REDUCING THE DANGER OF EXPLOSIONS IN THE PRODUCTION OF POWDERS OF IRON AND ITS ALLOYS BY METHODS THAT INVOLVE MECHANICAL COMMINUTION

摘要

A method is described for producing powders, granules, and briquets of chemically active metals and alloys. The method is based on mechanical interlaminar pulverization in an inertial crusher in the presence of a film forming compound. The pulverization process is accompanied by microencapsulation of the powders. The method does not create any danger of explosion. The production operations are waste-free and non-polluting. The microencapsulated powders are less combustible and less explosive than the initial powders. Microencapsulation of the powders keeps dust from being formed during the production process. Results are examined from experimental studies of the combustibility and explosiveness characteristics of powders of iron. ferroalloys, and high-speed steels. This information can be used as the initial data in developing recommendations on explosion-proofing.
