一、概述 高炉炉渣是炼铁生产的付产品,过去一直作为废物而扔掉,但近年来这一观念已经改变,特别是水渣已经被广泛地用作制造水泥的原料。 水渣生产时,因为渣量与冷却水流量的比例、熔渣温度等对水渣的质量影响很大,所以对高炉流出的熔融炉渣流量作实时测量以及相应地控制冷却水流量,不仅在提高水渣质量和质量管理上起着重要作用,而且对高炉炉内铁渣管理方面也是一个重要的信息,所以是保证炉况顺行迫切需要解决的课题。 由于测定对象是高温熔融状的炉渣(1450℃～1550℃),粘度大(3.5～4.5泊)、温度一低就凝
I. Overview Blast furnace slag, which is a by-product of ironmaking production, has traditionally been thrown away as waste. However, this concept has changed in recent years. In particular, slag has been widely used as a raw material for the manufacture of cement. In the production of slag, because the ratio of slag volume to cooling water flow rate and slag temperature have a great influence on the quality of the slag, the real-time measurement of the flow rate of the molten slag flowing out of the blast furnace and the corresponding control of the cooling water flow rate not only increase The quality and quality control of the slag plays an important role, and it is also an important message for iron slag management in the blast furnace. Therefore, it is an urgent issue to be solved in order to keep the furnace running smoothly. Since the object to be measured is high-temperature molten slag (1450 ° C to 1550 ° C) and high viscosity (3.5 to 4.5 poises), the temperature is low at a low level
