ABSTRACT:
A chemical machining method and apparatus for forming an internal tpaer in the walls of a sleeve-like body, such as a copper liner of a continuous-casting mold. The body is partially filled with an etching solution, whereby the inside faces of the body are exposed to a pool of the solution. The pool is agitated by blowing air therethrough. By proper control of the rate at which the level of the pool rises or falls within the body, any form of linear or curvilinear taper can be obtained.
