Detailed Description
The applicant finds that each procedure of cold rolling production uses strip steel (adjusting material) made of common materials during debugging and recovering processes, the strip steel is scrapped after repeated use for a plurality of times, and a sleeve required in the oriented silicon steel production process can be formed by processing the scrapped strip steel.
In view of this, the embodiment of the application provides a method for manufacturing a sleeve, and the sleeve replaces a sleeve required in the production process of oriented silicon steel by manufacturing the scrap steel into the sleeve, so that the recycling of the scrap steel is realized.
The technical scheme of the embodiment of the application generally comprises the following steps:
a method of making a sleeve comprising: selecting scrap steel with preset size and preset tensile strength; coiling the scrap steel to obtain a target tail coil; controlling a sleeve feeding device on the decarburization annealing line to feed the target tail coil into a coiling machine mandrel in the process that the oriented silicon steel on the decarburization annealing line enters the coiling machine; controlling the coiling machine to coil the oriented silicon steel to obtain a steel coil; and controlling the target tail coil and the steel coil to enter an annular furnace for high-temperature annealing to obtain the sleeve.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
In a first aspect, a method for manufacturing a sleeve according to an embodiment of the present invention, specifically, as shown in fig. 1, includes the following steps S101 to S105.
Step S101, selecting scrap steel with preset size and preset tensile strength.
It is understood that the scrap in the present application may be scrap steel produced by various processes of cold rolling production.
In the specific implementation process, scrapped strip steel is selected, and the strip steel material is preferably non-oriented silicon steel. Specifically, the preset dimensions may include a strip thickness and a strip width, wherein the strip width may be determined according to a width of the decarburized annealed steel coil such that the selected scrap width is similar to the decarburized annealed steel coil width. In one embodiment, scrap steel having a thickness of between 0.5mm and 0.6mm and a width of between 1020mm and 1060mm is selected.
In the specific implementation process, the tensile strength of the selected scrap steel can be determined according to the weight and the occupation rate of the coiled steel coil of the decarburization annealing unit. Preferably, the preset tensile strength is not lower than 700Mpa.
And step S102, coiling the scrap steel to obtain a target tail coil.
Specifically, the scrap steel can be coiled through a recoiling machine set or a splice welding machine set to obtain the target tail coil.
In the specific implementation process, the scrap steel is coiled by a recoiling machine set or a splice welding machine set, and the method can comprise the following steps: acquiring the running length of scrap steel; based on the running length, the coiling speed of the unit is adjusted; and coiling the scrap steel based on the adjusted coiling speed. The winding is a fixed length winding mode.
Specifically, the winding speed of the unit is adjusted based on the running length, which may specifically include: when the running length is equal to the difference value between the set length and the length compensation value, the running speed of the unit is reduced from the first preset speed to the second preset speed; and when the running length is equal to the set length, controlling the machine set to stop.
The set length may be determined based on the thickness of the strip steel and the elevation of the sleeve feeding device of the decarburization annealing unit. In one embodiment, the set length is between 50m and 60m, and the length compensation value may be between 4m and 6 m.
In one embodiment, during coiling of the scrap, the running length of the scrap is recorded by a coiling front steering pinch roll encoder, and when the running length of the scrap, i.e. the coiling length value=set point, -5m, the running speed of the unit is reduced from a first preset speed to a second preset speed, and when the coiling length value=set point, the unit is controlled to stop. The control method can avoid the problem that the difficulty of manually controlling the coiling length is high under the condition of high coiling speed of the steel coil, and the coiling length is too long or too short, so that the expected result cannot be achieved.
Alternatively, the second preset speed may be between 25mpm and 30 mpm.
Of course, as another alternative embodiment, adjusting the winding speed of the unit based on the running length may further include: when the running length is equal to the difference value between the set length and the first length compensation value, the running speed of the unit is reduced from the first preset speed to the second preset speed; when the running length is equal to the difference value between the set length and the second length compensation value, the running speed of the unit is reduced from the second preset speed to a third preset speed; and when the running length is equal to the set length, controlling the machine set to stop. Wherein the first length compensation value may be between 5m and 6m and the second length compensation value between 2m and 3 m.
Further, considering that the thickness of the steel scrap for manufacturing the sleeve is not fixed, in order to avoid the influence of the thickness change of the steel scrap on the coiling precision, when the thickness of the steel scrap is changed, the coiling length of the steel scrap needs to be determined again, and after the coiling length of the steel scrap is determined, the fixed-length coiling mode adjustment can be performed on the unit.
In the specific implementation process, the scrap steel is coiled by a recoiling unit or a splice welding unit, and the method can further comprise the following steps: obtaining the thickness, coiling number of turns and coiling inner diameter value of the scrap steel; determining the outer diameter value of the steel coil according to the thickness, the coiling number and the coiling inner diameter value of the scrap steel; based on the outer diameter value of the steel coil, the coiling speed of the unit is adjusted; and coiling the scrap steel based on the adjusted coiling speed. The coiling is a sizing coiling mode.
In one embodiment, the number of coils and the inner diameter of coils of the scrap can be recorded by a coiler encoder during coiling of the scrap, and the thickness of the strip is a known number. Specifically, according to the thickness, the coiling number of turns and the coiling inner diameter value of the scrap steel, the outer diameter value of the steel coil is determined, which specifically comprises the following steps: and obtaining the steel coil outer diameter value according to the formula of steel coil outer diameter value = 2 times coiling thickness x coiling number + coiling inner diameter value.
Of course, as other alternative embodiments, coiling the scrap steel by the recoiling unit or the splice welding unit may further include: obtaining the thickness of the scrap steel, the initial length of the scrap steel and the coiling inner diameter value; and determining the outer diameter value of the steel coil according to the thickness of the scrap steel, the initial length of the scrap steel and the coiling inner diameter value. The initial length of the scrap steel is the set length.
Specifically, based on the outer diameter value of the steel coil, the coiling speed of the unit is adjusted, which specifically includes: when the outer diameter value of the steel coil is equal to the difference value between the set outer diameter and the outer diameter compensation value, the running speed of the unit is reduced to a second preset speed; when the outer diameter value of the steel coil is equal to the set outer diameter, the machine set is controlled to stop.
The set outer diameter may be controlled according to the size of the sleeve feeding device at the outlet of the decarburization annealing unit. In one embodiment, the outer diameter is set to be between 520mm and 550mm, and the outer diameter compensation value may be between 2mm and 3 mm.
In one embodiment, during coiling of the scrap, the operating speed of the unit is reduced to 30mpm when the coiling outer diameter of the scrap=the set outer diameter 538mm-3mm, and the unit is controlled to stop when the outer diameter value of the steel coil=538 mm. The control method can realize the fixation of the outer diameter of the target tail coil and can also control the stability of the interior of the scrap steel coiling.
Of course, as another alternative embodiment, the adjustment of the winding speed of the unit based on the steel coil outer diameter value may include: when the outer diameter value of the steel coil is equal to the set outer diameter, the machine set is controlled to stop.
In the specific implementation process, a user can adjust the unit according to the field requirement through a fixed-length coiling mode or a sizing coiling mode, coiling of the scrap steel is achieved, and the two control modes can be switched at will.
It can be appreciated that constant tension coiling has certain drawbacks, which are detrimental to the adjustment of tension during coil coiling, and thus, the present application provides a taper coiling mode.
In a specific embodiment, the scrap steel is coiled by a recoiling unit or a welding unit, and the method further comprises the following steps: acquiring the running length of scrap steel; according to the running length, the coiling tension value of the unit is adjusted; and coiling the scrap steel based on the adjusted coiling tension value.
Specifically, adjusting the winding tension value of the unit according to the running length may include: when the running length is equal to a first length threshold value, the coiling tension value of the control unit is increased from the first coiling tension to the second coiling tension until the running length is equal to a second length threshold value, wherein the first length threshold value is smaller than the second length threshold value; when the running length is equal to a second length threshold value, controlling the coiling tension value of the unit to be unchanged until the running length is equal to a third length threshold value, wherein the second length threshold value is smaller than the third length threshold value; when the running length is equal to the third length threshold, the take-up tension value of the control unit is incremented from the second take-up tension to the third take-up tension.
Alternatively, the first length threshold may be between 10m and 20m, the second length threshold may be between 20m and 30m, and the third length threshold may be between 30m and 40m. The first winding tension may be 30KN, the second winding tension may be 35KN, and the third winding tension may be 40KN. As shown in fig. 2, the winding tension graph given in the present application has an abscissa indicating the winding length and an ordinate indicating the winding tension.
In one embodiment, the running length of the scrap is obtained during the coiling of the scrap, and the coiling tension value of the control unit is increased from 30KN to 35KN until the coiling length=20m at the time of coiling length=10m of the scrap. Alternatively, the tension value is increased by one 1KN for every 2m of the winding length.
When the winding length=20m, the winding tension value of the control unit is stabilized at 35KN until the winding length=30m. At winding length=30m, the winding tension value of the control unit is increased from 35KN to 40KN until winding length=40m.
In the specific embodiment, continuous increase or decrease of tension can be realized through interface parameter setting, and the change of the strip steel coiling tightness can be realized through tension adjustment. Compared with a constant tension coiling mode, the coil collapse caused by overlarge tension of the inner coil can be avoided by a control mode that tension is increased firstly and then is unchanged and then increased, the coil loosening and coiling of the outer coil are avoided, and the tower shape of the steel coil is effectively controlled.
In a specific embodiment, after obtaining the target tail roll, the method further includes: and fixing the inner and outer circles of the target tail coil by using a welding machine.
Specifically, as shown in fig. 3, the fixing of the inner and outer coils of the target tail coil using a welder may include: the method comprises the steps of fixing the band tail of a target tail coil by using a strong magnet, unloading the target tail coil by using a coil unloading trolley, hanging the target tail coil onto a tail coil conveying device by using a crown block, fixing the inner and outer rings of the target tail coil by using a welding machine, and taking down the strong magnet. Alternatively, argon arc welding can be used for spot welding and fixing the inner and outer circles of the target tail coil. The loosening and deformation of the target tail coil can be effectively prevented after the welding machine is used for electric welding.
And conveying the target tail coil fixed by the welding machine to a decarburization annealing unit. Further, in order to prevent the sleeve from being bumped against the coiler mandrel during the feeding process, ensure that the sleeve is fed to an accurate position, avoid the process section from slowing down or stopping, and before the sleeve feeding device on the control decarburization annealing line feeds the target tail coil into the coiler mandrel, the method can further comprise the steps of: the inner diameter of the target tail coil is detected by adopting the sleeve inner diameter detection device, so that the inner diameter of the target tail coil meets the use standard, and the target tail coil is tightly combined with the mandrel when the coiling machine expands to the mechanical limit after the target tail coil is fed into the mandrel of the coiling machine.

step S104, controlling the coiling machine to coil the oriented silicon steel to obtain a steel coil;
and step S105, controlling the target tail coil and the steel coil to enter an annular furnace for high-temperature annealing to obtain a sleeve.
