  • System of gas and/or gas and powders injection in liquid metals through rotary refractory lance
    Patent number: 7563405
    Abstract: This invention has the function of injecting gas and/or gas and powders into liquid metals using a refractory lance that is endowed with circular movement around its axis, using low values of pressure and sewage, which provides a better distribution and lower consumption of the powders, resulting in lower cost of the handled metal. The system consists of a refractory lance (7), which is endowed with a rotative junction (6), a motor-reducer (5) and a high-pressure hose (8).
