Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
The first embodiment of the present invention provides a method for controlling grain-oriented silicon steel edge waves, as shown in fig. 1, including:
s101, in the process of coiling the strip steel 201 of the oriented silicon steel passing through the decarburization annealing stage, a score line 202 is carved on the lower end side of the strip steel 201, wherein the lower end side is the side of the strip steel 201 contacting with a bearing bottom plate 203 of a high-temperature annealing furnace, and the score line 202 is parallel to the rolling direction of the strip steel 201;
s102, controlling the coiled strip steel 201 to pass through a high-temperature annealing stage and a hot stretching leveling stage and then to reach a finishing stage, and cutting off the rigid edge waves along a score line 202; the edge wave is a portion from the score line 202 to the lower end side of the strip steel 201.
In this embodiment, when the strip 201 of the oriented silicon steel having undergone the decarburization annealing stage is wound, the lower end side of the strip 201 is processed by the score line 202 so that the edge wave generated in the high temperature annealing stage of the strip 201 is cut along the score line 202 in the subsequent process stage. The control method can obviously improve the wave shape of the edge of the oriented silicon steel after high-temperature annealing, effectively reduce the finishing trimming amount, improve the plate shape quality and the yield of the oriented silicon steel and reduce the production cost.
The specific implementation steps of the method for controlling the grain-oriented silicon steel edge wave provided by the embodiment are described in detail with reference to fig. 1:
first, step S101 is executed to cut a score line 202 on the lower end side of the strip 201 in the process of winding the strip 201 of the oriented silicon steel that has passed through the decarburization annealing stage, wherein the lower end side is the side of the strip 201 that contacts the support base 203 of the high temperature annealing furnace, and the score line 202 is parallel to the rolling direction of the strip 201.
Specifically, in the process of winding the strip 201 of the oriented silicon steel that has undergone the decarburization annealing stage, that is, after the strip 201 is discharged from the furnace in the decarburization annealing stage and before the magnesium oxide is applied, the lower end side of the strip 201 is marked with the score line 202, and the strip 201 marked with the score line 202 is wound into a steel coil by the winding machine. The strip 201 is formed into a coil and then transported to a high-temperature annealing furnace in a high-temperature annealing stage. At this time, the steel coil needs to be erected and placed on the supporting bottom plate 203 of the high temperature annealing furnace so that the strip steel 201 enters the high temperature annealing stage. As shown in fig. 2, the lower end side of the upper score line 202 refers to a side of the strip 201 which contacts the support base 203 of the high temperature annealing furnace.
When the lower end side is scored with the score line 202, the following requirements are required to be satisfied, including:
first, a score line 202 is cut on the lower end side within the score length of the strip steel 201, wherein the score line 202 is provided at the tail of the strip steel 201, and the score length is not less than one tenth of the length of the strip steel 201.
Specifically, a score line 202 is cut on the lower end side within the score length of the strip steel 201, wherein the score length indicates that the score line 202 is located at the tail of the strip steel 201, and the length of the score line 202 is at least one tenth of the length of the strip steel 201. For example, the total length of the strip 201 is 1 km, one tenth of the length of the strip 201 is 100 m, and the length of the notch is at least 100 m from the tail of the strip 201, or 200 m from the tail of the strip 201, or the total length of the strip 201. The nicking length is limited to be at least one tenth of the length of the strip steel 201 calculated from the tail part of the strip steel 201, so that the edge cutting amount in the finishing stage is reduced and the production cost is saved under the condition of ensuring the edge wave control efficiency of the strip steel 201.
Second, the score lines 202 are cut in the edge area of the lower end side, wherein the number of the score lines 202 may be not less than 2. The side portion ranges from 10mm to 50mm from the lower end side, the groove width of the score line 202 ranges from 10 μm to 60 μm, and the groove depth of the score line 202 ranges from 5 μm to 100 μm.
Specifically, the side portion ranges from the side of the lower end side by 10mm to 50mm, as shown in fig. 2 as H range. The scored score line 202 will form a score groove as shown in fig. 3. The groove width of the score line 202 is L as shown in fig. 3, and L ranges from 10 μm to 60 μm. The groove depth of the score line 202 is D as shown in fig. 3, and D ranges from 5 μm to 100 μm. The score line 202 meeting the groove depth and the groove width can be used for the edge wave generated by the strip steel 201 in the subsequent high-temperature annealing stage and the edge cutting in the finishing stage, so that an obvious score line 202 mark is formed, the quality of the finished strip steel 201 cannot be influenced, and the control efficiency of the edge wave of the strip steel 201 is improved.
Specifically, as shown in FIG. 4, RD represents the rolling direction of the strip steel 201, the length of the nicking sub-line segments is a, a is greater than or equal to 10mm, the distance between the nicking sub-line segments is b, and the nicking condition is that a/b is greater than or equal to 2. Under the condition, the discontinuous cutting lines 202 can ensure the control efficiency of the edge waves of the strip steel 201, reduce the cutting edge amount in the finishing stage and save the production cost.
It should be further noted that the upper score line 202 is scored at the lower end side by a scoring module, wherein the scoring module includes: a mechanical scoring module, an erosion scoring module, and a laser scoring module. That is, the means for cutting the upper score line 202 is mechanical scoring, etching, laser scoring, etc., and is not limited herein.
Next, step S102 is executed to control the rolled strip steel 201 to pass through the high-temperature annealing stage and the hot stretching leveling stage and then to the finishing stage, and cut off the edge wave of the strip steel along the score line 202; the edge wave is a portion from the score line 202 to the lower end side of the strip steel 201.
Specifically, after the strip steel 201 on which the score line 202 is cut is wound into a steel coil, a high temperature annealing stage is required, and in the high temperature annealing stage, a lower end side of the strip steel 201 may generate a bead, and a fine grain strip may be formed at the score line 202. After the high temperature annealing stage, the strip 201 is subjected to a hot stretch leveling stage, followed by an insulation coating and drying process, and then the strip 201 is subjected to a finishing stage. In the finishing stage, the lower end side of the strip 201 is cut off along the score line 202. If there are a plurality of score lines 202 on the lower end side, the edge wave of the strip steel 201 is cut along a target score line, which is the score line 202 farthest from the edge of the lower end side. Of course, according to the actual situation, one of the plurality of score lines may be selected, and the edge wave of the strip steel 201 may be cut along the score line.
In this embodiment, the edge waves of the strip steel 201 are cut along the score line 202, so that the trimming amount in the finishing stage is reduced, the production cost is saved, and the yield of the oriented silicon steel is improved.
Finally, the cut strip 201 is packaged into a finished product.
The principle of the embodiment is explained as follows:
in the high-temperature annealing stage of the oriented silicon steel, due to the self weight of the steel coil and the different thermal expansion coefficients of the strip steel 201 and the bearing bottom plate 203, the expansion amount and the contraction amount of the strip steel 201 and the bearing bottom plate 203 are different in the temperature rising and reducing process, so that the strip steel 201 and the bearing bottom plate 203 generate edge waves due to friction. After the strip steel 201 is subjected to the high-temperature annealing stage, a fine crystal band is generated at the position of the score line 202 on the lower end side of the strip steel 201, the existence of the fine crystal band can prevent the abnormal growth of edge crystal grains, the plasticity of the strip steel 201 at the position is obviously improved, the generation of the wave shape on the lower end side of the strip steel 201 is prevented, and the larger wave shape is controlled below the score line 202, as shown in fig. 5. In fig. 5, the left side of the graph shows the effect of the absence of score line 202, and the right side of the graph shows the effect of the presence of score line 202. Thus, the presence of score line 202 reduces the amount of finish trim.
In order to show the effect of the control method of the embodiment more clearly and intuitively, some experimental data are provided as follows:
in test groups 1 to 6, the control method of the embodiment is adopted for manufacturing, specifically, the mechanical rolling mode is adopted for decarburization and annealing of the oriented silicon steel, then edge scoring is performed, the parting agent is coated after scoring, and the parameters of the edge scoring are shown in table 1:
table 1: process parameters realized by adopting control method of embodiment
The comparison group adopts 5 comparison groups, wherein in the comparison group 1, edge scoring treatment is not carried out on the oriented silicon steel; in comparative groups 2 to 5, edge scoring treatment was performed on oriented silicon steel, and the specific process parameters of the comparative examples are shown in table 2:
the oriented silicon steel sheets obtained in the experimental group and the comparative group were subjected to high-temperature annealing and stretch leveling, and then the sheet shapes were evaluated, and the comparison results are shown in table 3:
the experimental result shows that the plate shape formed by the control method of the embodiment has higher quality, lower cost and better variable control effect.
One or more technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:
in this example, when the strip of oriented silicon steel having undergone the decarburization annealing stage is wound, the lower end side of the strip is processed to form a score line. The strip steel with the marked line can generate edge waves in the high-temperature annealing stage, and the expansion of the edge waves is limited due to the existence of the marked line. Then, in the finishing stage, the edge waves generated by the strip in the high-temperature annealing stage are cut along the cutting lines. The control method can obviously improve the wave shape of the edge of the oriented silicon steel after high-temperature annealing, effectively reduce the finishing trimming amount, improve the plate shape quality and the yield of the oriented silicon steel and reduce the production cost.
