一、绪言连铸工艺与炼钢工艺的自动化、能节省劳力,节省能源能提高生产率,是近年飞速发展的技术。其中连铸的比例不断提高,但是测量控制部份还存在着需要研究的各种课题。精确测量连铸结晶器里的液面并将其控制在一定的液位上,是提高铸坯质量和达到工艺 I. INTRODUCTION Automation of continuous casting process and steel-making process can save labor, save energy and increase productivity. It is a technology that has developed rapidly in recent years. Among them, the proportion of continuous casting continues to increase, but there are still various topics that need to be studied in the measurement control section. Accurately measure the liquid level in the continuous casting mold and control it at a certain liquid level to improve the quality of the billet and reach the process
