Title
(EN) SINTERING PROCESS
(FR) PROCEDE DE FRITTAGE
Abstract
(EN)
A porous burden is formed of carbonaceous material and powdered or other metallurgical material and comprises wet unfired agglomerates of the metallurgical material and water absorbent particulate polymeric material is included in the burden. The burden is fired from one surface and air is drawn through the burden from the fired surface so as to fire substantially the complete burden and to convert it to a sintered mass, and the sintered mass is broken into lumps of sinter.
(FR)
Une charge poreuse est formée d'un matériau carboné et d'un matériau métallurgique pulvérulent ou sous une autre forme et contient des agglomérats mouillés non cuits du matériau métallurgique, un matériau polymère particulaire absorbant l'eau étant inclus dans la charge. La charge est cuite sur une surface et de l'air est aspiré à travers la charge depuis la surface cuite, de manière à faire cuire pratiquement la charge complète et à la convertir en une masse frittée, cette masse frittée étant cassée en morceaux d'aggloméré.
