A method for weighing control and transfer of coke used in a blast furnace is provided to improve manufacturing quality and productivity of hot metal by preventing squeezing and rolling phenomena of a belt generated in a belt conveyor, and reduce increase of fuel cost and improve productivity in manufacturing of hot metal by preventing ores from dropping from the belt conveyor. A method for weighing control and transfer of coke used in a blast furnace comprises: a step(S1) of applying discharge instructions to a coke weighing hopper to maintain the weighing hopper as an empty state; a step(S2) of applying a low voltage as an initial starting voltage to a belt conveyor starter of a belt conveyor, thereby starting the belt conveyor at a low speed for a predetermined time so as to measure weight of coke by feeding coke to a weighing hopper from which the whole quantity of coke is discharged; a step(S3) of controlling the belt conveyor starter to allow the belt conveyor starter to slowly reach a rated voltage after a predetermined time; and a step(S4) of applying stopping instructions to the belt conveyor starter when it reaches an approximate value of a ceratin set weighing value, and detecting a speed of the belt conveyor to control voltage of the belt conveyor so that the belt conveyor can be operated at a low speed.
