- Patent Document 1 Japanese Patent Application Laid-Open No. 5-195073
- Patent Document 2 JP 59-50125 A
- Patent Document 3 Japanese Patent Application Laid-Open No. Sho 62-30848
- Patent Document 4 JP 2000-26921 A Currently, a steel plate having a yield strength of about 420 MPa is used for the can body of a three-piece can.
- the steel sheet is required to have a thickness of several percent, and a yield strength of 450 MPa or more is required to maintain the strength of the can body in response to such a demand.
- slab corners In addition, when making slabs by melting steel containing a lot of C or N, in the continuous forging process, the corners of the long and short sides (hereinafter referred to as slab corners) in the slab cross section are broken. May occur.
- the slab In vertical bending and bending continuous forging machines, the slab is subjected to bending deformation and unbending deformation (vertical bending type only) at high temperatures. Steels rich in C and N have poor hot ductility, and cracks occur during this deformation. If cracks occur in the slab corner, surface grinding and other operations are required, which results in a decrease in yield and an increase in cost.
- the above-described conventional high-strength steel plates contain a large amount of solid solution strengthening elements C and N, and there is a possibility of partial cracking in the slab corner in the continuous forging process. high.
- the present invention has been made in view of such circumstances, and provides a steel plate for cans that has a yield strength of 450 MPa or more and that does not cause cracks at slab corners in a continuous forging process. With the goal. Disclosure of the invention The present inventors conducted intensive research to solve the above problems. As a result, the following knowledge was obtained.
- a high-temperature tensile test was performed on a steel having the same composition as the steel in which slab corner cracks occurred, and when the fracture surface of the brittle cracks was observed with a scanning electron microscope, cracks occurred along the Fe grain boundaries. Presence of precipitates was observed on the grain boundaries. When this precipitate was analyzed, it was MnS and A1N. These compounds have poor deformability and are thought to have the effect of making the grain boundaries brittle. When the content of C and N is large, the grains are strengthened by solid solution strengthening, so it is difficult to stretch, and it is considered that cracks are easily caused by concentration of stress at brittle grain boundaries.
- solid solution strengthening using solid solution strengthening elements such as N, solid solution strengthening with P and Mn, and grain refinement strengthening.
- solid solution strengthening elements such as N
- solid solution strengthening with P and Mn solid solution strengthening with P and Mn
- grain refinement strengthening As a result, a yield strength of 450 to 470 MPa is obtained.
- S and / or A1 content low, it is possible to prevent cracking at a part of the slab corner during continuous forging even though it contains a large amount of C and N.
- the slab corner temperature in the region where the slab undergoes bending deformation or unbending deformation (hereinafter referred to as the straightening zone) during continuous forging.
- the straightening zone the slab corner temperature in the region where the slab undergoes bending deformation or unbending deformation
- a steel sheet for high-strength cans has been completed by managing components based on the above knowledge.
- the percentages indicating the components of steel are all mass%.
- the “high-strength steel plate for cans” is a steel plate for cans having a yield strength of 450 MPa or more.
- the steel plate for cans of the present invention is a steel plate for high strength cans having a yield strength of 450 MPa or more.
- the steel sheet for cans it is essential to achieve a strength of a predetermined level (yield strength of 450 MPa or more) after continuous annealing, temper rolling, and paint baking. Meet these characteristics
- the amount of c added as a solid solution strengthening element is important, and the lower limit of the C content is 0.03%.
- the upper limit is made 0.10%.
- it is 0.04% or more and 0.07% or less.
- Si is an element that increases the strength of steel by its solid solution strength, but if added in a large amount, corrosion resistance is significantly impaired. Therefore, it is set to 0.01% or more and 0.5% or less.
- P is an element having a large solid solution strengthening ability, but if it is added in a large amount, corrosion resistance is significantly impaired. Therefore, the upper limit is set to 0.100%. On the other hand, dephosphorization cost becomes excessive to make P less than 0.001%. Therefore, the lower limit of P content is 0.001%.
- S is an impurity derived from blast furnace raw material, but combines with Mn in steel to produce MnS. Precipitation of MnS at grain boundaries at high temperatures can cause embrittlement. On the other hand, Mn addition is necessary to ensure strength. It is necessary to reduce the amount of S to suppress MnS precipitation and prevent cracking at the slab corner. Therefore, the upper limit of the amount of S is 0.020%. Preferably, it is 0.005% or less. In addition, desulfurization costs are excessive to make S less than 0.001%. Therefore, the lower limit of S content is 0.001%.
- A1 acts as a deoxidizer and is an element necessary to increase the cleanliness of steel.
- A1 combines with N in the steel to form A1N. This, like MnS, segregates at the grain boundaries and causes high temperature brittleness.
- N is contained in order to ensure strength, it is necessary to keep the A1 content low in order to prevent brittleness. Therefore, A1
- the upper limit of the amount is 0.10%. Preferably, it is 0.04% or less.
- steels with an A1 content of less than 0 ⁇ 0 1% may result in insufficient deoxidation. Therefore, the lower limit of the A1 amount is 0.01%.
- N is an element that contributes to solid solution strengthening. In order to exert the effect of solid solution strengthening, it is desirable to add 0.05% or more. On the other hand, if added in a large amount, the hot ductility deteriorates, and even if the S content is regulated within the above range, slab corner cracks cannot be avoided. Therefore, the upper limit of N content is 0.012%.
- Mn Mnf- ⁇ [mass 0/0] - 1 ⁇ 71 Mnf when the XS [wt%]: 0. 3 ⁇ 0 6 Mn increases the strength of steel by solid solution strengthening, the crystal grain size Make it smaller.
- Mn combines with S to form MnS
- the amount of Mn that contributes to solid solution strengthening is considered to be the amount obtained by subtracting the amount of Mn that can form MnS from the amount of added Mn.
- Mnf Mn [mass. / 0 ] — 1. 71 XS [mass%].
- the steel of the present invention does not contain a pearlite structure.
- the pearlite structure is a structure in which a ferrite phase and a cementite phase are precipitated in a layered form.
- voids crack due to stress concentration and the ductility in the temperature range below the transformation point decreases.
- Three-piece beverage cans are necked to reduce the diameter of both ends of the can body 2009/056015 Processing may be performed. In addition to the necking process, flange processing is applied to tighten the lid. If the ductility at room temperature is insufficient, the steel sheet will crack during these severe processes. Therefore, in order to avoid a decrease in room temperature ductility, the structure should not include a pearlite structure.
- Hot rolling can be performed according to a conventional method.
- the thickness after hot rolling is not particularly specified, but it is preferably 2 mm or less in order to reduce the burden of cold rolling.
- the finishing temperature is stipulated, but the finishing temperature is 850 to 930 ° C in order to obtain a uniform structure, and the scraping temperature is 550 to 650 to prevent excessive coarsening of the ferrite particle size. It is preferable to set to ° C.
- Cold rolling is preferably performed at a rolling rate of 80% or more. This is to destroy the pearlite structure formed after hot rolling. If the cold rolling rate is less than 80%, the pearlite structure remains. Therefore, the rolling rate of cold rolling should be 80% or more.
- the upper limit of the rolling rate is not specified, but an excessive rolling rate is preferably 95% or less because it causes an excessive load on the rolling mill and leads to defective rolling.
- Annealing is performed after cold rolling.
- the annealing temperature at this time should be less than the transformation point. If the annealing temperature is above the transformation point, an austenite phase is formed during annealing, and it transforms to a pearlite structure during the cooling process after annealing. Therefore, the annealing temperature should be less than the transformation point.
- known methods such as continuous annealing and patch annealing can be used. After the annealing process, temper rolling, plating, etc. are performed according to conventional methods.
- the obtained steel slab was reheated at a temperature of 1250 ° C, then hot-rolled in a finish rolling temperature range of 880 ° C to 900 ° C, and averaged 20-40 ° C / s until scraping
- the sample was cooled at a cooling rate and cut in a scraping temperature range of 580 to 620 ° C.
- the steel sheet was cold-rolled at a rolling reduction of 90% or more to produce a steel plate for cans having a thickness of 0.17 to 0.2 mm.
- the obtained steel plate for cans was heated at 15 ° C / sec, and subjected to continuous annealing at the annealing temperatures shown in Table 1 for 20 seconds. Next, after cooling, temper rolling was performed at a rolling rate of 3% or less, and ordinary chromium plating was continuously applied to obtain tin-free steel.
- the plated steel sheet (tin-free steel) obtained as described above was subjected to a heat treatment equivalent to 210 ° C for 20 minutes and then subjected to a tensile test. Specifically, the steel sheet was processed into a JIS No. 5 test piece to obtain a tensile test piece, which was measured at 10 mm / min using an instrument type tester and the yield strength was measured.
- a notch tensile test was also conducted to evaluate the cold ductility.
- the steel sheet was processed into a tensile test piece with a width of 12.5 mm, a parallel part length of 60 mm, and a target distance of 25 thighs, and a V-notch with a depth of 2 mm was added to both sides of the parallel part for tensile testing. Provided. Elongation at break of 5% or more was accepted: ⁇ , and less than 5% was rejected: X.
- the steel sheet cross section was polished, the grain boundaries were etched with nital, and the structure was observed with an optical microscope.
- Nos. 9 and 10 of the comparative examples are insufficient in strength because they have less Mnf and N, respectively.
- No. 11 and 12 have a large amount of S and A1 respectively, so that No. 13 and 14 have slab corner surface temperatures in the upper and lower straightening bands that exceed 800 ° C outside the scope of the present invention. Cracks occurred at the slab corner because it was in the region below ⁇ 900 ° C.
- No. 15 has a structure containing pearlite at room temperature because the annealing temperature is above the transformation point, and the room temperature ductility is insufficient. Industrial applicability
