Embodiment 1

[0025] The hot-rolled coil is annealed and pickled at a temperature of 1100 ℃, and the holding time is 1min; the rough rolling reduction rate is 27%, and then the microscopic defects on the surface of the strip are removed by rough grinding. Rolled by work rolls with a roughness of 0.22μm, the finishing rolling reduction rate is 64%; the bright annealing temperature of the finished coil is 1150 ° C, the holding time is 70 seconds, and the speed is reduced by 10% on the basis of conventional annealing TV; the flat elongation is 0.5%.

Embodiment 2

[0027] The hot-rolled coil is annealed and pickled at a temperature of 1080 ℃, and the holding time is 2 minutes; the rough rolling reduction rate is 30%, and then the microscopic defects on the surface of the strip are removed by rough grinding. Rolled by work rolls with a roughness of 0.25μm, the finishing rolling reduction rate is 70%; the bright annealing temperature of the finished coil is 1140℃, the holding time is 1min, and the speed is reduced by 8% on the basis of conventional annealing TV; the flat elongation is 0.6 %.

Embodiment 3

[0029] The hot-rolled coil is annealed and pickled at a temperature of 1120 °C, and the holding time is 5 minutes; the rough rolling reduction rate is 35%, and then the microscopic defects on the surface of the strip are removed by rough grinding. For the second time, a work roll with a roughness of 0.22 μm was used for rolling, and the finishing rolling reduction rate was 80%; the bright annealing temperature of the finished coil was 1150 ° C, the holding time was 100 seconds, and the speed was reduced by 15% on the basis of conventional annealing TV; rate 0.3%.

[0030] T-the English initials of the thickness, V-the maximum process speed of the strip, the product of the two is the TV value, which reflects the annealing ability of the furnace.

Abstract

The invention discloses a stainless steel strip for a water tank, which is characterized in that the mass percentage composition of the stainless steel strip is C: 0.035-0.06%, Si≤0.75%, Mn: 1.0-1.5%, P≤0.040%, S≤0.005% , Cr: 18~20%, Ni: 8.0~10.50%, N≤0.05%, Cu≤0.5%, the rest are Fe and inevitable impurities; the surface roughness of the stainless steel strip is 0.2~0.05μm. By controlling the content of elements such as C, Si, Mn, Cr, and Ni, the stainless steel strip of the invention ensures the elongation performance of the material and avoids cracking during the stamping and stretching process. The surface roughness of the stainless steel strip is 0.05-0.1 μm, The glossiness on the rolling surface at 20° in the rolling direction is 600-700 gu and the glossiness at 20° perpendicular to the rolling direction is 500-600 gu. No surface treatment is required after stamping, which saves production costs and time costs.

Description

technical field [0001] The invention belongs to the technical field of stainless steel, and particularly relates to a stainless steel belt for a sink and a preparation method. Background technique [0002] Stainless steel material is known as one of the important inventions to improve the living standard of human beings in the 21st century. The use of stainless steel material as a sink is natural and unique and has irreplaceable effects with other materials. Stainless steel sinks have been popular for a long time, and many stainless steel sinks are used. This choice is not only because the metallic texture of the stainless steel is quite modern, but more importantly, the stainless steel is easy to clean, the panel is thin and light, and it has corrosion resistance. , high temperature resistance, moisture resistance and so on. The price ranges from a few hundred dollars to several thousand dollars. [0003] As far as the sink market is concerned, there are overall stamping,...
