending roll of heat coil box, can form the fine and close Cr of one deck on the steel surface
2O
3Film.Cr
2O
3Film can stop corrosive gas such as oxygen, sulphur, nitrogen in steel, to spread to a certain extent, also can hinder metallic atom to external diffusion, and in certain temperature range, can also form the composite protection film of the good spinel-type of layer of protecting property.Through on the surface of the heat resisting steel of nickeliferous, chromium, forming layer of Ni O-Cr
2O
3Complex oxide film can strengthen the oxidation-resistance property of steel.The high temperature oxidation resistance of heat resisting steel and its chrome content have certain relation, reach 12% when (below be percetage by weight) when containing chromium, and the high temperature oxidation resistance of heat resisting steel is significantly improved; When containing chromium and reach 22% left and right sides, be extremely good at the high temperature oxidation resistance of 1000 ℃ of following heat resisting steel, form one deck this moment on the surface of heat resisting steel continuously and fine and close oxide-film.Therefore, in the method for the present invention, the flux-cored wire chrome content that forms overlay cladding is not less than 12%.
Aluminium also is oxidation resistant important alloying element in the heat resisting steel, and both economical.Aluminium can form the good Al of layer of protecting property on the steel surface
2O
3Film, its antioxygenic property is superior to Cr
2O
3Film.When containing Al and reach 6%, can make steel under 980 ℃, have good high temperature oxidation resistance; But when containing Al and reach 8%, can significantly reduce the toughness and the weldability of steel.Therefore, in the method for the present invention, the flux-cored wire that forms overlay cladding contains Al and is no more than 6%.
Silicon can form good, the fine and close Si of layer of protecting property on the steel surface
2The O film.Usually, siliceous 1% left and right sides Shi Neng significantly improves the high temperature oxidation resistance of steel in the steel.In addition, the effect that improves high temperature oxidation resistance during the common alloying of silicon, aluminium is superior to the situation of silicon, the independent alloying of aluminium.
In addition, rare earth has significant effect to the high temperature oxidation resistance that improves steel, and reason is: (1) rare earth element can increase the adhesive force between parent metal and the oxide-film, because rare earth oxide has " pinning " effect to parent metal; (2) rare earth element can increase the diffusion of chromium in steel, helps to form Cr on the surface of steel
2O
3Oxide-film.
In addition, Ti, V, Nb have stronger crystal grain thinning and solution strengthening ability, two kinds of elements are above add than separately a kind of add fashionable effective.Wherein, Ti and Al unite the effect ratio that adds crystal grain thinning and have only Ti strong; V, Nb also have stronger precipitation strength ability, and they all are the strong carbide forming elements with Mo, W, and the high-temperature stability of these carbide is better, thereby make the crystallite dimension of surfacing layer metal little, hardness is high, high temperature abrasion resistance and toughness are better.
In addition, vanadium can form the carbide VC (HV is about 2600) of high abrasion, its hardness ratio Cr
7C
3Carbide is much higher.In addition, it is approximate spherical that VC is, and helps highly dispersed and distribute, thereby both reduced the possibility that carbide is scratched, smashes, and protected parent metal again, improved the wearability of material.
Other features and advantages of the present invention will partly specify in the specific embodiment subsequently.
