由于 BT型布料器具有独特的优点 ,已成功应用于大型高炉上 ,现在有必要在中小型高炉上推广应用。在介绍 BT型布料器结构、原理的基础上 ,针对中、小型高炉的具体情况 ,提出了对 BT型布料器的改进思想 ,并说明了改造后 BT- 型布料器的结构、原理和主要优点。实践证明 ,改造后的 BT- 型布料器更适合中、小型高炉的工艺特点 ,可以在中小型高炉上推广使用 Due to the unique advantages of the BT-type distributor, it has been successfully applied to large-scale blast furnaces. Now it is necessary to popularize and apply it to small and medium-sized blast furnaces. Based on the introduction of the structure and principle of BT type distributor, the idea of ​​improving BT type distributor is put forward according to the specific conditions of middle and small scale blast furnace, and the structure, principle and main advantages of BT-type distributor are illustrated . Practice has proved that the modified BT-type distributor is more suitable for medium and small blast furnace process characteristics, can promote the use of small and medium-sized blast furnace
