在火法冶金过程中的熔融金属及渣液,都具有一定的粘度。为了研究高温熔体结构及高温时各种反应机理,都必须测定其液态时的粘度状况。例如高炉炼铁过程中,炉内尚未还原的氧化物形成初渣一直到炉缸放出终渣,是一个复杂的物理化学变化过程,而炉渣粘度对整个冶炼过程有很重要的影响:(1) 炉料透气性的好坏;(2) 炉缸中渣铁分离和生铁质量;(3) 对于新矿种造渣粘度的了解。欲知它们的粘滞性能,一般是在实验室条件下对试样的粘度进行测定。
In the pyrometallurgical process of molten metal and slag liquid, have a certain viscosity. In order to study the structure of high-temperature melt and various reaction mechanisms at high temperatures, the viscosity conditions of the liquid must be measured. For example, blast furnace ironmaking process, the furnace has not yet reduced the initial formation of oxide slag until the final release of slag into the hearth is a complex physical and chemical changes, and slag viscosity of the entire smelting process has a very important impact: (1) Good or bad charge air permeability; (2) separation of iron and slag in the hearth and pig iron quality; (3) understanding of the new mineral slagging viscosity. To know their viscosity properties, the viscosity of the sample is usually measured under laboratory conditions.
