Full pellet smelting technology of blast furnace

The invention relates to a full pellet smelting technology of a blast furnace. According to the specific technology, flux pellets, steel slag and limestone are mixed and are added into the blast furnace from the top of the furnace, coke and minerals are added into the blast furnace in batches, in the smelting process, the coke batch weight and the coal injection amount magnitude are adjusted, through a blast furnace distribution chute, any distribution manner in an annular shape, a fixed point and a sector shape is achieved, a material face shape is controlled, and two airflow modes of the edge and the center are formed; high-temperature hot air with the temperature larger than or equal to 1150 DEG C is pressurized and fed into the blast furnace through a hot air pipeline, and the coke and pulverized coal combustion participates in the redox reaction in the blast furnace; the minerals are subject to indirect and direct reduction reaction in the blast furnace sequentially through a blocky belt, a soft melting
