In order to solve the technical problems, the general idea of the embodiment of the application is as follows:

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Example one
Specifically, as shown in fig. 1, the present embodiment provides a method for distributing air cooling volume of high-speed wires, comprising:
and step S101, drawing a loose circle form approximate graph based on the geometric relation of the loose rolls.
In the specific implementation process, the stelmor air cooling line is characterized in that the wire rods are distributed through a coil of a wire laying machine, the coil is scattered and rolled on a transmission roller way to form a spiral line as shown in fig. 2, the air cooling below the transmission roller way cools the coil after being distributed, an air cooling channel below the transmission roller way is shown in fig. 3, and the position angles of two baffle plates inside the air outlet are adjusted according to the coil with different specifications so as to adapt to the nonuniformity of the mass density distribution of the coil.
Step S102, dividing the loose-circle form approximation graph into a plurality of strip areas by using rectangular differentiation, calculating the sizes of the loose rolls in the strip areas, and obtaining the proportion of the sizes of the loose rolls in the strip areas; and obtaining the proportion of the mass of the rolls in the strip area based on the proportion of the sizes of the rolls in the strip area.
In a specific implementation, the loose roll shape approximation map may be imported into a calculation program, and the calculation program may implement the following functions: dividing the loose circle form approximation graph into a plurality of strip areas by using rectangular differentiation, calculating the size of the loose rolls in the strip areas, and obtaining the proportion of the size of the loose rolls in the strip areas; and obtaining the proportion of the mass of the rolls in the strip area based on the proportion of the sizes of the rolls in the strip area.
Specifically, the circle segment pattern approximation map is divided into a plurality of long regions by rectangular differentiation, and as shown in fig. 4, a plurality of (limited or infinite) long regions having the same area are divided horizontally in the width direction of the circle segment approximation map. The size of the unrolling volume (the area of the steel ring or the length of the steel ring) in each strip area can be calculated by double integration:
wherein the upper and lower limits of the integral of x are
And
wherein R is the radius of the inner ring of the steel ring, R is the radius of the outer ring of the steel ring, according to the radius of wires with different specifications, the diameter of the inner ring of the steel ring is the equivalent diameter of the steel ring minus the radius of the wires, and the diameter of the outer ring is the equivalent diameter of the steel ring minus the radius of the wires; the upper and lower limits of the integral of y are the upper and lower limits of the elongated region.
And step S103, distributing the air cooling of the stelmor line based on the proportion of the volume of the unwound rolls in the long strip area.
In the specific implementation process, the wires are stacked on the stelmor line through the laying head, the loose rolls formed by the wires of different specifications after the laying head is looped are different in geometric form, the loop laying mode determines that the lap density gradually transits from dense to sparse from the edge to the middle in the transverse direction, and transverse non-uniformity is generated. In order to ensure the uniformity of the lap in the same turn, the distribution of the air cooling is of great importance, which is directly related to the mass fraction of the various zones of the lap.
Therefore, in this step, the ratio of the mass of the rolls in the long area can be used as a basis for the air-cooling distribution, and the air-cooling distribution in the long area is preferably the same as the ratio of the mass of the rolls in the long area. The air-cooled distribution may also be the same as the tendency of the quality of the top-down roll to change laterally from the doughnut-shaped approximation.
As an alternative embodiment, step S101 further includes:
the uncoiling is equivalent to a plurality of circular steel rings with the same diameter, and the distance between the steel rings is obtained based on the following formula:
wherein, Deltax is the interval of steel rings, u is the roller speed, V is the rolling speed, d1Is the steel ringAn equivalent diameter;
and drawing a scattered circle form approximate graph based on the spacing of the steel rings.
In the specific implementation process, as shown in fig. 4 and 5, the geometric shape of the uncoiled coil formed by the wire passing through the cloth ring of the laying head can be equivalent to a plurality of steel rings with equal intervals, so that the approximate shape graph of the uncoiled coil can be made by knowing the intervals of the steel rings and the equivalent diameter of the steel rings.
The following description will help to explain the method provided by this embodiment by a specific example, which can be successfully applied to stelmor wire cooling, and by taking steel ring specification phi 5.5mm, rolling speed 90m/s and roller speed 1m/s as examples, a form approximation diagram of steel uncoiling is drawn, as shown in fig. 6, the volume ratio can be calculated by using an integration method, i.e. the volume ratio can be calculated, as shown in fig. 7.
As an alternative embodiment, step S101 further includes:
and approximately equating the unrolling to a plurality of circular steel rings with the same diameter, and drawing an approximate unrolling form figure based on the geometric shape of a single steel ring.
In the implementation process, the unrolling roll is approximately equivalent to a plurality of circular steel rings with the same diameter, the size of each circular steel ring is the same, and the air cooling can be distributed based on the mass change trend of the single steel ring schematic diagram of the unrolling roll from top to bottom in the transverse direction.
As an alternative embodiment, the size of the unrolling roll is the unrolling area or the length of the unrolling roll.
As an alternative embodiment, step S102 further includes:
obtaining the size of the loose roll in the strip area based on integral calculation;
obtaining the proportion of the size of the lap in the strip area based on the following formula:
k＝n/m
wherein k is the ratio of the size of the unwound rolls in the strip area, n is the size of the unwound rolls in the strip area, and m is the total size of the unwound rolls.
In the specific implementation process, because the specifications of the steel rings in the same batch are the same, the stacking density distribution of the steel coils of the uncoiled coils can be obtained by calculating the volume ratio of the uncoiled coils in each strip-shaped area (the rigid volume ratio distribution on the same circular cross section is equal to the stacking density distribution of the steel coils), and the distribution of the air volume can be matched through the stacking density distribution of the steel coils.
The following description will help to explain that the method provided by the embodiment can be successfully applied to large-specification stelmor wire cooling control, and by taking the steel ring specification phi of 20mm, the rolling speed of 20m/s and the roller speed of 0.4m/s as examples, a shape approximate graph of steel uncoiling is drawn, as shown in fig. 8, the stacking density distribution of wire rods is matched with the air volume distribution as shown in fig. 9, and by matching the stacking density distribution of wire rods with the air volume distribution, a distribution graph of an air field flow field of a large-specification stelmor wire can be obtained as shown in fig. 10.
