Title:
LAYERED COMPOUND HEAT SUPPLY-BASED HEAT-BALANCED SINTERING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/134322
Kind Code:
A1
Abstract:
A layered compound heat supply-based heat-balanced sintering method, which comprises: 1) performing material preparation on an iron-containing raw material, a flux, a solid fuel, and water, and performing material distribution of a prepared sintering mixed material onto a sintering pallet car; 2) igniting the sintering mixed material distributed on the sintering pallet car, and starting to sinter a surface layer of the sintering mixed material located within the sintering pallet car; 3) after ignition, blowing a high temperature gas towards a material surface of the sintering mixed material, the high temperature gas providing heat for an upper-middle layer of the sintering mixed material; 4) after undergoing heat preservation and heat supply, blowing a combustible gas on a material surface of the sintering mixed material, the combustible gas burning within a material layer and supplying heat for a middle layer of the sintering mixed material; 5) after undergoing gas blowing, blowing steam at a material surface of the sintering mixed material, the steam storing heat and supplying heat for a lower layer of the sintering mixed material. By utilizing the present invention, the problem in traditional sintering where there is insufficient heat in an upper material layer and surplus heat in a lower material layer can be effectively solved, and eco-friendly, heat-balanced, low-carbon sintering can be implemented.
