Definitions
- the present invention relates to a method for producing a cold rolled stainless steel strip having high gloss.
- the use of low-viscosity rolling oil or the use of small-diameter work rolls during cold rolling reduces the amount of oil brought into the roll bite.
- a widely adopted method is to increase the transfer rate of the adjusted roll surface roughness to the surface of the steel strip.
- Japanese Patent Application Laid-Open No. 7-155809 discloses a method of obtaining high gloss by regulating the roughness of a rolling roll.
- the feature is that the last two or more passes are rolled on smooth rolls with a center line average roughness Ra: 0.01 to 0.06 m, or are further lubricated at a rolling reduction of 0.3 to 3.0% using the same smooth nozzle.
- Temper rolling is performed.
- Japanese Patent Application Laid-Open No. 1-197004 there is also known a method of performing final pass rolling using a mirror-finished work roll having a Young's modulus of 31000 to 54000 kg mm 2 in the production of metal foil having excellent surface gloss. Have been.
- the desired glossiness cannot be obtained when the rolling speed, particularly the rolling speed in the final pass, is increased, so that the production efficiency of the stainless steel strip is low.
- the rolling speed particularly the rolling speed in the final pass
- an object of the present invention is to provide a method capable of overcoming these difficulties and producing a stainless steel cold-rolled steel strip having high gloss with higher production efficiency than the conventional one. Disclosure of the invention
- the present invention relates to a method for producing a cold rolled stainless steel strip having high gloss, comprising: a plurality of passes, a final pass of cold rolling performed continuously, a Young's modulus: more than 54000 kg ⁇ nm 2 , and a centerline average roughness Ra: ⁇ . ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇
- FIG. 1 is a graph showing the relationship between glossiness and final pass rolling speed in Examples and Comparative Examples of the present invention.
- the Young's modulus is the final pass of cold rolling performed in a plurality of consecutive passes.
- the Young's modulus of the work roll used in the final pass rolling was 54000kg mm 2 than the case of using the Young's modulus 54000kg mn ⁇ less than the work rolls, the final connexion by the amount of reduction rolling pass rolling load
- the amount of oil in the roll bite increases, resulting in an increase in the amount of oil in the roll bite, which tends to cause a width-wise linear defect called an oil pit, resulting in high gloss. This is because the range of the reduction amount is too narrow and the number of passes increases, and the effect of improving the production efficiency cannot be obtained.
- the reason why the center line average roughness Ra of the work roll is set to 0.10 m or less is that when the Ra of the work roll exceeds 0.10 m, the polishing pattern at the time of rubbing polishing remains after the skin pass, and the value as quality is reduced. Because, it cannot be commercialized.
- the reason why the Ra of the entrance side plate surface is set to 0.05 to 0.30 mm is that if the entrance side plate surface is less than 0.05 m, the amount of oil drawn into the roll pipe increases as the rolling speed increases, and oil pits are formed. If the frequency of occurrence is high and Ra on the inlet side plate surface is more than 0.30 m, oil will flow from the concave side of the plate surface in the circumferential direction of the roll from the inlet side of the roll pipe to the outlet side, and the amount of oil in the roll pipe Although oil pits can be reduced and the generation of oil pits can be suppressed, on the other hand, the surface roughness cannot be sufficiently repaired with a work roll and the desired gloss cannot be obtained, making it difficult to obtain high gloss in any case. It is because it becomes.
- the center line average roughness of the work roll is Ra: more than 0.03 m to 0.10 m
- the surface roughness on the final pass entry side is defined as center line average roughness Ra: 0.05 m to 0.10 im. Gloss is obtained.
- the average roughness of the roll exceeds 0.03, the surface roughness before finishing can be reduced to 0.05 Aim to 0.10 m. It is considered that the amount of rolling oil confined is reduced, and the amount of oil pits generated due to an increase in oil film thickness is further reduced.
- the center line average roughness of the work roll is as fine as Ra: 0.03 m or less
- the center line average roughness of the final pass entry side plate surface is defined as Ra: 0.10 / _im to 0.30 / _im.
- a better gloss is obtained.
- the average roughness of the roll is as fine as 0.03 / m or less, if the sheet surface roughness before finishing is 0 ⁇ 10 ⁇ ⁇ ⁇ 0.30 ⁇ ⁇ , rolling oil flows out along the polished surface of the sheet, It is considered that the amount of oil pits generated is further reduced.
- the SUS304 stainless steel strip was rolled under the conditions shown in Table 1.
- the same roll tungsten carbide having a Young's modulus of 57,000 kg mm 2 and a center line average roughness Ra of 0.018 111 to 0.09 11 is used as a work roll in the final rolling pass.
- the surface roughness was Ra: 0.10 m and 0.20 m
- the final pass rolling speed was variously changed, and the glossiness (Gs (20 °; ); L direction).
- the same WC roll Young's modulus:
- FIG. 1 is a graph showing the relationship between the glossiness of the examples (A, B, C) and the comparative examples (D, E, F, G) and the final pass rolling speed.
- the final pass rolling speed was 200 mpm or more, and the glossiness was below the lower limit level.Therefore, rolling at a lower speed was forced, and much time was required for rolling. .
- the glossiness exceeding the lower limit was maintained even when the final pass rolling speed was increased to 300 mpm, and it is clear that the production efficiency is significantly improved.
- a cold rolled stainless steel strip having high gloss can be rolled at a higher speed than in the past, so that it has an excellent effect that it can be manufactured with high production efficiency.
