Detailed Description
In order to solve the technical problems that the buckling grade of the strip steel cannot be judged before the strip steel is on line in the prior art, and then an operator cannot be prompted to make corresponding measures, so that the product quality and the production efficiency are reduced, the invention provides a method and a device for determining the buckling grade of the strip steel, wherein the method comprises the following steps: establishing a band steel buckling grade table; before rolling a target strip steel, acquiring the steel type specification of the target strip steel, and determining the group of the target strip steel and the width and thickness of the target strip steel according to the steel type specification; and traversing the buckling grade table, judging whether the group, the width and the thickness of the target strip steel are in the buckling grade table, and if so, determining the buckling grade of the target strip steel according to the group, the width and the thickness of the target strip steel.
The technical solution of the present invention is further described in detail by the accompanying drawings and the specific embodiments.
Example one
The embodiment provides a method for determining buckling grade of strip steel, and as shown in fig. 1, the method comprises the following steps:
s110, pre-establishing a band steel buckling grade table;
in order to determine the buckling grade of the strip steel, a strip steel buckling grade table needs to be established in advance.
As an alternative embodiment, the pre-established band steel buckling grade table includes:
acquiring historical data of a plurality of kinds of strip steel, wherein the historical data comprises: the group, width, thickness and buckling index after rolling of each strip steel; the thickness of each strip steel is 0.45-1 mm, and the width of each strip steel is 1260-2000 mm.
Determining buckling grade according to the buckling index of each strip steel;
mapping the buckling grade with the group, the width and the thickness of the strip steel, and establishing a corresponding relation table between the group, the width and the thickness of the strip steel and the buckling grade, wherein the corresponding relation table is the buckling grade table.
Here, since the history steel grades rolled on the production line include many kinds, each steel grade has different width and thickness, and the corresponding buckling index is also different.
Therefore, mapping can be performed according to the group, width, thickness and buckling grade after rolling of each steel type to obtain a corresponding relation table, which can be shown in table 1:
TABLE 1
It should be noted that table 1 only exemplifies a part of steel grades, and does not list all steel grades.
Here, the group to which each strip steel belongs may be determined according to a specific component, and may also be determined according to performance; for example, if the C content of the steel grades is different, the group of the steel grades can be determined according to the C content. The steel grade group can also be determined according to the quality grade; taking quality grade as an example: for example, the quality grade corresponding to BUCK-1 in the table 1 is used for ultra-deep drawing and ultra-deep drawing; the quality grades corresponding to the BUCK-2 are general use, stamping use, deep drawing use and the like; DEF-BUCK is the default steel set.
S111, before rolling the target strip steel, acquiring the steel type specification of the target strip steel, and determining the group of the target strip steel and the width and thickness of the target strip steel according to the steel type specification;
in actual rolling, when a target strip steel needs to be rolled, before rolling, the steel grade specification of the target strip steel needs to be obtained, and the group of the target strip steel and the width and the thickness of the target strip steel are determined according to the steel grade specification. The thickness of the target strip steel is 0.45-1 mm, and the width of the target strip steel is 1260-2000 mm.
As an alternative example, since the steel grades are grouped according to tension because the steel grade specifications include the target tension, the component content, and the like of the target strip steel, the group to which the target strip steel belongs is determined according to the steel grade specifications, and the method comprises the following steps:
acquiring the target tension of the target strip steel in the steel specification;
and determining the group of the target strip steel according to the target tension.
Likewise, the thickness and width can also be directly obtained in the steel grade specification.
S112, traversing the buckling grade table, judging whether the group, the width and the thickness of the target strip steel are in the buckling grade table, and if so, determining the buckling grade of the target strip steel according to the group, the width and the thickness of the target strip steel.
And after the group, the thickness and the width of the target strip steel are determined, inquiring according to the fact that the group, the thickness and the width of the target strip steel are larger than the buckling grade. In particular, the amount of the solvent to be used,
traversing the buckling grade table, judging whether the group, the width and the thickness of the target strip steel are in the buckling grade table, and if the group, the width and the thickness of the target strip steel are in the buckling grade table, searching the group of the target strip steel in the buckling grade table; after the group of the target strip steel is found, the thickness of the target strip steel is found based on the group; after the thickness of the target strip steel is found, the width of the target strip steel is found based on the thickness; and after the width of the target strip steel is found, determining the corresponding buckling grade based on the width.
Here, if any one of the group, the thickness and the width of the target strip steel cannot be found in the buckling level table, it is determined that the strip steel is not easily buckled.
Here, in order to clearly reflect the buckling level, the buckling level table includes a first buckling level table in which the buckling level is higher than that in the second buckling level table and a second buckling level table. Table 1 above may be considered a second buckling level table, and the first buckling level table may then be represented by Table 2:
TABLE 2
During traversal, the buckling grade in the first buckling grade table is higher than that in the second buckling grade table, so that the first buckling grade table is firstly traversed, and if the group, the thickness and the width of the target strip steel cannot be searched in the first buckling grade table, the second buckling grade table is traversed, and the target strip steel is searched in the second buckling grade table. When the buckling level table includes two, the traversal procedure is implemented as follows:
SELECT max(buck_code2) INTO bbuck_code2
FROM ( SELECT * FROM SP_BUCK_CODE2
WHERE stgr_group = l_stgrgrp_BUCK
AND thickness >= p_coil.thickness
AND width <= p_coil.width
ORDER BY 1,2,3
) WHERE ROWNUM = 1;
SELECT max(buck_code1) INTO bbuck_code1
FROM ( SELECT * FROM SP_BUCK_CODE1
WHERE stgr_group = l_stgrgrp_BUCK
AND thickness >= p_coil.thickness
AND width <= p_coil.width
ORDER BY 1,2,3
) WHERE ROWNUM = 1;
bbuck_code:=bbuck_code2;
if l_stgrgrp_BUCK='.DEF-BUCK'then
bbuck_code:=2;
else
if nvl(bbuck_code2,0) < 2 and nvl(bbuck_code1,0)=1 then
bbuck_code:=1;
else
if nvl(bbuck_code2,0) < 2 and nvl(bbuck_code1,0) <1 then
bbuck_code:=3;
end if;
end if;
end if;
it is understood that, in order to simplify the process, a buckling level table may be set in this embodiment, and then a complete buckling level table may be obtained by combining the first buckling level table and the second buckling level table.
Therefore, before rolling, the buckling grade of the steel grade can be known, and then corresponding measures can be taken in the rolling process to ensure the product quality.
Based on the same inventive concept, the invention also provides a device for determining the buckling grade of the strip steel, and the details are shown in the second embodiment.
Example two
The embodiment provides a device for determining the buckling grade of strip steel, as shown in fig. 2, the device comprises: the device comprises a building unit 21, a determining unit 22 and a traversing unit 23; wherein the content of the first and second substances,
the method is used for establishing a band steel buckling grade table in advance;

mapping the buckling grade with the group, the width and the thickness of the strip steel, and establishing a corresponding relation table between the group, the width and the thickness of the strip steel and the buckling grade, wherein the corresponding relation table is the buckling grade table.
Here, since the history steel grades rolled on the production line include many kinds, each steel grade has different width and thickness, and the corresponding buckling index is also different.
Therefore, mapping can be performed according to the group, width, thickness and buckling grade after rolling of each steel type to obtain a corresponding relation table, which can be shown in table 1:
TABLE 1
It should be noted that table 1 only exemplifies a part of steel grades, and does not list all steel grades.
Here, the group to which each strip steel belongs may be determined according to a specific component, and may also be determined according to performance; for example, if the C content of the steel grades is different, the groups of the steel grades can be determined according to the C content; the group of steel grades can also be determined according to the tension of the steel grades; the steel grade group can also be determined according to the quality grade; taking quality grade as an example: for example, the quality grade corresponding to BUCK-1 in the table 1 is used for ultra-deep drawing and ultra-deep drawing; the quality grades corresponding to the BUCK-2 are general use, stamping use, deep drawing use and the like; DEF-BUCK is the default steel set.
In actual rolling, when a target strip steel needs to be rolled, before rolling, the determining unit 22 is configured to obtain a steel type specification of the target strip steel, and determine a group to which the target strip steel belongs and a width and a thickness of the target strip steel according to the steel type specification; the thickness of the target strip steel is 0.45-1 mm, and the width of the target strip steel is 1260-2000 mm.
As an alternative example, since the steel grades are grouped according to the tension in accordance with the specification of the steel grade, the determination unit 22 determines the group to which the target strip belongs according to the specification of the steel grade, including:
acquiring the target tension of the target strip steel in the steel specification;
and determining the group of the target strip steel according to the target tension.
Likewise, the thickness and width can also be directly obtained in the steel grade specification.
And after the group, the thickness and the width of the target strip steel are determined, inquiring according to the fact that the group, the thickness and the width of the target strip steel are larger than the buckling grade. In particular, the amount of the solvent to be used,
the traversing unit 23 is configured to traverse the buckling level table, determine whether the group, the width, and the thickness of the target strip steel are in the buckling level table, and if so, determine the buckling level of the target strip steel according to the group, the width, and the thickness of the target strip steel.
Specifically, the traversing unit 23 searches the group of the target strip steel in the buckling level table; after the group of the target strip steel is found, the thickness of the target strip steel is found based on the group; after the thickness of the target strip steel is found, the width of the target strip steel is found based on the thickness; and after the width of the target strip steel is found, determining the corresponding buckling grade based on the width.
Here, if any one of the group, the thickness, and the width of the target strip cannot be found in the buckling level table, it is determined that the strip is a non-buckling-prone strip.
Here, in order to clearly reflect the buckling level, the buckling level table includes a first buckling level table in which the buckling level is higher than that in the second buckling level table and a second buckling level table. Table 1 above may be considered a second buckling level table, and the first buckling level table may then be represented by Table 2:
TABLE 2
During traversal, the buckling grade in the first buckling grade table is higher than that in the second buckling grade table, so that the first buckling grade table is firstly traversed, and if the group, the thickness and the width of the target strip steel cannot be searched in the first buckling grade table, the second buckling grade table is traversed, and the target strip steel is searched in the second buckling grade table. When the buckling level table includes two, the traversal procedure is implemented as follows:
SELECT max(buck_code2) INTO bbuck_code2
FROM ( SELECT * FROM SP_BUCK_CODE2
WHERE stgr_group = l_stgrgrp_BUCK
AND thickness >= p_coil.thickness
AND width <= p_coil.width
ORDER BY 1,2,3
) WHERE ROWNUM = 1;
SELECT max(buck_code1) INTO bbuck_code1
FROM ( SELECT * FROM SP_BUCK_CODE1
WHERE stgr_group = l_stgrgrp_BUCK
AND thickness >= p_coil.thickness
AND width <= p_coil.width
ORDER BY 1,2,3
) WHERE ROWNUM = 1;
bbuck_code:=bbuck_code2;
if l_stgrgrp_BUCK='.DEF-BUCK'then
bbuck_code:=2;
else
if nvl(bbuck_code2,0) < 2 and nvl(bbuck_code1,0)=1 then
bbuck_code:=1;
else
if nvl(bbuck_code2,0) < 2 and nvl(bbuck_code1,0) <1 then
bbuck_code:=3;
end if;
end if;
end if;
it is understood that, in order to simplify the process, a buckling level table may be set in this embodiment, and then a complete buckling level table may be obtained by combining the first buckling level table and the second buckling level table.
