Process Approaches for Producing Complex Composite Inoculants by Rolling of Powder Mixtures. III. Production and Properties of Multi-Component Compacts and Rolled Strips of Powder Inoculants with Different Compositions

The formation of inoculants by pressing and rolling is studied. To obtain process-strong inoculant billets (moldings), optimal routes for the formation of mixtures containing brittle materials that the complex inoculants consist of (up to 60 wt.%) are worked out. It is established that the decrease in the apparent relative density of the powders of ductile components allows decreasing the total content of the latter. The application of large diameter rolls allows obtaining thicker strips, whose strength and density greatly exceeds the required processing strength of the moldings. The increase in the final strip thickness allows increasing the weight of the billet and, therefore, increasing the process efficiency. The powder rolling ensures the production of 5–6 tons of inoculants per month using a 500 mm roller mill.
