US3984230A
A combustible bed of ore is formed on a sinter grate, which may form part of a sinter strand. Holes are pierced through the bed before ignition. Combustion-supporting gas is passed through the ignited bed to cause a combustion front to pass through the bed. The bed can be pierced by piercing members carried by a reciprocal frame on a carriage moving parallel to the sinter strand.
