Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of processing method of SLED structural steel, as shown in Figure 1, which comprises
Step 101: during planisher carries out smooth to strip, being rolled using first with the first roughness range
Roller carries out first stage rolling to strip, wherein the first roughness range is 0.55~0.65um.
Step 102: after rolling in the first stage, the being carried out to strip using the second roll with the second roughness range
Two-stage rolling, wherein the second roughness range is 0.15~0.19um.
In embodiments of the present invention, planisher can be single stand skin pass mill machine, or Two-stand Temper Mill.Wherein,
When planisher is single stand skin pass mill machine, since single stand skin pass mill machine only includes a rack, then, corresponding different rolling sequences make
With different rolls, specifically, first roll to be installed on to the rack of single stand skin pass mill machine in the first stage in the operation of rolling
On, first stage rolling is carried out using first roll, then, after completing first stage rolling, replacement single stand skin pass mill machine
First roll is changed to second roll, second roll is recycled to carry out second stage rolling by the roll in rack.And when flat
When complete machine is Two-stand Temper Mill, since Two-stand Temper Mill includes that two racks, i.e. the first rack and the second rack then will
First roll is mounted in the first rack, and second roll is mounted in the second rack, is rolled using first in the first rack
Roller carries out first stage rolling, then, carries out second stage rolling using the second roll in the second rack.
In embodiments of the present invention, first roll and second roll are smooth roll, the surface of first roll and second roll
Equal chromium plating.When planisher is for roller, either first roll or second roll are equipped with two, and one uses for rolling,
Another is for spare.In addition, the length that the roller phase of planisher is rolled band steel is less than 500km or color difference occurs in strip.
For first 0.55~0.65um of roughness range and second 0.15~0.19um of roughness range, work as first roll
Roughness be 0.63um, when the roughness of second roll is 0.18um, the roughness of finally obtained strip is 0.19um.When
The roughness of first roll is 0.6um, and when the roughness of second roll is 0.17um, the roughness of finally obtained strip is
0.18um.When the roughness of first roll is 0.57um, and the roughness of second roll is 0.16um, finally obtained strip
Roughness is 0.17um.
The present invention was rolled in the first stage by carrying out the rolling in two stages to strip in formation process
It is rolled in journey using the first roll with the first roughness range, using with second in the second stage operation of rolling
The second roll of roughness range is rolled, so as to reduce the roughness of strip.
In the prior art, the factor of limitation SLED bracket manufacture not only includes the roughness of strip, further includes strip
The thickness uniformity of thickness, the strip produced using existing strip processing method is poor, is not able to satisfy manufacture SLED bracket
It is required that the SLED bracket qualification rate produced is low.
In order to overcome the above problem together, in embodiments of the present invention, step 101 includes: using with the first roughness
The first roll of range and the first elongation percentage range rolls the strip progress first stage, wherein the first roughness range is 0.55
~0.65um, the first elongation percentage range are 1.1~1.3%.
Further, step 102 includes: to utilize the second roll pair with the second roughness range and the second elongation percentage range
Strip carry out second stage rolling, wherein the second roughness range be 0.15~0.19um, the second elongation percentage range be 1.1~
1.3%.
In embodiments of the present invention, the total size of elongation percentage is 2.2~2.6%, for the first elongation percentage range 1.1~
1.3% and the second elongation percentage range 1.1~1.3%, the Reducing thickness of the thickness of strip is different under different elongation percentage.In existing skill
In art, there are following corresponding relationship formula for reduction ratio and elongation percentage: λ=ε/(1+ ε), wherein λ is reduction ratio, and ε is elongation percentage.
Further, the difference d' between the exit thickness and inlet thickness of strip can be obtained by following formula: d'=d* λ, wherein d
For the inlet thickness of strip, the thickness Reducing thickness of d' namely strip.Elongation percentage is smaller, then the exit thickness and inlet thickness of strip
Between difference d' it is smaller, in turn, the thickness Reducing thickness of strip is smaller, and the thickness uniformity is better.In the prior art, elongation percentage
Typically greater than 2.8%.In a specific embodiment of the present invention, when the elongation percentage of first roll is prolonging for 1.2%, second roll
Stretch rate be 1.2% when, thus, breaking elongation 2.4%, corresponding, λ1It is 2.3438%, when the inlet thickness of strip is
When 0.49mm, d'1For 0.01148462mm.When the elongation percentage of first roll is 1.15%, the elongation percentage of second roll is 1.2%
When, thus, breaking elongation 2.35%, corresponding, λ2It is 2.2960%, when the inlet thickness of strip is 0.49mm, d'2For
0.0112504mm.When the elongation percentage of first roll is 1.2%, the elongation percentage of second roll is 1.25%, thus, overall elongation
Rate is 2.45%, corresponding, λ2It is 2.3914%, when the inlet thickness of strip is 0.49mm, d'2For 0.01171786mm.
Not only there is the first roll that the present invention is utilized in the operation of rolling in the first stage the first roughness range also to have
There is the first elongation percentage range, meanwhile, the second roll utilized in the second stage operation of rolling not only has the second roughness
Range also has the second elongation percentage range, thus by that can not only reduce the coarse of strip using first roll and second roll
It spends, and the thickness of steel edge portion can also be thinned when being rolled, improve the uniformity of steel strip thickness.
Further, before carrying out first stage rolling, the method also includes:
The execution first stage opens vehicle process.
Further, before carrying out second stage rolling, the method also includes:

Tension be 70Mpa, the bending roller force of the rack of planisher is 200~400KN, the rack two sides of planisher and the spacing of rolling surface
From difference range be 0.1~0.3mm.During second stage opens vehicle, since the vehicle that opens that the first stage opens vehicle process goes out
Mouthful be second stage open vehicle process open vehicle entrance, therefore, during second stage opens vehicle, the tension for opening vehicle entrance is
70Mpa, the tension for opening vehicle outlet is 72Mpa, equally, during second stage opens vehicle, the bending roller force of the rack of planisher
For 200~400KN, the range of the difference of distance is also 0.1~0.3mm between the rack two sides of planisher and rolling surface.
It should be noted that in planisher, for same rack, between the one of side of rack and rolling surface
Distance be first distance, the distance between another side of rack and rolling surface be second distance, first distance and second away from
Difference between, the difference of distance as between the rack two sides and rolling surface of planisher, in the prior art, in general, should
Difference is also referred to as gradient.In an advantageous embodiment, between the rack two sides and rolling surface of planisher distance difference
For 0.1mm.
