ABSTRACT

The correct thickness of the shell solidifying within the primary cooling zone of the continuous casting machine is among the most important parameters assuring the safe operation of the casting process. The main problem is related to the fact that the actual measurement of the thickness of steel solidifying in the mould is impossible. Available continuous casting process monitoring systems allow us to calculate its approximate value on the basis of the mould wall temperature reading, and often these systems ensure failure-free steel casting. In this paper, the authors show the results of long-term research carried out when assessing anomalies occurring during the steel continuous casting process. As a result of this research, shell thickness was measured experimentally. On the basis of experimental data, a new model was proposed to describe heat transfer in the primary cooling zone.

摘要

在连铸机的初级冷却区内凝固的壳的正确厚度是确保铸造过程安全运行的最重要参数之一。主要问题是无法实际测量模具中凝固的钢的厚度。可用的连铸过程监控系统使我们能够根据结晶器壁温读数计算其近似值，而且这些系统通常可确保铸钢件无故障。在本文中，作者展示了在评估钢连铸过程中发生的异常时进行的长期研究的结果。作为这项研究的结果，通过实验测量了壳厚度。根据实验数据，
