DEVICE FOR BLOWING GAS INTO A METALLURGICAL VESSEL

摘要

A device for blowing gas into a metallurgical vessel has a gas stopper brick (1) of refractory material with openings (1a, 11) for circulation gas and a gas supply (4) arranged on the bottom plate (3a) of the blowing in device. A safety plate (2, 9) of porous, gas-permeable material is arranged between the gas openings (1, 9, 11) and the gas supply (4) to ensure that no molten metal flows out.
