我们通过炉缸水力学模型试验,对以法国“SAVOIE”为代表的陶瓷杯(保温型)炉缸结构和以美国“UCAR”为代表的热压小炭砖(散热型)炉缸结构在延长炉缸寿命方面的作用进行了比较研究。1 炉缸水力学模型的建立及试验 根据流场几何相似原则,以湘钢3号高炉(1000 m~3)为原型(冶炼工艺条件亦按3 Through the boiler model test of hydraulics, the structure of ceramic cup (Insulation type) hearth represented by “SAVOIE” in France and the hot-pressed small charcoal tile (Radiator type) represented by “UCAR” The role of hearth life in a comparative study. 1 Hearth hydraulic model establishment and test According to the principle of geometric similarity of the flow field, with the No. 3 blast furnace (1000 m ~ 3) as the prototype (smelting process conditions also press 3
