We analyze disadvantages of the available designs of devices aimed at filling the crystallizers with liquid metal and their elements. In order to increase the intensity of mixing of the metal and, hence, to get homogeneous structures of the crystallized metal and guarantee the conditions of safe operation of the personnel, we propose to use an absolutely new design of the device used for the delivery and mixing steel in the crystallizer. The proposed design of a device in the form of a submersible nozzle with reflector placed on a bracket is much simpler and less costly in manufacturing and operation than the well-known complex analog in the form of a deep-flow submersible nozzle with outlet holes.

我们分析了旨在用液态金属及其元素填充结晶器的设备的可用设计的缺点。为了增加金属的混合强度，从而获得结晶金属的均匀结构并保证人员安全操作的条件，我们建议使用全新设计的用于输送和在结晶器中混合钢。与具有出口孔的深流潜水喷嘴形式的众所周知的复杂类似物相比，具有放置在支架上的反射器的潜水喷嘴形式的装置的提议设计在制造和操作上更简单且成本更低。
