The paper acquires the equivalent relation between the velocity of wires and annealing temperature through deduction, based on the measurement of the annealing temperature. A controller characterizing annealing temperature could be inserted before the traditional PI annealing controller, so that annealing temperature could be controlled while the annealing temperature deviation is simulated by the error of the velocity of wires. In the paper, a kind of analog circuit is chosen to achieve the equivalent relation between the velocity of wires and annealing temperature by linear fitting under the condition of preciseness.
