Sintering in incompletely sealed containers without gas flows

The paper presents an analytical review of published data and the authors’ data on the use of incompletely sealed steel containers for the sintering of iron-powder products in air. Consideration is given to additional techniques for removing oxidation products during sintering such as introduction of protective gas microgenerators into containers or use of a fill. It is concluded that it is reasonable and possible to sinter small and medium batches of powder products and to remelt powder waste at existing thermal stations.
