Background technology
All know at the electronic product production field of mobile phone, computer and so on, cold rolled stainless steel band is extensively used to the backboard and the stiffening plate that make the electronic product such as mobile phone, computer.And be used for making the cold rolled stainless steel band of backboard and stiffening plate, not being soft state SUS304 type Stainless Steel Band, is exactly fully hard state SUS304 type Stainless Steel Band.Soft state SUS304 type Stainless Steel Band magnetic flux is low, have good shielding effect, but intensity is poor.Hard state SUS304 Stainless Steel Band intensity is better, but magnetic flux is higher, and shielding effect is poor.Therefore, above-mentioned two kinds of Stainless Steel Bands are used on the electronic product such as mobile phone or computer, or undercapacity, work-ing life of the electronic product such as mobile phone or computer can be shortened, or shielding effect is poor, the health that is unfavorable for the electronic product such as mobile phone or computer user.
Summary of the invention
The problem to be solved in the present invention is to provide a kind ofly produces the method that thickness is 0.05mm Stainless Steel Band.Adopting the thickness produced in this way is the Stainless Steel Band of 0.05mm, can work-ing life of the electronic product such as extending cell phone or computer, is conducive to the health of the electronic product such as mobile phone or computer user.
The problems referred to above that the present invention will solve are realized by following technical scheme:
Production thickness of the present invention is the method characteristic of 0.05mm Stainless Steel Band is comprise the following steps successively:
(1) select materials
Choose the SUS304 type Stainless Steel Band blank that 0.5mm is thick, stand-by;
(2) rolling is carried out
Adopt finishing rolling mill, at 250 ~ 600N/mm
2rolling tensile force, 300m/min roll speed under, become by SUS304 type Stainless Steel Band blank coarse rolling thick for 0.5mm thickness to be the work in-process steel band of 0.11 ~ 0.12mm;
(3) once clean
Above-mentioned work in-process steel band is passed through cleaning by degreasing unit with the speed of 98 ~ 102m/min, when removing a rolling, remains in the grease of reolled steel belt surface;
(4) once anneal
Under pure hydrogen or ammonolysis craft gas shield, be the bright annealing oven of 1100 ~ 1140 DEG C by temperature with the speed of 10 ~ 15m/min by the work in-process steel band through once cleaning;
(5) reroll is carried out
Use finishing rolling mill, at 250 ~ 600N/mm
2rolling tensile force, 300m/min roll speed under, the work in-process steel band through once annealing is rolled into the thick work in-process steel band of 0.053mm;
(6) secondary cleaning is carried out
Work in-process steel band through reroll is passed through cleaning by degreasing unit with the speed of 98 ~ 102m/min, when removing reroll, remains in the grease of reolled steel belt surface;
(7) second annealing is carried out
Under pure hydrogen or ammonolysis craft gas shield, be the bright annealing oven of 1020 ~ 1050 DEG C by temperature with the speed of 6 ~ 7m/min by the work in-process steel band through secondary cleaning;
(8) straightening is carried out
Use 23 roller drawing and straightening machines, carry out large unit elongation aligning to the reolled steel band through second annealing, unit elongation is 3.5 ~ 4.5%, makes the hardness HV of work in-process steel band reach 240 ~ 260;
(9) secondary straightening is carried out
Use 23 roller drawing and straightening machines, reverse straightening is carried out to the reolled steel band through a straightening, obtain that roughness is less than 1.0mm, thickness is the Stainless Steel Band of 0.05mm.
As can be seen from the above scheme; because the present invention utilizes 23 roller drawing and straightening machines; small deformation amount rolling in large unit elongation aligning replacement conventional production methods is carried out to the reolled steel band through second annealing; the hardness HV of work in-process steel band is made to reach 240 ~ 260; hardness is moderate; both met the backboard of the electronic product such as mobile phone or computer, stiffening plate requirement of strength, extended work-ing life of the electronic product such as mobile phone or computer, secondly the lower health that improve shielding effect, be conducive to protecting the electronic product such as mobile phone or computer user of magnetic flux.
