The effect of each alloying element and mechanism among the present invention:
C:C is the principal element of decision hardness of steel, is to form pearlitic essential substance, and the hardness and the intensity of the form of carbide in steel and how many decision steel, promptly intensity, the hardness along with the increase steel of C content increases, and the plasticity of steel and toughness descend.Require material to have good plasticity owing to make self-plugging rivet, be difficult for fracture of wire during drawing, and carry out big cold deformation and do not ftracture, so C content should not be too high, consider that the self-plugging rivet worry requires certain intensity, C content should not be low excessively.Therefore, C content is controlled in 0.02～0.15% scope.
Mn:Mn is good reductor and sweetening agent, contains a certain amount of manganese and can eliminate or weaken the fragility that steel causes because of sulphur, thereby improve the processing characteristics of steel.But when manganese content is higher, the tendency that makes the crystalline grain of steel alligatoring is arranged, smelt casting and roll postcooling not at that time, make steel produce white point easily, so Mn content is difficult for too high.So Mn content is controlled at 0.05～1.5%.
Si:Si does not form carbide in steel, be that form with sosoloid is present in ferrite or the austenite, the effect of the intensity of sosoloid and cold deformation cementation index is extremely strong in its raising steel, also significantly improve elastic limit, yield strength and the yield tensile ratio of steel, but reduced toughness, plasticity and the ductility of steel simultaneously to a certain extent.Because of producing the self-plugging rivet material require,,, be controlled at 0.03～0.10% so Si content is low as much as possible so require material to have good toughness, plasticity and ductility through excessive cold deformation.In the scope.
S, P:S, P are intensive crack sensitivity elements, thereby should be low as much as possible, the S too high levels, can form a large amount of MnS, MnS easily separates out at crystal boundary when solidification of molten steel, is rolled into band shape and be mingled with when hot rolling, has reduced the ductility and the toughness of steel, therefore S content is low more good more, and S content is controlled at≤and 0.015%.P can improve the low temperature brittleness transition temperature, and the low temperature impact properties of steel is declined to a great extent, so general requirement P≤0.020%.
Al:Al is that the nitrogen agent is decided in the deoxidation when being used as steel-making, N in Al and the steel forms tiny infusibility AlN particle, the infusible compound that these small and disperseds distribute plays resistance inhibitor action, and then refinement ferrite crystal grain, ferrite crystal grain is excessive, ftracture easily during cold-heading, ferrite crystal grain is too small, and the ferrite crystal boundary will increase, resistance to deformation increases during cold-heading, not yielding, so control ferrite grain size between the 6-10 level, the content of Al is low excessively, the effect of refinement ferrite crystal grain is not obvious, the too high levels of Al can make the flowability of molten steel reduce the numerous Al of formation
2O
3Can locate dross at the mouth of a river, thereby stop up the mouth of a river.Therefore Al content is controlled in 0.01～0.07% scope.
Ca: can cleaning molten steel, improve the purity of steel, make the MnS nodularization in the steel, make the material easy deformation, the potential of performance material during its too high levels, easily forms thick non-metallic inclusion.So Ca content is controlled in 0.001～0.008% scope.
