Definitions

  • the present invention relates to a steel sheet used as a material for a can produced by drawing, ironing, stretching and succeeding diameter reduction forming as represented by the production of a two-piece can and a method for producing the steel sheet.
  • the present invention provides a steel sheet for an ultra-thin can, capable of being produced with high productivity, small earing and good neck wrinkling resistance and a method for producing the steel sheet.
  • two-piece cans In the field of manufacturing beverage cans and food cans, etc., the production amount of cans wherein bottoms and walls are integrally formed in one body, called two-piece cans, is increasing.
  • a two-piece can In a two-piece can, generally, in order to obtain a required can height, a method for increasing the can wall height by ironing or stretching after drawing process is adopted, as is represented by a method for manufacturing a DI can or a DTR can.
  • the present invention provides a steel sheet used for a two-piece can produced by drawing and ironing or stretching, having high drawability and avoiding
  • the anti-wrinkling property is improved, as crystal grain size becomes coarser, as the strength of ⁇ 100 ⁇ plane becomes higher and the strength of ⁇ 111 ⁇ plane becomes lower in crystalline texture, and as precipitates become coarser in size and lower in density.
  • the present invention has been completed by further considering the workability, etc. of a two-piece can annealed at a relatively low temperature for restraining heat-buckle during annealing process.
  • the inventors Based on the finding that the anti-wrinkling property is influenced by the amount and size of AlN and MnS, the inventors have further studied in detail and obtained the result that the anti-wrinkling property can be evaluated by restricting the ratio of N existing as Al nitrides to N content or the size distribution of AlN and MnS. That is, according to the present invention, a steel sheet for a two-piece can with a thickness of 0.19mm or less and having excellent neck wrinkling resistance and anti-earing property can be produced on condition that AlN and MnS satisfy the following requirements:
  • C forms cementite in steel when the content is high.
  • coarse cementite When coarse cementite is exposed on a surface, it may cause the deterioration of the plating properties of a steel sheet. Further, the coarse cementite could be a starting points cracks during ironing, stretching or flange forming in the process for manufacturing a can. It is desirable, therefore, that the upper limit of C content is set to 0.08%.
  • the properties can be markedly improved by setting the upper limit of C to 0.06% or less.
  • a reduction of the carbon content of less than 0.008% for controlling aging property it is not desirable from the aspect of insufficient can strength and the increase of decarburization cost because of the existence of C in solid solution. From these aspects, it is desirable to set C content to at least 0.008%. Further, to obtain a soft material with high ductility desirable for a two-piece can at a low cost without using a vacuum degassing process, it is desirable to limit the C content within the range between 0.02 and 0.04%.
  • N is an important element that controls the formation of nitrides. Too much N generates many nitrides, and hence the object of the present invention is hard to achieve. It is desirable, therefore, the upper limit of N be set to 0.0040%. If N is reduced to 0.0020% or less by sufficiently applying a vacuum degassing treatment, it is further desirable because the amount of nitrides generated is decreased and hence the target properties are improved.
  • the Si content is set to 0.05% or less. Further, more desirably, it should be set to 0.029% or less.
  • the Mn content is set within the range between 0.04 and 0.4%. Further, more desirably, it should be set within the range between 0.15 and 0.25%.
  • the P content is set to 0.04% or less. Further, more desirably, it should be set to 0.010% or less.
  • the S content is set to 0.04% or less. Further, more desirably, it should be set to 0.020% or less.
  • Al is, like N, an important element that controls nitrides, which is an important requirement of the present invention. From this aspect, it is desirable that the Al content is set within the range between 0.02 and 0.10%. Further, more desirably, it should be set within the range between 0.050 and 0.080%.
  • the present invention mainly utilizes Al nitrides as precipitates and does not mainly utilize compounds of B, Ti and V, etc. Therefore, B, Ti and V, etc. are not added intentionally.
  • Nitrides are mainly composed of AlN and hence the following relation must be satisfied; (N existing as AlN)/(N content)> 0.5.
  • N existing as AlN is a value obtained by converting the total amount of AlN into the amount of N, wherein the amount of Al in residuals when a steel sheet is dissolved in an iodine alcohol solution is analyzed and that total amount is regarded as composing AlN.
  • the size distributions of AlN and MnS are important factors for improving neck wrinkling resistance.
  • the present invention is preferable that, for AlN, the ratio of the number of AlN with a diameter of 0.10 ⁇ m or less to the number of AlN with a diameter of at least 0.005 ⁇ m is 10% or less and the average diameter of AlN is 0.01 to 0.10 ⁇ m, and that, for MnS, the ratio of the number of MnS with a diameter of 0.03 ⁇ m or less to the number of MnS with a diameter of at least 0.005 ⁇ m is 50% or less and the average diameter of MnS is 0.03 to 0.40 ⁇ m.
  • the size distribution can also be obtained by photographing the visual field and carrying out image analysis, etc.
  • work hardening behavior of a material including the Bauschinger Effect
  • fine precipitates greatly influence the work hardening behavior of a material.
  • the quantitative and qualitative analyses of fine precipitates are not regarded as perfect even with the latest technologies and could cause large errors. Therefore, the present invention specifies the claims in relation to coarse precipitates in which measuring errors are expected to be reduced.
  • MnS of an elongated shape can occasionally be observed, and for MnS with anisotropic shape, the average of the longest diameter and the shortest diameter is defined as the diameter of the precipitate.
  • the heat history over the overall manufacturing processes is important.
  • the influence of slab heating temperature and coiling temperature is large, and therefore it is necessary to control the slab reheating temperature to within a predetermined range.
  • a slab reheating temperature is determined in combination with a coiling temperature (CT).
  • CT coiling temperature
  • a steel sheet according to the present invention can be obtained without specifying the coiling temperature.
  • the precipitation of MnS during slab heating proceeds by setting a slab reheating temperature at a low temperature of 1150°C or less, the amount of fine MnS, which precipitates with a temperature drop during hot-rolling, is reduced, and thus the same effect as the above-mentioned AlN can be obtained. Further, in this case, it is thought that the coiling temperature need not be specified because the precipitation of AlN is also promoted during slab heating.
  • Cold-rolling reduction ratio is in the range between 82 and 94%. The figure is defined considering the productivity in producing a thin steel sheet and the suppression of in-plane anisotropy from the aspect of material quality.
  • the productivity of hot rolling goes down and in-plane anisotropy increases because the thickness of a hot band is required to be thinner.
  • the cold-rolling reduction ratio is high, the burden on the cold-rolling process becomes heavy and in-plane anisotropy also increases.
  • Annealing temperature is in the range between the recrystallization temperature and 720°C. The reason is that securing recrystallization is necessary for obtaining good ductility and the deterioration of productivity in the annealing process is of concern at a temperature exceeding 720°C. Further, more desirably, the temperature should be in the range between 650 and 670°C.
  • re-cold-rolling reduction ratio (RCR) after annealing is in the range between 1 and 10%. This is because the effect of re-cold-rolling is obtained at a re-cold-rolling reduction ratio of at least 1%, while too high re-cold-rolling reduction ratio causes the deterioration of workability due to the hardening of a material. Further, more desirably, the re-cold-rolling reduction ratio is in the range between 1 and 2%.
  • the effect of the present invention does not disappear even if strengthening elements such as Si, Mn and P, etc. are added in a large quantities, instead of employing 2CR, to increase the strength of a steel sheet.
  • a steel sheet according to the present invention is also used as a substrate for a surface treated steel sheet.
  • the surface treatment does not hurt the effect of the present invention at all.
  • a steel sheet according to the present invention when it is used as a surface treated steel sheet for a can, is usually coated with tin or chromium (tin-free), etc. Further, a steel sheet according to the present invention is also used as a substrate for a laminated steel sheet, which is coated with organic film and has been in use recently, without hurting the effect of the present invention.
  • Cans with a thickness of 125 ⁇ m at the portion where neck-forming is to be performed were produced while maintaining the drawing ratio and ironing ratio constant and the same multi-stage diameter reduction as is applied to conventional actual can manufacturing was applied to the cans and neck wrinkling resistance was evaluated by the value of a critical diameter reduction ratio calculated by the following equation (2) as a threshold of generating wrinkle. Since the allowance of material quality in actual operation becomes larger as the critical diameter reduction ratio becomes higher, wrinkle generation can be suppressed.
  • Critical diameter reduction ratio (initial diameter - diameter at the time of wrinkle generation)/(initial diameter)
  • Heat-buckle was evaluated by the occurrence of heat-buckle when a steel sheet was processed in a continuous annealing line at the temperature of recrystallization temperature + 40°C.
  • Figure 1 shows the relationship between the size distribution of MnS and neck wrinkling resistance for steel sheets with 0.03% of C in weight percent. Steel sheets having MnS size distribution within the range specified by the present invention have good neck wrinkling resistance.
  • the effects of MnS size distribution are separately shown by each slab reheating temperature category. The neck diameter reduction property is improved when slab reheating temperature is 1250°C or less and coiling temperature is at least 690°C even though the size distribution of MnS is almost the same.
  • the rate of wrinkle generation during neck diameter reduction can be reduced. Further, since a steel according to the present invention shows good properties even with an annealing temperature lower than the temperature for a conventional steel, the generation of heat-buckle can be avoided and highly efficient production of a material for an ultra-thin can is made possible.
