Synopsis : In April 1978, Welding Rod and Iron Powder Plant at Chiba Works of Kawasaki Steel Corp. began manufacturing of atomized iron powder for powder metallurgy with a 400t/month capacity as the first stage. Various types of steels melted in the 5t electric furnace are pulverized into iron powder with the water atomizing method developed by Research Laboratories. Exceeding commercial-grade atomized iron powder in purity, compressibility and compatibility, this iron powder is best suited to high density parts for use in powder metallurgy. Special attention is paid to the following points in its industrial use: (1) Manufacture of iron powder of stable quality, (2) Prevention of environmental pollution caused by dust generation and water effluence, (3) Automatization and labor-saving methods centered on transportation of slurry and iron powder, and (4) Prevention of foreign powder mixing. |
