The invention relates to a method for sintering ferroalloy materials in a continuously operated band sintering process, in which method the pellets to be sintered are arranged on the sintering underlay as an essentially even pellet bed, which pellet bed is conveyed on the sintering underlay through the various steps of the sintering process, and in connection with the sintering process, gas is conducted through the pellet bed. According to the invention, at least the major part of the carbon-bearing material needed for heating the pellet bed up to the sintering temperature is fed onto the surface of ready-made pellets prior to bringing the pellets to the sintering step.
