SUBSTANCE: rocking calcining furnace, for example for expanded clay calcining contains a lined housing installed on bearing rollers with sector cuts, burner units and a drive. The lined housing is mounted using sections formed by two identical subsections. Subsections are made of even number of minimum 4 identical isosceles triangles which are alternately connected along the subsection perimeter with minimum 4 identical equilateral triangles with formation of small and large end face polygonal holes. Meanwhile in the section two subsections are joined to each other by sides of larger end face holes, and the sections are joined to each other along the length of the lined housing by their sides of small end face holes with formation of multiturn screw drum with the mutually directed broken screw lines.
