摘　　要：介绍了马鞍山钢铁股份有限公司第四钢轧总厂300t转炉的底吹特点。为了提高转炉底吹的冶金效果,需要对转炉底吹元件位置进行优化选择。通过水模拟试验,并综合考虑顶枪、副枪位置和转炉砌筑状况,确定了转炉透气元件的最佳位置。生产实践证明,其底吹效果良好。This article introduces the characteristics of the bottom blowing system of 300 ton converter of NO. 4 Steel-making ＆ Rolling General Plant of Ma＇anshan Iron ＆ Steel Co. , Ltd.. In order to advance metallurgical effect of bottom blowing system the position of bottom blowing elements has to be optimized. The optimal position of the bottom blow elements is finally determined through water model simulation tests along with a comprehensive consideration of the positions of the top lance and sub-lance positions as well as the construction of the converter. Production practice demonstrates that the bottom blow of those elements is very effective.
