Zusammenfassung:The invention provides a raw gas-aided material forming method, and a material for steel smelting, and relates to the technical field of metallurgy. The method comprises the step that raw gas is led into a mixer containing materials. The raw gas temperature is 650-850 DEG C, and the water content of the materials is larger than or equal to 8 wt%. The materials are dust sludge, or one or two of iron ore concentrate and coal powder. The raw gas is discharged from the mixer after the raw gas is mixed with the materials. After the raw gas is mixed with the materials, the material temperature is increased, while the raw gas temperature is decreased. The materials per ton can be mixed with the raw gas of which the net gas amount is 450-1600 m . The raw gas is mixed with the materials for heatexchange; on one hand, the raw gas temperature can be reduced, and the ammonia amount and energy consumption are reduced during ammonia refrigeration; the material temperature is increased, and facilitates the subsequent formin
