The invention discloses a machining method of a bi-metal composite roller sleeve. The machining method of the bi-metal composite roller sleeve includes the following steps that (a), an outer steel mold prepared in advance is erected on a centrifugal rotating mechanism, the axis of the outer steel mold is in a horizontal state, a casting nozzle stretches into the outer steel mold from one end of the outer steel mold, the casting nozzle moves in the axial direction in the outer steel mold manipulatively, and the casting nozzle communicates with a casting cup; (b), the centrifugal rotating mechanism is started, the rotating speed of the centrifugal rotating mechanism is set to be 750-1200 r/min, and the centrifugal rotating mechanism drives the outer steel mold to do the rotating movement; and (c), a roller sleeve outer layer of the composite roller sleeve is firstly cast, after the roller sleeve outer layer is cast into the designed thickness, cooling is performed for 3-5 min, then a roller sleeve inner layer of the composite roller sleeve is cast, and casting stops after the roller sleeve inner layer reaches the designed thickness. The invention further discloses the bi-metal composite roller sleeve. Due to the fact that centrifugal casting is adopted, the cast roller sleeve outer layer and the cast roller sleeve inner layer are better in compactness, especially when the rollersleeve inner layer is cast in the second stage, due to the centrifugal force, molten metal of the roller sleeve inner layer is thrown to the roller sleeve outer layer, the proportion and the depth forthe roller sleeve inner layer molten metal to permeate into the roller sleeve outer layer are further improved, and therefore the roller sleeve outer layer and the roller sleeve inner layer are combined better.

The invention provides a method for casting a multi-box hot pot, and belongs to the technical field of iron pot casting.
