当今连铸机的成功应用可以说是曰于浸入式水口、结晶器振动和熔融保护渣的使用所致。这些技术中结晶器内钢水流动控制技术是提高连铸生产率和铸坯质量的关键,本文就各种流动控制技术进行介绍。1浸入式水口以前,对浸入式水口的吐出角度、浸入深度和内径等基本参数进行了设计,很多试验是通过对吐出孔的孔数和内部形状进行最佳设计后来控制吐出钢水流。这些试验由于水口内氧化铝的粘附,难以维持水口的初期形状,因此得以继续使用的例子很少。但是,随着对钢水
The successful application of today’s continuous casting machines can be said that in the immersion nozzle, the mold vibration and the use of molten flux. Molten steel flow control technology in these technologies is to improve the continuous casting productivity and the key to the quality of billet, this paper describes a variety of flow control technology. Before immersing the nozzle, the basic parameters such as the discharge angle, the depth of immersion and the inner diameter of the immersion nozzle were designed. In many experiments, the discharge flow was controlled by optimizing the number of holes and the internal shape of the discharge hole. There are very few examples of these tests that continue to be used due to the adhesion of alumina in the nozzle and the difficulty of maintaining the initial shape of the nozzle. But with the molten steel
