TUYERE NOZZLE FOR MEASURING THE REMAIN OF FIRE BRICK IN VESSEL

摘要

The present invention relates to a two nozzle (TUYERE NOZZLE) that can measure the residual of the refractory installed in the refining furnace, more specifically to predict the safety residual value of the refractory in the refining furnace for refining molten steel can prevent the accidental leakage of molten steel in advance The present invention relates to a nozzle nozzle for refractory residual measurement in a refinery furnace.;The present invention provides an inner tube 11 to which carbon gas is supplied, an outer tube 2 to which cooling air is supplied to protect the inner tube 11, and an inner tube 11 and 12 fixing the inner tube 11. , The outer tube holder 13, 14, and the inner tube tube 13 connecting the inner and outer holders 13 and 14 to each other to adjust the flow rate of the cooling air supplied to the outer side 11. In the gear nozzle which is connected to the plurality of flow rate and pressure control valves (8) and (9) to adjust the pressure and is installed in the refining furnace (100), the inner tube (11) in the middle of the length of the appearance (12) On the inner circumferential surface of the flow rate sensing tube 4 fixed to the stopper 3 protruding toward the side, a plurality of protrusions 5 are formed to maintain a gap between the inner and outer tubes 11 and 12, The change of the opening degree of the flow regulating valve 8 and the pressure change of the pressure regulating valve 9 generated by the dropping of the sensing tube 4 depend on the signal of the detector. Standing sound an alarm to verify the safety residual value (P) of the refractory material 120, or ear-to-measure for the remaining refractory material to the refining to display messages provides a nozzle.
