摘要：

为提高钢水质量，降低吨钢成本，减少转炉渣的影响，众多钢厂采用转炉滑板挡渣系统。在这套系统中，转炉挡渣滑板是耐材的核心，滑板寿命影响到系统的更换频率、生产节奏等。通过了解和研究现场挡渣滑板粘渣、夹钢等问题，发现内滑板和外滑板的损毁是不同部位和不同状态，分析了转炉挡渣滑板损毁机理。以现有转炉挡渣滑板材质工艺为基础，分别对内滑板进行了工艺改进，对外滑板进行材质开发和工艺改进。现场使用表明，在其他条件不变的情况下，改进的转炉挡渣滑板比原滑板使用次数大幅提高。

Abstract:

In order to improve the quality of molten steel,reduce the cost of per ton steel and reduce the influence of converter slag,many steel plants have adopted the slag stopping system of converter slide plate.In this system,converter slag stopping slide plate is the refractory core,slide plate life affects the system replacement frequency and production rhythm and so on.Through studying the problems of slag sticking and steel clamping on the spot,it is found that the damages of inner and outer slide plates are in different positions and different states.Based on the existing technology of converter slag stopping slide plate,the processes of inner and outer slide plates are both improved,and the material of outer slide plate is developed.The results show that with other conditions remains,the frequency of the new scheme is much higher than that of the original scheme.

Key words: Slide plate, Slag stopping, Inner slide plate, Outer slide plate, Improvment
