Abstract
PURPOSE: To minimize swinging of a torpedo car and efficiently desulfurize hot in the car by blowing a desulfurizing agent with a carrier gas from a lance whose tip is set to a specific position of the hot iron.
CONSTITUTION: Hot iron is charged from a blast furnace into a torpedo car whose length is 3W10 times as long as the diameter of the central straignt body, and powder CaC2 is blown with a carrier gas such as nitrogen or dry air to desulfurize the hot iron. At this time, the tip of a lance for blowing the desulfurizing agent is set to a position P shifted from the center O of the car by 0.05LW0.25L (L; the length of the car) in the longitudinal direction and by 0.05DW0.25D (D; the width of the car) in the lateral direction, and the blowing is carried out at an angle of 15W90° to the longitudinal direction of the car. Even if 0.5W5wt% slag is present, the CaC2 powder rapidly diffuses to both the ends of the hot iron in the car without entering the slag and quiet rapid desulfurization of high efficiency is facilitated.
