By simulating and optimizing of pouringposition and cylinder variation, the theory of positional autocontrol of distributor boom is presented in this thesis.
Ring pouring channel was set for pouringposition. Ladder-like horizontal gate was designed for horizontal gate. Section area of ingate was calculated by the equation.
