Abstract

Изобретение относится к структуре пода печи для плавки во взвешенном состоянии, которая используется в плавильной печи (1), в реакционном пространстве (2), в котором производится плавка сульфидного сырья, содержащего металл, такой как медь, никель или свинец, в присутствии газа, несущего кислород, и формирующего шлак агента для получения металла в форме, предпочтительной для дальнейшей обработки, и где создаваемые расплавленные фазы (5, 6) оседают на под (3) плавильной печи для отделения расплавленных фаз друг от друга, когда температура расплавленных фаз находится в диапазоне 1150-1450°C. В соответствии с изобретением структура пода содержит, по меньшей мере, один изогнутый слой (7) футеровки, наклонный в продольном направлении плавильной печи, так, что температура на поверхности (8), расположенной напротив поверхности, которая входит в контакт с расплавленной фазой, поддерживается ниже 800°C.Международная заявка была опубликована вместе с отчетом о международном поиске.
