摘要

在铸造过程中,钢丝的外壳永久受到热机械应力(温度变化、拉拔、弯曲和矫直力、静铁压力)的作用,当这些应力超过外壳的变形能力时,就会导致裂纹的产生。因此,有必要了解在一定的工艺参数(萃取速度、冷却强度等)下,什么样的应力作用在钢壳上,以及钢在高温下的表现。

Experiments Regarding Thermal and Mechanical Deformations of Continuous Cast Steel Wire
During the casting process, the crust of the steel wire is permanently subjected to thermo mechanical stresses (temperature variations, pulling, bending and straightening forces, ferrostatic pressure), which, when exceeding the deformation capacity of the crust, can lead to cracks.Therefore, it is necessary to know what kind of stresses act on the crust and how the steel behaves at high temperatures at certain process parameters (extraction speed, cooling intensity, etc.).
