摘要
基于四个基本条件,提出了两种薄带连铸活套的设计方法。采用悬链线理论设计活套,活套的形状比较准确,适用于任何形式的自由活套设计,但是得到的悬链线曲线方程为超越方程,实际应用进候比较复杂;当垂跨比famx/l<1/10时,用抛物线理论代替悬链线也有较高的精度,可以满足工程的要求。
This paper proposes two kinds of methods to design loops of strip casting based on four essential requirements. The first method uses the catenary equation to obtain the equation of loops. It is of high precision and accuracy, and is applicable to design any free loops. But the obtained eatenary curve equation is transcendental equation, and it is very difficult for actual use. When the sag ratio famx/l〈1/10, it is feasible to use parabola equation instead of catenary equation to calculate the simplified equation of loops, This simplified equation of loops is also of high precision and can meet the practical requirements.
