Description
技术领域 technical field
本发明涉及一种板带冷轧机的轧机轧辊,尤其涉及一种适于工作辊具有非对称曲线辊形的板带冷轧机的支持辊辊形。The invention relates to a rolling mill roll of a strip cold rolling mill, in particular to a roll shape of a backup roll suitable for a strip cold rolling mill whose working rolls have an asymmetric curved roll shape.
背景技术 Background technique
板带材作为钢铁工业最重要的产品之一,在国民经济发展中起着非常重要的作用。目前板带轧制实践表明,无论轧机配备了多么先进的板形控制系统和控制手段,仍然存在部分品种、规格的带钢板形难于控制,以及板形缺陷导致的轧辊服役周期有限的问题。经分析发现此问题的根源是,一定的辊形配置下轧机的板形调控能力有限,以及服役期内轧辊初始辊形因磨损而劣化。因此,对于已投产的轧机,需要重视并发挥支持辊初始辊形的板形调控功能,和减少甚至避免轧辊表面磨损对辊形以及轧机板形调控性能的不良影响,通过支持辊辊形设计不断优化和提高轧机的板形调控性能并且实现在整个服役期内保持这一性能。As one of the most important products of the iron and steel industry, plate and strip play a very important role in the development of the national economy. The current strip rolling practice shows that no matter how advanced the strip shape control system and control means are equipped in the rolling mill, there are still some problems that the strip shape of some varieties and specifications is difficult to control, and the roll service period is limited due to the flatness defect. After analysis, it is found that the root of this problem is the limited ability to control the shape of the rolling mill under a certain roll configuration, and the deterioration of the initial roll shape of the roll due to wear during the service period. Therefore, for the rolling mills that have been put into production, it is necessary to pay attention to and give full play to the shape regulation function of the initial roll shape of the backing roll, and to reduce or even avoid the adverse effects of roll surface wear on the roll shape and the shape control performance of the mill. Optimize and improve the flatness control performance of the rolling mill and achieve this performance throughout the service life.
合理的辊形曲线的设计可以缓解轧辊纵向受力不均现象,减少轧制过程中的磨损或者使其均匀磨损,直接降低成本,同时减少不良产品率,提高优质产品的生产命中率;合理的辊形曲线的设计可以保证最终板材在横向的厚度均匀,使其不平度、同板差和厚度公差达到国家标准、国际标准乃至苛刻的用户标准;合理的辊形曲线可以帮助轧机充分发挥其功能力,拓展产能,并能顺利开发出一些新品种。A reasonable design of the roll shape curve can alleviate the uneven longitudinal force of the roll, reduce the wear during the rolling process or make it wear evenly, directly reduce the cost, reduce the rate of defective products, and improve the production hit rate of high-quality products; reasonable The design of the roll shape curve can ensure that the thickness of the final plate is uniform in the transverse direction, so that the unevenness, the difference between the same plate and the thickness tolerance can meet the national standard, the international standard and even the strict user standard; a reasonable roll shape curve can help the rolling mill to give full play to its functions Force, expand production capacity, and can successfully develop some new varieties.
当支持辊是平辊、工作辊不是平辊(是非对称曲线型的工作辊,如CVC、CVC+、SmartCrown、UPC)时,会引起支持辊的不对称磨损,也就是说支持辊操作侧(WS侧)与驱动侧(DS侧)磨损量明显不同,工作辊直径大的地方辊间接触压力就越大,磨损量大,严重时WS侧与DS侧的直径差达0.8mm左右。由于来料楔形、带钢跑偏等不对称因素的影响,也容易加剧支持辊的不对称磨损。When the backup roll is a flat roll and the work roll is not a flat roll (asymmetrically curved work roll, such as CVC, CVC + , SmartCrown, UPC), it will cause asymmetric wear of the backup roll, that is to say, the operation side of the backup roll ( WS side) and the driving side (DS side) wear amount is obviously different, where the diameter of the work roll is larger, the contact pressure between the rolls is greater, and the wear amount is larger. In severe cases, the diameter difference between the WS side and the DS side is about 0.8mm. Due to the influence of asymmetrical factors such as incoming material wedge shape and strip deviation, it is easy to aggravate the asymmetric wear of the backup roller.
不对称磨损带来的主要问题有:1)带钢板形不对称;2)如果存在闭环反馈控制,压下倾斜设定值不稳定,波动较大;3)支持辊服役到后期时不对称磨损情况严重,支持辊轴线倾斜,造成油膜轴承的锥套与衬套之间倾斜,改变了静压腔的四条节流边缝隙大小及分布,可能降低静动压油膜的承载能力,加剧启动困难和烧损油膜轴承等问题。The main problems caused by asymmetric wear are: 1) the shape of the strip is asymmetric; 2) if there is a closed-loop feedback control, the setting value of the depression inclination is unstable and fluctuates greatly; 3) the back-up roll is asymmetrically worn when it is in service. The situation is serious. The axis of the support roller is tilted, causing the taper sleeve and the bushing of the oil film bearing to tilt, changing the size and distribution of the gaps on the four throttle sides of the static pressure chamber, which may reduce the bearing capacity of the static and dynamic pressure oil film, and aggravate the difficulty of starting and Problems such as burning oil film bearings.
目前关于支持辊辊形、工作辊辊形的研究有很多,但是关于工作辊(指具有非对称曲线辊形的工作辊)应该配什么样的支持辊辊形的研究却不过,相关专利有:中国专利200510024680.1公开了“一种配合连续可变凸度轧机工作辊辊型曲线的支撑辊”,以及中国专利200410008195.0公开了“一种配合轴向移动改变辊缝凸度工作辊的支承辊辊型”。而国内外的连续可变凸度轧机(CVC轧机)有很多套,因此,这类具有非对称曲线辊形的工作辊应该配什么样的支持辊辊形是一个新颖的、需求量大的课题。At present, there are many studies on the roll shape of the backup roll and the roll shape of the work roll, but there is no research on what kind of roll shape of the backup roll should be equipped with the work roll (referring to the work roll with an asymmetric curve roll shape). The relevant patents include: Chinese patent 200510024680.1 discloses "a back-up roll that matches the roll profile curve of the work roll of a continuously variable crown mill", and Chinese patent 200410008195.0 discloses "a back-up roll that cooperates with axial movement to change the roll gap crown of the work roll ". However, there are many sets of continuously variable crown mills (CVC mills) at home and abroad. Therefore, what kind of back-up roll profile should be matched with this type of work roll with asymmetric curve profile is a novel and highly demanded topic. .
发明内容 Contents of the invention
本发明的目的在于提供一种适于非对称曲线辊形工作辊的支持辊辊形,该支持辊辊形在保持轧机板形控制能力的基础上,能够使支持辊使用时对称磨损,从而避免或有效减轻不对称磨损带来的影响。The purpose of the present invention is to provide a back-up roll shape suitable for asymmetrically curved roll-shaped work rolls. On the basis of maintaining the strip shape control ability of the rolling mill, the back-up roll can be worn symmetrically during use, thereby avoiding Or effectively reduce the impact of asymmetric wear.
本发明是这样实现的:一种适于非对称曲线辊形工作辊的支持辊辊形,是由两部分曲线叠加组成,一部分是由偶次多项式函数表达的支持辊辊形曲线,另一部分是工作辊的辊形曲线,所述支持辊辊形曲线表达式为:The present invention is achieved in this way: a back-up roll shape suitable for asymmetric curve roll-shaped work rolls is composed of two parts of curve superposition, one part is the back-up roll roll shape curve expressed by an even-order polynomial function, and the other part is The roll shape curve of the work roll, the expression of the roll shape curve of the backup roll is:
RSWB(x)=a×R1(x)+b×R2(x)R SWB (x)=a×R 1 (x)+b×R 2 (x)
式中,RSWB(x)为适于非对称曲线辊形工作辊的支持辊辊形;In the formula, R SWB (x) is the backup roll shape suitable for the asymmetric curve roll shape work roll;
R1(x)为由偶次多项式函数表达的支持辊辊形曲线:其表达式为:R1(x)=A2x2+A4x4+A6x6+A8x8+…;R 1 (x) is the backup roll profile curve expressed by an even-degree polynomial function: the expression is: R 1 (x) = A 2 x 2 +A 4 x 4 +A 6 x 6 +A 8 x 8 + ...;
R2(x)为工作辊辊形曲线多项式:R2(x)=A1x+A2x2+A3x3+…;R 2 (x) is the polynomial of the roll shape curve of the work roll: R 2 (x) = A 1 x + A 2 x 2 + A 3 x 3 +...;
x为辊身坐标,以辊面中心为零点,x is the coordinates of the roll body, with the center of the roll surface as the zero point,

本发明的支持辊辊形是将工作辊的辊形按一定比例叠加到由偶次多项式函数表达的支持辊辊形曲线上,此时的工作辊窜动为零,生产中当工作辊正负窜动时,工作辊辊形曲线与支持辊辊形曲线错开一定的距离。因为冷轧中除HC轧机外,工作辊窜动量不大,并不会引起支持辊辊形与工作辊辊形的明显错位,所以工作辊正负窜动并不会引起明显的接触压力不均。因此本发明的支持辊磨损后辊形对称,磨损均匀,从而避免或有效减轻不对称磨损带来的影响。The roll shape of the backup roll of the present invention is to superimpose the roll shape of the work roll on the roll shape curve of the backup roll expressed by an even-order polynomial function in a certain proportion. At this time, the movement of the work roll is zero. During the movement, the roll shape curve of the work roll and the roll shape curve of the backup roll are staggered by a certain distance. Because the movement of the work rolls is not large except for the HC rolling mill in cold rolling, it will not cause obvious dislocation between the roll shape of the backup roll and the work roll, so the positive and negative movement of the work rolls will not cause obvious uneven contact pressure . Therefore, after the backup roller of the present invention is worn, the shape of the roller is symmetrical and the wear is uniform, thereby avoiding or effectively reducing the impact of asymmetric wear.

一种适于非对称曲线辊形工作辊的支持辊辊形(简称SWB支持辊),由两部分曲线叠加组成,一部分是由偶次多项式函数表达的支持辊辊形曲线,另一部分是工作辊的辊形曲线;也就是说,SWB支持辊辊形曲线是:上工作辊上辊面辊形乘比例系数后叠加到上支持辊下辊面辊形上,下工作辊下辊面辊形乘同样的比例系数后叠加到下支持辊上辊面辊形上。这里提到的工作辊辊形是指具有非对称曲线形式的工作辊辊形,例如,CVC辊形(三次方多项式,奇函数)、CVC+辊形(五次方多项式或更高次方,奇函数)、SmartCrown辊形(弦函数曲线)。A back-up roll shape suitable for asymmetric curve roll-shaped work rolls (referred to as SWB back-up rolls), which consists of two parts of superimposed curves, one part is the back-up roll shape curve expressed by an even-order polynomial function, and the other part is the work roll That is to say, the roll shape curve of the SWB backup roll is: the roll shape of the upper roll surface of the upper work roll is multiplied by the proportional coefficient, and then superimposed on the roll shape of the lower roll surface of the upper backup roll, and the roll shape of the lower roll surface of the lower work roll is multiplied by The same proportional coefficient is then superimposed on the roll shape of the upper roll surface of the lower support roll. The roll shape of the work roll mentioned here refers to the roll shape of the work roll with an asymmetric curve form, for example, CVC roll shape (polynomial of cubic power, odd function), CVC + roll shape (polynomial of fifth power or higher power, Odd function), SmartCrown roll shape (chord function curve).
所述SWB支持辊辊形曲线表达式为:The expression of the roll shape curve of the SWB support roll is:
RSWB(x)=a×R1(x)+b×R2(x)R SWB (x)=a×R 1 (x)+b×R 2 (x)
式中,RSWB(x)为适于非对称曲线辊形工作辊的支持辊辊形,即SWB支持辊辊形;In the formula, R SWB (x) is the roll shape of the back-up roll suitable for the asymmetric curved roll-shaped work roll, that is, the roll shape of the SWB back-up roll;
R1(x)为由偶次多项式函数表达的支持辊辊形曲线:其表达式为:R1(x)=A2x2+A4x4+A6x6+A8x8+…;R 1 (x) is the backup roll profile curve expressed by an even-degree polynomial function: the expression is: R 1 (x) = A 2 x 2 +A 4 x 4 +A 6 x 6 +A 8 x 8 + ...;
R2(x)为工作辊辊形曲线多项式:R2(x)=A1x+A2x2+A3x3+…;R 2 (x) is the polynomial of the roll shape curve of the work roll: R 2 (x) = A 1 x + A 2 x 2 + A 3 x 3 +...;
x为辊身坐标,以辊面中心为零点,x is the coordinates of the roll body, with the center of the roll surface as the zero point,
a、b为比例系数,a为0.8~1,b为0.3~0.7。a and b are proportional coefficients, a is 0.8-1, and b is 0.3-0.7.
比例系数a、b的取值范围,a为0.8~1,b为0.3~0.7。R1(x)为专用的支持辊辊形曲线,它可以提高轧机辊缝横刚度和弯辊力调控功效,为保持其控制特性,系数a的值应较大,大于0.8,小于等于1;系数b的取值直接影响辊间接触压力的分布,辊间接触压力的分布又会影响支持辊磨损的情况,b值越大,辊间接触压力越均匀,越有利于减轻支持辊的不对称磨损,但b值越大,辊缝横刚度和弯辊力二次调控能下降越明显,从这个角度考虑b值不能太大,因此b值取值为0.3至0.7之间,有利于支持辊均匀磨损,而又不至于明显降低轧机的控制能力。The value ranges of the proportional coefficients a and b, a is 0.8~1, and b is 0.3~0.7. R 1 (x) is a special backup roll profile curve, which can improve the rolling mill roll gap transverse stiffness and roll bending force regulation effect, in order to maintain its control characteristics, the value of the coefficient a should be larger, greater than 0.8, less than or equal to 1; The value of the coefficient b directly affects the distribution of the contact pressure between the rollers, and the distribution of the contact pressure between the rollers will affect the wear of the backup rollers. The larger the value of b, the more uniform the contact pressure between the rollers, which is more conducive to reducing the asymmetry of the backup rollers. wear, but the greater the value of b, the more obvious the decline in the secondary regulation of the roll gap stiffness and bending force. From this point of view, the value of b should not be too large, so the value of b is between 0.3 and 0.7, which is beneficial to supporting the roll. Uniform wear without significantly reducing mill controllability.
本发明的SWB支持辊辊形是将工作辊的辊形按一定比例叠加到由偶次多项式函数表达的支持辊辊形曲线上,此时的工作辊窜动为零,生产中当工作辊正负窜动时,工作辊辊形曲线与支持辊辊形曲线错开一定的距离,不会引起明显的接触压力不均。因此本发明的支持辊磨损后辊形对称,磨损均匀,从而避免或有效减轻不对称磨损带来的影响。The roll shape of the SWB backup roll of the present invention is that the roll shape of the work roll is superimposed on the roll shape curve of the back-up roll expressed by an even-order polynomial function in a certain proportion. At this time, the movement of the work roll is zero. During the negative movement, the roll shape curve of the work roll and the roll shape curve of the backup roll are staggered by a certain distance, which will not cause obvious uneven contact pressure. Therefore, after the backup roller of the present invention is worn, the shape of the roller is symmetrical and the wear is uniform, thereby avoiding or effectively reducing the impact of asymmetric wear.
实施例Example
本发明的适于非对称曲线辊形工作辊的支持辊应用于某企业的1420CVC冷连轧机上,使用在第1机架支持辊。叠加量为50%,a=1,b=0.5。The back-up roll suitable for asymmetric curved roll-shaped work rolls of the present invention is applied to a 1420CVC continuous cold rolling mill of a certain enterprise, and is used in the first stand back-up roll. The superposition amount is 50%, a=1, b=0.5.
辊形的系数如下:The coefficients for the roll shape are as follows:
(1)1420CVC冷连轧机第1机架的支持辊辊形曲线多项式(上支持辊的下辊面):(1) The polynomial of the roll shape curve of the back-up roll in the first stand of the 1420CVC tandem cold rolling mill (the lower roll surface of the upper back-up roll):
R1(x)=4.751e-8x2-7.541e-13x4+3.977e-18x6 -675≤x≤675R 1 (x)=4.751e -8 x 2 -7.541e -13 x 4 +3.977e -18 x 6 -675≤x≤675
(2)CVC工作辊辊形曲线多项式(上工作辊的上辊面):(2) CVC work roll roll shape curve polynomial (upper roll surface of the upper work roll):
R2(x)=-1.468e-4x-4.934e-8x2+6.990e-10x3 -755≤x≤755R 2 (x)=-1.468e -4 x-4.934e -8 x 2 +6.990e -10 x 3 -755≤x≤755
(3)SWB支持辊辊形曲线多项式(上支持辊的下辊面):(3) Roll shape curve polynomial of SWB back-up roll (lower roll surface of upper back-up roll):
RSWB(x)=R1(x)+0.5×R2(x)R SWB (x)=R 1 (x)+0.5×R 2 (x)
=-7.341e-5x+2.284e-8x2+3.495e-10x3-7.541e-13x4+3.977e-18x6 =-7.341e -5 x+2.284e -8 x 2 +3.495e -10 x 3 -7.541e -13 x 4 +3.977e -18 x 6
-675≤x≤675-675≤x≤675
参见图1中R1(x)与R2(x)的辊形曲线图,以及图3中的SWB支持辊辊形曲线图。下辊的SWB辊形按同样的比例叠加,下辊辊形函数与上辊辊形函数沿y轴对称,这是因为,R1(x)自身左右对称且上下辊的辊形相同,上下工作辊的CVC曲线左右对称,因此计算出的SWB支持辊的下辊辊形与上辊辊形左右对称。See the roll profile graph for R 1 (x) and R 2 (x) in Figure 1, and the SWB backup roll profile graph in Figure 3. The SWB roll shape of the lower roll is superimposed in the same proportion, and the roll shape function of the lower roll is symmetrical to that of the upper roll along the y-axis. This is because R 1 (x) itself is left-right symmetrical and the roll shape of the upper and lower rolls is the same. The CVC curve of the roll is left-right symmetrical, so the calculated roll shape of the lower roll and the upper roll of the SWB support roll is left-right symmetrical.
本发明的SWB支持辊与原辊形的辊间接触压力进行比较。因为辊间接触压力分布包含两项内容:辊间接触压力分布的均匀性和辊间接触压力峰值,前者影响轧辊轴向的不均匀磨损,后者影响轧辊的剥落。参见图3,从图中可以看出,采用SWB支持辊后,辊间接触压力的分布更加均匀,辊间接触压力峰值有所下降;因此本发明的SWB支持辊辊形有利于提高轧辊的服役周期,延长轧辊的使用寿命,降低生产成本。The inter-roll contact pressure of the SWB back-up roll of the present invention was compared with that of the original roll shape. Because the contact pressure distribution between the rolls includes two items: the uniformity of the contact pressure distribution between the rolls and the peak value of the contact pressure between the rolls, the former affects the uneven wear of the roll axial direction, and the latter affects the peeling of the roll. Referring to Fig. 3, it can be seen from the figure that after adopting the SWB backing roll, the distribution of the contact pressure between the rolls is more uniform, and the peak value of the contact pressure between the rolls decreases; therefore, the roll shape of the SWB backing roll of the present invention is conducive to improving the service life of the roll cycle, prolong the service life of the roll and reduce the production cost.
生产实践表明,SWB支持辊使用后,支持辊的不对称磨损由0.5mm减小至0.1mm,支持辊服役周期延长了10000吨。The production practice shows that after the SWB backing roll is used, the asymmetric wear of the backing roll is reduced from 0.5mm to 0.1mm, and the service life of the backing roll is extended by 10,000 tons.
本发明的SWB支持辊只要磨辊车间磨削出相应的辊形即可,加工方便,成本低,可以适用于工作辊具有非对称曲线辊形的板带冷轧机,如CVC轧机、SmartCrown等轧机。The SWB support roll of the present invention only needs to grind the corresponding roll shape in the roll workshop, which is convenient to process and low in cost, and can be applied to strip cold rolling mills with asymmetric curved roll shapes, such as CVC rolling mills, SmartCrown, etc. rolling mill.
