Abstract

본 발명은 전로 정련후 용강을 전로로부터 래들로 출강할시 적용될 수 있는 출강류의 제어방법에 관한 것으로서, 노즐을 통해 적절한 개스 취입조건으로 개스를 출강구내에 취입하므로서, 출강류를 간단하게 제어할 수 있는 전로출강시 출강류의 제어방법을 제공하고자 하는데, 그 목적이 있다.The present invention relates to a method of controlling the tapping flow which can be applied when tapping the molten steel from the converter into the ladle after the refining of the converter, and the tapping flow can be easily controlled by blowing the gas into the tap through proper nozzle blowing conditions through the nozzle. It is to provide a control method of tapping flow when going to the converter, which has its purpose.

본발명은 전로정련후 전로의 출강구를 통해 용강을 전로에서 래들로 출강하는 데 있어서 상기 출강구 둘레에 다수개의 노즐을 설치하고, 용강의 출강개시전에 상기 노즐을 통해 적절한 개스 취입조건즉, 선속도, 압력 및 유량으로 개스를 취입하여 출강구내에서의 출강류를 제어하는 방법을 그요지로 한다.The present invention is to install a plurality of nozzles around the exit in the ladle of the molten steel from the converter to the ladle through the exit of the converter after the refining of the converter, and the appropriate gas blowing conditions through the nozzle before starting the tapping of the molten steel, The idea is to control the flow of tapping in the tapping outlet by blowing the gas at speed, pressure and flow rate.
