摘要

以钢厂100 t钢包为原型

根据相似原理模型与原型1:3.5的比例建立水模型。试验了对应实际吹气量31~237 L/min不同位置单喷嘴和双喷嘴吹气对卷渣情况的影响

发现原吹气孔位置(距钢包中心约0.45R)单喷嘴、距钢包中心0.6R位置单喷嘴、原吹气孔位置(约0.45R)双喷嘴和距中心0.6R位置双喷嘴吹气临界卷渣气量分别为113、93、31、82 L/min

因此实际精炼时软吹采用单喷嘴吹气

合金化阶段用双喷嘴吹气为宜。回归分析得出

单喷嘴吹气时裸露区直径D(/mm)与底吹气量Q/(L·min

Abstract

According to the prototype of a 100 t ladle at steelworks and based on geometric similarity principle

a water model with model and prototype ratio 1:3.5 is established. The effect of different blowing position of single nozzle and double nozzles corresponding real gas blowing rate 31 L/min to 237 L/min on conditions of slag entrapment has been tested. It is found that the critical slag entrapment blowing gas rate for the original blowing position ( about distance from ladle center 0.45R) single nozzle

position distance from center of ladle 0.6R single nozzle

original blowing position ( about 0.45R) double nozzles and position distance from center of ladle 0.6R double nozzles gas blowing is respectively 113

31 and 82 L/min

therefore during real refining process it is available to using single nozzle blowing for soft gas blow

ing and to using double nozzles blowing for alloying stage. By regression analysis the relation formula between diameter of single nozzle blowing exposed areaand bottom gas blowing rate Q/(L

min

-1

) is D =43.333Q +47.5

as 0.6 ＜ Q ＜ 4.6.
