PRODUCTION OF ABRASION-RESISTANT PRESSED ARTICLES MAINLY CONSISTING OF METAL

摘要

One or more comminuted ferrous or non-ferrous metals, optionally mixed with one or more non-softening carbon-containing substances, are mixed with 10 to 40 wt.% of caking and softening hard coal. The resulting mixture is briquetted at 470 to 530.degree.C. The components of the mixture are pre-heated so that the mixture is at the briquetting temperature, the pre-heating temperature of the hard coal being below its softening point, while the pre-heating temperature of the other components is above briquetting temperature.
