| 摘要 |
<p>The invention relates to a process for the production of sintered magnesite, sintered dolomite or the like in which the raw material is size-reduced, pre-calcined in a first heat-treatment stage and then intermediately stored, de-aerated and consolidated, after which it is compacted while still hot and sintered in a second heat-treatment stage. The intermediate storage, de-aeration and consolidation of the pre-calcined material before compaction increases the compaction level and also the density and strength of the pressings obtained.</p> |
