DEVICE FOR MANUFACTURING THE WATER INJECTION OF METAL POWDER CAPABLE OF SUPPRESSING THE BACK FLOW PHENOMENON BY EFFICIENTLY DISCHARGING MOLTEN STEEL DOWNWARDS BECAUSE A CONICAL WATER JET IS CHANGED TO A LAMINAR FORM WHILE SLIDING ALONG THE INSIDE DIAMETER PART PRIOR TO THE COLLISION

摘要

PURPOSE: A device for manufacturing the water injection of metal powder is provided to change each numerous water jet to a conical laminar form, thereby maximally improving the efficiency of the water injection metal powder process.;CONSTITUTION: A device for manufacturing the water injection of metal powder includes a tundish(100), a plurality of water nozzles(200), and a mold member(300). Molten steel(110) is stored in the tundish, and an orifice(120) is mounted on the lower portion of the tundish in order to discharge the molten steel. The water nozzles are mounted based on the jet of dropping molten steel through the orifice of the tundish, and sprays water jet(210) downwards. The mold member includes an inside diameter part(310) and is installed based on the jet of the molten steel to collide the sprayed water jet to the inside diameter part.;COPYRIGHT KIPO 2013
