description A method of switching bottom blown gases and an apparatus suitable for carrying such method into practice in blowing successively in turn a plurality of gases through piping into molten steel in a steel-making furnace through tuyeres or porous plugs for gas blowing located in a lower portion of the steel-making furnace. The method includes the step of directly releasing into atmosphere at least a portion of the gas flowing in and through the piping in response to a rise in the pressure of the gas when switching the blown gases.
