| Abstract: | Using the developed mathematical model for heat transfer in continuous casting, the water distribution of secondary cooling zones for 5 steel grades and 2 section blooms were calculated. According to requirements of metallurgical criteria for bloom solidifying process, conic relation between secondary cooling water flux and casting speed were regressed. The new control model of secondary cooling water was established by taking the superheat of molten steel into account. Moreover, quality of bloom was improved after using new cooling was control model to real production. |
| Keywords: | continuous casting bloom secondary cooling water distribution model automobile steel |
