一、前言为了生产出高质量的连铸坯,我们进行了大量的研究工作。其中之一便是为了控制结晶器的钢水液面,研究了各种钢水液面计。首先在生产中被采用的是放射性同位素液面计,这种液面计是在结晶器外侧设放Co60,通过r射线穿透量的变化来测量钢水的液面高度。但是由于放射线具有危害性,最近大部分已停止使用。接着研制成热电偶式液面计,它是将热电偶埋设在结晶器的壁板内,根据结晶器壁的温度分布情况的变化来检测钢水面的高度。最
First, the foreword In order to produce high quality slab, we conducted a lot of research work. One of them is to control the liquid steel mold surface, studied a variety of molten steel level gauge. The first is used in the production of radioisotope liquid level meter, the liquid meter is placed outside the crystallizer Co60, through the r-ray penetration change to measure the liquid level of molten steel. However, due to the harmful effects of radiation, most of them have been stopped recently. Then developed a thermocouple type liquid level meter, which is embedded in the mold thermocouple wall plate, according to the mold wall temperature distribution to detect changes in the level of the molten steel surface. most
