Abstract: The basic mechanism of contracting inter-diameter by heating and pressuring on continuously varing position is described, the deformation mechanism of the cylinder to be repaired and characteristics of the interstructure changing of the cylinder are analysed, and the minimum pressure the most suitable heating power by induce and heating period that deformation need are confirmed, The relative equations between moving rates of the inductor and the workbench of liquid pressure machine and the contraction of the cylinder to be repaired are also found out.

Key words: Contraction, Cylinder, Heating, Inter-diameter, Pressuring, Repairing
