20100047381 | SYSTEM FOR THE PRODUCTION OF ORE WITH GREEN AGGLOMERATES CONTAINING A PROPORTION OF FINES CROSS REFERENCE TO RELATED APPLICATIONS - A plant for the production of ore comprising a proportion of fines, additives and green agglomerates optionally containing a binder, provided with an outer coating consisting of a combustible containing fine-grained carbon, such as coke. In the plant, the ore is mixed with the additives and the optionally available binder. The mixture is pelletized and the green agglomerates thus formed are coated with the combustible, whereby the combustible is introduced into an agglomeration drum. In order to enable continual production of homogeneous-quality green agglomerates, the mixture is pelletized in the agglomeration drum and the combustible is added in an area of the longitudinal extension of the agglomeration drum where the size of the green agglomerates formed in the agglomeration drum is sufficient for further processing. | 02-25-2010 |

20100242684 | PROCESS FOR SINTERING ON A SINTERING MACHINE - A process for sintering metal-containing materials, such as iron ores or manganese ores, on a sintering machine including a sintering belt for transporting the sinter mix during sintering thereof. The sintering belt has first, second and third portions. Sintering waste gas from the third portion is transported to and unified with sintering waste gas from the first portion in a mixing region to form a mixed gas, wherein the transporting distance of the sintering waste gas from the third portion to the mixing region is greater than the transporting distance of the sintering waste gas from the first portion to the mixing region. An apparatus for carrying out the process is disclosed, including the sintering belt, suction boxes operative at the portions of the belt, and lines for conveying the gas produced and the gases used in the process. | 09-30-2010 |
20110179910 | PROCESS FOR PRODUCING AGGLOMERATES OF FINELY PARTICULATE IRON CARRIERS - A process for producing agglomerates from fine-grained iron carriers and at least one binder as a charge material for a metallurgical process is shown. In at least one further agglomeration step, the agglomerates are coated with a layer, comprising iron carriers and at least one binder, and heated in such a way that the binder is cured in the region of the surface of the agglomerates. In a process for producing liquid pig iron or liquid primary steel products from charge materials and possibly additions and agglomerates, the agglomerates are preheated in a reducing zone, which has a preheating stage, in such a way that the agglomerates completely harden in the preheating stage. | 07-28-2011 |
