Description
Technical field
The invention belongs to technical field of aluminum alloy technology, be specifically related to a kind of cold rolling straight rolling production method printed with PS version aluminium base.
Background technology
The fabrication processing of existing presensitized plate is as follows: the aluminium base → alkali cleaning → washing → acid neutralization → washing → electrolytic etching → washing of 1xxx system → except dirty peak clipping → washing → anodic oxidation → washing → sealing of hole → washing → oven dry → coating → oven dry → scale cut → check → pile up neatly version → packaging.Because the degree of depth of electrolytic etching is limited, in fact presensitized plate only needs that the shallow textura epidermoidea of aluminium base is all even has higher surface quality.
The shallow textura epidermoidea of aluminium base mainly inherits the characteristic of hot rolling microstructure, with the increase of cold deformation, aluminium base work hardening phenomenon is more and more obvious, crystal grain becomes elongated fibr tissue gradually, so, under existing hot rolling technology condition, time cold rolling, heat treatment step must be increased eliminate and slow down the generation of fibr tissue.The general production and processing technology of existing aluminium substrate for printing is: batching-casting-sawing-milling face-hot continuous rolling-cold rolling-cleaning-heat treatment-cold rolling-straightening-packaging.This processing technology hot finishing temperature degree is low, adopts cleaning annealing in increasing in cold-rolled process, mainly there is following several respects risk and drawback:
1) hot continuous rolling speed is low, finishing temperature is low, and emulsion residual on surface probability is large;
2) matting can increase aluminium base surface damage chance;
3) annealing is abnormal may cause coiled material heat treatment insufficient, and after rolling, aluminium base interior tissue is thick, uneven;
4) after annealing, interlayer adhesion and superficial punctate damage increase, and reduce surface quality, the rate that manufactures a finished product of restriction presensitized plate;
5) energy consumption and metal temporary cycle is increased.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of cold rolling straight rolling production method printed with PS version aluminium base, can ensure under the prerequisite that electrolytic tissue striped uniformity is substantially constant, cancel the Technology for Heating Processing in the existing rolling process of aluminium substrate for printing, reduce the energy consumption in cold-rolling process, shorten metal and take the cycle, reduce product surface damage risk.
For achieving the above object, the invention provides following technical scheme:
Print the cold rolling straight rolling production method with PS version aluminium base, its technological process of production is: batching → founding → hot continuous rolling → cold rolling → stretch-bend leveller → cut;
Described hot continuous rolling comprises hot roughing and hot finishing, in described hot roughing operation, at the upper working rolls and lower working rolls outlet side of hot rough rolling mill, Wire brush roller is set, in described hot finishing operation, at the upper working rolls and lower working rolls outlet side of hot finishing mill, nylon brush roll is set, and the finishing temperature of hot finishing is 295 ~ 350 DEG C, finish to gauge thickness is 2.8 ~ 3.1mm; In described cold rolling process, by the blank Direct Rolling that obtains through hot continuous rolling to the design thickness of PS version aluminium base.
Further, in described hot finishing operation, the flow of emulsion is the 3-5% of the emulsion pump metered flow of hot finishing mill, and the expulsion pressure of emulsion is 0.3 ~ 0.6MPa.
Further, in described hot finishing operation, the depended on pressure between the upper working rolls and lower working rolls of hot finishing mill is 500N, and the rotating speed of working roll is 500 ~ 800rpm, and play frequency is 30 times/min.
Beneficial effect of the present invention is:
Aluminium substrate for printing hot continuous rolling is generally 300 ~ 500 DEG C of high temperature rollings, viscosity is large, roll easily produces sticky aluminium, the cold rolling straight rolling production method of printing PS version aluminium base of the present invention, by the upper working rolls and lower working rolls outlet side at roughing mill, Wire brush roller is set, and nylon brush roll is set at the upper working rolls and lower working rolls outlet side of finishing mill, utilize thermal conduction characteristic and the lubrication property of different-thickness oxide-film, roller surface oxide thickness and uniformity thereof are effectively controlled, effectively can control the surface quality of blank;
The minimum recrystallization temperature of aluminium is 0.4 times of its fusing point, and therefore, the finishing temperature of hot finishing directly affects aluminium base interior tissue; Along with the raising of finishing temperature, aluminium base tissue forms recrystal grain gradually by threadiness, and when temperature continues to raise (after more than 350 DEG C), recrystal grain is grown up obviously, and after cold rolling fragmentation, fibr tissue is thicker elongated; Again because the thickness of aluminium substrate for printing is generally 0.22 ~ 0.265mm, hot finishing finish to gauge thickness determines its cold deformation general working rate, and with the increase of cold deformation, aluminium base fibr tissue is elongated, affects electrolysis effectiveness; The cold rolling straight rolling production method of printing PS version aluminium base of the present invention is by a large amount of creative verification experimental verifications, the finishing temperature of hot finishing is set to 295 ~ 350 DEG C, finish to gauge thickness look is 2.8 ~ 3.1mm, through the design thickness that cold rolling Direct Rolling is PS version aluminium base, in follow-up presensitized plate production process, good electrolytic etching effect can be obtained;
The i.e. cold rolling straight rolling production method of printing PS version aluminium base of the present invention, can ensure under the prerequisite that electrolytic tissue striped uniformity is substantially constant, cancel the Technology for Heating Processing in the existing rolling process of aluminium substrate for printing, reduce the energy consumption in cold-rolling process, shorten metal and take the cycle, reduce product surface damage risk.
