Description
Technical field
The present invention relates to a kind of oxygen-free copper bar production two roller triangle milling train of copper strips, production line and production technologies, belong to gold
Belong to manufacture field.
Background technique
The existing relatively advanced method of copper strips of manufacturing is that copper bar is entered to extruder (using big connect product extruder as generation
Table), extruding wheel is rotated under the driving of power by direction, when a copper bar blank enters extruding wheel race, in the friction of sheave
Under power effect, it is introduced in the extrusion chamber of extruding wheel and die cavity formation, since file block prevents moving on for copper material, is rubbing
It wipes and squeezes out copper profile under the high pressure and high temperature action that power generates, since products of different specifications needs different size mold, product rule
Lattice are limited, and mold consumption is big, and qualification rate is low, high production cost.Exist in addition, traditional extruder can not produce thickness
3.5mm copper strips below, such as to produce 3.5mm copper strips below also needs to make copper strips continuation thinning by cold rolling mode, after cold rolling
It again must vacuum annealing.(cold extrusion cost is 400 yuan or so, and vacuum annealing cost is at 300 yuan or so, former material for its production cost
Expect 800 or so, in addition 500 yuan or so of other costs, overall cost is at 2500 yuan or so) (the production of very high and low output
Line overall output per manshift only has 15 tons or so).
And the production technology for not yet occurring that oxygen-free copper bar is made to copper strips of the method for hot rolling at present is retrieved, tradition heat
Roll process is mainly used for the rolling to bulk copper ingot, and specifically being rolled by the way of rolling back and forth repeatedly keeps copper ingot thinning.But this
Kind technique is not particularly suited for the production to thinner thickness copper strips, main reason is that: the rolling effect of traditional two roll surface milling trains
Rate is low, needs to be rolled into copper bar for 5-8 times satisfactory thickness, and the copper bar of small size during the rolling process at a temperature of
Quickly, after generally going through 2 to 3 rollings, temperature is lower than 500 DEG C to drop, just can not continue to roll.Even if can solve temperature
Degree problem, but due to rolling for a long time, copper strip surface will form thicker oxide layer, and the copper strips produced also needs polishing to beat
Mill, also very high and polishing grinding will cause the loss to copper material to production cost.

Referring to shown in Fig. 2, a kind of oxygen-free copper bar of the invention makes copper strips production line, mainly by the milling train 7,2 of heating furnace 6,1
Milling train 8, rinse bath 9 and winder 10 form, and wherein at least No. 2 milling trains 8 utilize two rollers triangle milling train described in embodiment 1.By
It is cylindrical structure in oxygen-free copper bar, positioning is more difficult, and No. 1 milling train 7 generallys use two roll surface milling trains and (refers to two roller surfaces
It is the milling train of plane), orientation problem is such as solved, No. 1 milling train 7 can also directly adopt two roller triangle milling trains.The heating furnace 6,
Rinse bath 9 and 10 structure of winder are well-known technique, and this will not be repeated here.
Further, the production line further includes No. 3 milling trains 11, and No. 3 milling trains 11 are two roll surface milling trains or implementation
Two roller triangle milling train described in example 1.As copper strips be small square when, 7, No. 2 milling trains 8 of No. 1 milling train can be used to be done directly rolling, such as
Copper strips is big square, is further rolled using No. 3 milling trains 11.In addition, such as to produce small copper bar (such as width be 6cm,
With a thickness of 6mm) when, No. 2 milling trains are lifted deactivated, production directly can be completed using No. 1 milling train and No. 3 milling trains.
Embodiment 3:
Referring to shown in Fig. 2 to Fig. 3, a kind of oxygen-free copper bar of the invention makes copper strips production technology, according to life as described in example 2
Producing line realizes that production craft step is as follows:
Step 1: take diameter be 8mm-32mm conventional oxygen-free copper bar be made single layer helical form be put into heating furnace 6 be heated to 700 DEG C-
800 DEG C (being most interpreted as 750 DEG C), the heating furnace is heated using combustion of natural gas, every volume single layer helical form routine oxygen-free copper bar
Length is usually 200 meters or so.
Step 2: by transport mechanism by the conventional oxygen-free copper bar after heating be sent to 7, No. 2 milling trains 8 of No. 1 milling train successively into
Row rolls, and in the operation of rolling, conventional oxygen-free copper bar temperature is kept for 500 DEG C or more, and No. 1 milling train 7 uses two roll surface milling trains
Flat-rolled is carried out to conventional oxygen-free copper bar, conventional oxygen-free copper bar can usually be rolled into the copper bar with a thickness of 5mm-14mm, described No. 2
Milling train 8 carries out three angular rollings to copper bar using two roller triangle milling trains again, can be rolled into the copper strips with a thickness of 1.5mm-3mm.?
Before rolling, lubricating oil is first coated on the roll of 7, No. 2 milling trains 8 of No. 1 milling train, to prevent copper strips and roll adhesion.
Step 3: the copper strips that rolling is completed being sent to rinse bath 9 and carries out high pressure washing, is specifically 8-15%'s using concentration
Alcohol carries out high pressure washing to copper strip surface, is attached to the impurity of copper strip surface to remove (predominantly lubricating oil is because of shape after high temperature
At burning).
Step 4: the copper strips that cleaning is completed is wound by winder 10.
It further, further include No. 3 milling trains 11 in the step 2, No. 3 milling trains 11 are two roll surface milling trains, to biography
