建立了吹氩板坯连铸结晶器大气泡形成机理的物理模型，并考察了操作参数对其的影响。结果表明，大气泡形成有两种机制，(i)喷嘴口出口上端的气泡聚集机制和(ii)漂浮过程中气泡的聚集机制。前者只在一定的水流量大于一定值时才存在，而后者则始终存在。此外，物理模型还给出了抑制大气泡形成的最佳气体流量。
A physical model was established to study the mechanism of large bubble formation in a slab continuous casting mould with argon blowing and the effects of operation parameters on it were investigated. The results show that there are two mechanisms of large bubble formation, (i) the aggregation mechanism of bubbles at the upper tip of the nozzle port exit and (ii) the aggregation mechanism of bubbles during the floating process. The former just exists for a certain water flowrate when the gas flowrate is bigger than a certain value, while the latter always exists. Furthermore, the optimal gas flowrate to restrain the large bubble formation was presented by the physical model.
