本文通过实测,研究了同径异步轧制厚度小于1 mm的黄铜带时,单位压力沿纵向的分布规律,并系统地分析了各轧制参数对张直异步轧制和无张力异步轧制单位压力分布的影响。结果表明,异步轧制单位压力分布仍具有峰值;搓轧区占变形区比例x越大,异步轧制的降压效果和摩擦峰的削减作用越大;张直异步轧制厚度小于1 mm的黄铜带时,两辊侧单缸压力分布基本相同,但在无张力异步轧制时,普遍存在两辊则单位压力分布不对称现象。以上问题的研究,对更深入地认识异步轧制的力学特征,完善异步轧制理论具有重要意义。
In this paper, the distribution of unit pressure in the longitudinal direction of the brass strip with the thickness of less than 1 mm on the same diameter was studied by means of field test. The effects of the rolling parameters on the tensile asynchrony rolling and the tensionless asynchrony rolling Influence of unit pressure distribution. The results show that the unit pressure distribution of asynchronous rolling still has the peak value. The larger the proportion x of the deformation zone in the rolling zone, the greater the reduction effect of the anti-rolling effect and the reduction of the friction peak. The thickness of the asynchronization rolling is less than 1 mm Brass belt, the pressure on both sides of the single-cylinder roller pressure distribution is basically the same, but in the case of asynchronous tensionless rolling, there is a common two-roll unit pressure distribution asymmetry. The above problems are of great significance for understanding the mechanical characteristics of asynchronous rolling and perfecting the theory of asynchronous rolling.
