The specific embodiment
Just as described in the background section, in the prior art, in order to solve the sticking defective of hindering of batching that aluminium alloy strips produces in the operation of rolling, its solution is for reducing rolling speed or increasing the thickness of aluminium alloy strips sea surface oil slick.But reducing rolling speed will certainly influence production efficiency, and the thickness that increases the aluminium alloy strips sea surface oil slick can make production cost increase, and therefore, existing solution is batched sticking scheme of hindering defective and is unfavorable for large-scale promotion and application.
Discover that through the inventor aluminium alloy strips produces in the operation of rolling that to batch the horizontal string that sticking reason of hindering defective is aluminium alloy strips moving, and laterally the moving reason of string be that the frictional force of roll and aluminium alloy strips was less.
On the basis based on above-mentioned research, the embodiment of the invention provides a kind of aluminum alloy strip material rolling method, and this method may further comprise the steps:
The measuring and calculating aluminium alloy strips is laterally gone here and there when moving, the maximum critical friction power between roll and the aluminium alloy strips, i.e. first frictional force;

It more than is the application's core concept, below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
A lot of details have been set forth in the following description so that fully understand the present invention, but the present invention can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization under the situation of intension of the present invention, so the present invention is not subjected to the restriction of following public specific embodiment.
Embodiment one:
Present embodiment provides a kind of aluminum alloy strip material rolling method, and as shown in Figure 3, a kind of schematic flow sheet for this method specifically may further comprise the steps:
Step S301, measuring and calculating aluminium alloy strips laterally go here and there when moving, the maximum critical friction power between roll and the aluminium alloy strips, i.e. first frictional force.
First frictional force can be in actual production process described in this step, measuring and calculating or theoretical calculating are determined by experiment, be that frictional force between roll and the aluminium alloy strips is during less than first frictional force, aluminium alloy strips may take place laterally, and string moves, frictional force between roll and the aluminium alloy strips is during greater than first frictional force, and aluminium alloy strips can not take place that laterally string is moving.
Step S302, when roll aluminum alloy strip steel rolled stock, the frictional force between control roll and the aluminium alloy strips is not less than first frictional force.
In this step, can be by improving the frictional force between roll surface roughness realization control roll and the aluminium alloy strips.Wherein, surface roughness is meant less spacing and the small peak valley unevenness that finished surface has.Distance (pitch of waves) very little (below 1mm) between its two crest or two troughs with the naked eye be nondescript, so it belongs to the microcosmos geometric shape error.Surface roughness is more little, and then the surface is smooth more.
In this step, concrete, can realize the frictional force between control roll and the aluminium alloy strips by the profile arithmetic mean value that improves roll surface roughness.Wherein, profile arithmetic mean value (Ra) is: in the center line direction of roughness curve, sample length is l, and to establish the sampling center line be X-axis, and vertically the multiplying power direction is a Y-axis, with Y=f (x) expression roughness curve, calculate with following formula this moment, and value unit is (μ m), can be referring to shown in Figure 4.In addition, can also represent roll surface roughness with maximum height of the profile, maximum height of the profile (Rz) is: in the center line direction of roughness curve, sample length is l, and to establish the sampling center line be X-axis, and vertically the multiplying power direction is a Y-axis, measures the summit line of roughness curve and the distance between the valley line, this value is maximum height of the profile (μ m), can be referring to shown in Figure 5.
Realize that with the profile arithmetic mean value that improves roll surface roughness the frictional force between control roll and the aluminium alloy strips is example, the profile arithmetic mean value that roll surface roughness can be set is not less than 0.55um, in roll aluminum alloy strip steel rolled stock process, mill speed can guarantee be not less than 700 meters of per minutes, to guarantee production efficiency.
To produce the trade mark is that 3104 aluminium alloy is an example, when mill speed is not less than 700m/min, when roll surface roughness Ra value be 0.4um, occurs batching the sticking defective of hindering easily, according to the statistics of reality in the industrial production as can be known this defective generation probability be about 5%; Constant when other conditions, roll surface roughness Ra value is increased to when being not less than 0.55um, sticking probability of hindering defective occurs batching and drops to about 0.2%.It is remarkable that this way is batched the sticking defective effect of hindering for solution.
The technical scheme that the embodiment of the invention provided, in the aluminium alloy strips operation of rolling, improve the frictional force between roll and the aluminium alloy strips, string moves to have avoided aluminium alloy strips to take place laterally, can make the stress distribution between layer and the layer even, avoid causing stress to concentrate, therefore can reduce or avoid batching the sticking generation of defects of hindering.This scheme compared with prior art, need not to reduce mill speed, also need not to increase the thickness of aluminium alloy strips sea surface oil slick, therefore, production efficiency can not influenced, and do not increase under the prerequisite of production cost, solve and produce the sticking defective of hindering of batching of answering in the aluminium alloy strips operation of rolling, improve the quality of product.
Various piece adopts the mode of going forward one by one to describe in this specification, and what each part stressed all is and the difference of other parts that identical similar part is mutually referring to getting final product between the various piece.To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments.Therefore, the present invention will can not be restricted to embodiment illustrated herein, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
