A thin walled body is deformed in a process in which the body is gripped securely in a holding station and, whilst gripped in the holding station, tooling engages to deform the peripheral wall of the body at a predetermined wall zone.

The tooling is provided at a tooling station which is adjacent the holding station during deformation. The predetermined wall zone is co-aligned with the tooling by rotation of the body about an axis prior to securing at the holding station.

The feasibility of producing graphite gangue wall body materials was discussed by the experiments of four kinds of hardeners solidifying graphite gangue. The result demonstrates that the physical performances of graphite gangue solidified brick samples with 8% hardener D reach the senior grade or the special grade in JC422-91. The study of solidification mechanism indicates that the hardeners produced pastes while being hydrated.

In addition, they can activate the mineral compositions in clay to joint in the reaction to produce pastes and intensive framework.
