~
60m/min
。
Utilization due to technique scheme, the present invention compared with prior art has the advantage that the processing method of the hard slim pure copper strips of state of one 1/8th of the present invention, wherein by selecting pure copper strips raw material and being rolling to the finished product thickness size of required 1/8th hard state pure copper strips obtained, first carry out it again making annealing treatment and obtaining the semi-finished product copper strips of soft state, the most above-mentioned semi-finished product copper strips is carried out and hightension rolling, rolling time control controlling rolling tension force just can obtain the hard state of required 1/8th (
H/8
) relatively thin pure copper strips.The production procedure of this processing method is short, and processing cost is low, and the production efficiency of product is high, and the performance of the slim pure copper strips product of acquisition has good stability.
Detailed description of the invention
Below in conjunction with specific embodiment, technical scheme is further elaborated.
Specific embodiment
1
The selection trade mark is
TU2
Pure copper strips as raw material, and be rolling to thickness through four-high reversing mill and be
0.15mm
, width be
380mm
Copper strips, then the pure copper strips after rolling is put in bell type annealing furnace and makes annealing treatment, annealing temperature is
260
DEG C, the heating-up time
2h
And be incubated
3h
, tapping temperature is
60
DEG C, it is thus achieved that soft state (
M
State) semi-finished product copper strips.Forwarding to this semi-finished product copper strips be carried out on cleaning machine row again, use hightension rolling, winding tension is
1400N
, speed is
60m/min
.During rolling, need to observe the flatness situation of copper strip surface, adjust winding tension in time, prevent from causing deformation of strip because winding tension is excessive.The copper strips product of rolling is obtained after rolling.
Specific embodiment
2
With embodiment in this embodiment
1
Difference be, during rolling, the tension force of rolling is
1800N
, after rolling, obtain the copper strips product of rolling.
Above-mentioned two embodiment is produced the copper strips product obtained and carries out performance detection, according to
GB/T228.1
With
GB/T4340.1
Standard test.Respectively to the soft state semi-finished product copper strips after annealing, specific embodiment
