Description

A kind of plating bolt taut band buckle steel and its manufacturing method
Technical field
The present invention relates to a kind of bolt taut band buckle steel, more particularly to a kind of bolt taut band buckle hot rolling of suitable plating Strip and its manufacturing method.
Background technique
Common bolt taut band buckle is with the general manufacturing procedure of steel: hot rolling board raw material-punch forming-heat treatment-ramming-rolling Optical-electronic plating-assembling.Common bolt taut band buckle of crossing requires hardness 37-41HRC after heat treatment, and tensile strength requires 49KN continuous.For Guarantee plating rear surface zero defect, bolt taut band buckle bayonet is generally made using cold-reduced sheet and is processed raw material.In recent years, for save at This, many producers directly process bolt taut band buckle bayonet using hot rolled steel plate, but it is tight that rear surface mildew pit corrosion defect is electroplated Weight, i.e. influence aesthetic appearance, and reduce the service life.Moreover, as environmental requirement is constantly promoted and production cost problem, downstream User's electroplating technology is also constantly changing, for example, some users eliminate the ramming technique before plating, causes to be made with hot rolled plate former Dotted mildew corrosion default is more serious after the bolt taut band buckle bayonet plating of material production, and qualification rate only up to 30% is electroplated.
CN201380019097.4, C:0.0005%- in " plating steel plate and electroplating steel plate and their manufacturing method " 0.005%, while adding a small amount of alloys such as Cr, Si, Mn, belong to ultra-low-carbon steel, intensity rank is low, is unsatisfactory for bolt taut band buckle and is drawn with steel It stretches and changing firmness requirements；CN200920274053.7, " binding and tightening belt " are a kind of steel grades that puller strap device foregoing invention refers to And there is certain defect in production method, be unsuitable for bolt taut band buckle use demand.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of bolt taut band buckle steel, bolt taut band buckle is used Hardness 37-41HRC after steel heat treatment, plating performance is good, and surface is without corrosion defaults such as mildews.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
A kind of plating bolt taut band buckle steel, it is characterised in that chemical composition comprises the following components in percentage by weight are as follows: C:0.37%~ 0.45%, Si :≤0.30%, Mn:0.2%~0.8%, Cr :≤0.50%, Al:0.015%-0.06%, Cu :≤0.4%, Sb :≤0.2%, impurity element P≤0.030%, S≤0.030%, surplus are Fe and inevitable impurity.
Each alloying component mechanism of action of steel of the present invention detailed below:
C is main solution strengthening element in steel.If C content is lower than 0.37%, it is difficult to ensure that hardness after heat treatment, separately If one side C content is higher than 0.45%, the competency of steel is improved, and toughness plasticity deteriorates, easy brittle failure.Therefore, C content will control 0.37%~0.45%.
Mn is good deoxidier and desulfurizing agent, is the essential elements for guaranteeing the intensity and toughness of steel.Manganese and iron form solid Solution can improve the hardness and strength of ferrite and austenite in steel.Mn forms MnS in conjunction with S, and grain boundaries is avoided to form FeS Caused by fire check influence saw blade steel hot-forming property.Mn is also good deoxidier and increases harden ability simultaneously.Mn contains Measure it is too low, be not able to satisfy heat treatment after high competency requirement, Mn too high levels is easily formed segregated zone influence welding performance, and increasing Add production cost, therefore, the factors such as considering cost and performance requirement, Mn content should be controlled 0.2%~0.80%.
Si is one of common elements in steel, and reducing agent and deoxidier are used as in steelmaking process, and the Si for being dissolved form can be mentioned High-yield strength and ductile-brittle transition temperature, if but Si too high levels will reduce toughness and welding performance.On the other hand, Si is iron element Body formation element can promote steel surface decarburization, and therefore, Si content is not easy excessively high, Si≤0.30%.
Cr is the harden ability element for significantly improving steel, and suitable Cr, which is added, in steel so that C curve is moved to right, and is obtained under identical cooling rate The pearlite piece spacing obtained more refines.For high-carbon steel, the activation energy of carbon spread is can be improved in Cr, and the decarburization for mitigating steel is inclined To.On the other hand, ferrite electrode potential also can be improved in Cr, promotes the surface of steel to form fine and close oxidation film, it is anti-corrosion to improve its Property.Cr too high levels increase cost of alloy, and steel-plate shape is poor, it is difficult to it smooths, therefore, present invention control Cr content≤ 0.50%.
Al:0.015%-0.06%, when smelting, generally make deoxidier with Al, can also refine crystal grain, improve intensity, but same When also easily formed the oxide containing Al be mingled with, influence the punch forming performance of steel.Therefore, Al content control is in 0.015%- 0.06%.
The outstanding role of Cu:Cu≤0.5%, Cu in steel is the weather-resistant performance for improving steel, meanwhile, copper is added also The intensity and yield ratio of steel can be improved, when punching press is indeformable.Cu is often used cooperatively with P in corrosion-resisting steel, and Cu and P can be concentrated in rust In layer, keep its form compact and stable, and the extension of iron rust can be inhibited.When [Cu] lower (about 0.01%), 0.06~0.10%P is added Afterwards, the corrosion resistance of steel improves more than 2 times.When [Cu] is higher (0.4% or so), 0.10%P is added, corrosion resistance only improves 20- 40%, illustrating P, there are extremely complex relationships with Cu.For guarantee punching performance, the present invention in P content be not easy it is excessively high, therefore, A small amount of Cu is added.
Antimony is added in steel in Sb:Sb≤0.2%, can generally make the strength reduction of steel, and brittleness increases, but is added a certain amount of After antimony, the resistance to corrosion and wearability of steel can be improved, therefore≤0.2% antimony is added in steel of the present invention, it is corrosion-resistant to improve Ability and wearability.
P and S is inevitable objectionable impurities in steel, the toughness of their presence meeting severe exacerbation steel.Therefore it to adopt Measure is taken to reduce P the and S content in steel as far as possible.According to the present invention, highest P content is limited in 0.030%, highest S content It is limited in 0.030%.
Carbon content in mentioned component design use, the alloying elements such as addition Mn, Cr, Si, Cu improve steel plate harden ability, quench Hardness and heat resistance guarantee competency after steel plate heat treatment.Micro Nb, V, Al are added simultaneously, refines crystal grain, after improving heat treatment Toughness plasticity guarantees thermal stability and low-temperature flexibility.
A kind of plating bolt taut band buckle manufacturing method of steel, it is characterised in that: including smelting, continuous casting, hot rolling and slow cooling； Continuous casting steel billet thickness is not less than 170mm, and slab upper and lower surface is online or offline sprayed coating, enters after spraying and heats stove heating, slab 500 DEG C of charging temperature or less；When slab on-line spray, thickness 0.2-0.4mm is applied；Under slab when wire spraying, thickness 0.4- is applied 0.6mm；Heating furnace use weak oxide atmosphere, coefficient of excess air 1.1-1.8,1100~1180 DEG C of slab heating temperature, Keep the temperature 3-5h；Smart roughing is all made of high-pressure water descaling, and intensity is greater than 15MPa；Roughing first rolling pass reduction is greater than 30%, open rolling temperature 1050 DEG C~1150 DEG C of degree, 80% or more finish rolling total reduction, 800 DEG C~950 DEG C of finish rolling finishing temperature；Strip goes out finishing mill Afterwards, it is batched with being cooled to 750 DEG C or less greater than 10 DEG C/S~70 DEG C/S cooling rate.
Using converter smelting, LF or RH external refining processing, Al makees deoxidier, guarantees Molten Steel Cleanliness.
For uniform formation, microstructure segregation is controlled, roughing and finish rolling have been required to enough reduction ratios, slab minimum thickness It cannot be less than 170mm.Slab upper and lower surface is online or offline sprayed coating, coating material form protective layer in casting billet surface, have Effect inhibits the generation of surface crystal boundary micro-crack.When slab hot delivery and hot charging sprays, thickness 0.4-0.6mm is applied；Slab is offline to let cool spray Tu Shi applies thickness 0.2-0.4mm.Steel slab surface, ineffective, overweight coating, heating process cannot be completely covered in cover light Middle steel slab surface coating easily forms flaking, does not work.
It is rolled by refining, continuous casting, using hot tandem.To be energy saving, continuous casting billet can be using hot sending warm Dress technique, but require slab charging temperature less than 500 DEG C, it avoids casting billet surface oxidation and decarbonization serious, generates surface grain boundary oxidation Crackle influences plating performance.Slab heating temperature is lower, and 1100~1180 DEG C, and 15MPa or more high-pressure water descaling is used, it goes Except scale on surface, to reduce the skin decarburization oxidation of finished steel plate, guarantee that monoplanar surface decarburized layer deepness is less than plate thickness 1.5%, no grain boundary oxidation, hot rolled plate surface roughness 1.2um or less.
