PROBLEM TO BE SOLVED: To provide a method for charging raw material into a bell-less blast furnace, for performing the charge of the raw material by swinging a charging chute. SOLUTION: A flowing-adjusted gate arranged in a furnace top bunker is closed at least one in the interval for charging the raw material of one batch. The charging of the raw material in the bell-less blast furnace conventionally divided into two batches can be performed in one-batch with such performance, and the productivity can be improved by simplifying the charging process.
