The invention relates to lime sleeve kilns, in particular to a manufacture method of an inner sleeve of a lime sleeve kiln. The manufacture method comprises the following steps: firstly, previous preparation: compiling manufacture processes and schemes according to drawings, manufacture standards and requirements, setting types of components, such as flanges, so as to determine reasonable plate order sizes, secondly, blanking: determining blanking sizes, milling edges of jointed positions of steel plates through an edge milling machine after multiple flame numerical control cutting is performed, thirdly, barrel rolling: performing head pressing through a special head pressing template, and then performing tube rolling operation through a hoist with a special jig, and fourthly: assembly of the inner sleeve: performing assembly of the lower part of a lower section of the inner sleeve, the assembly of the upper part of the lower section of the inner sleeve, the assembly of the middle section of the inner sleeve and the assembly of the upper section of the inner sleeve, performing welding correction after the assembly of each part, and then performing sand blasting and painting numbers and bearing lines. The method ensures that users can directly know difficulties and certain key control points in manufacture, thereby guaranteeing the manufacture quality of the inner sleeve of the lime sleeve kiln.
