Title: Production of sintered ore
Inventor: NAKANO MASANORI
IPC: C22B1/20
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To improve a production capacity in a low equipped cost by regulating the thickness of pucking layer of a bedding ore charged at the lower part of sintering raw material in a Dweight Lloyd type sintering machine. SOLUTION: The sintering machine is provided with an enlarging width part to a fire grate surface 3 at the lower part of the side wall 4. Then, the thickness 1H of the packing layer 1 of the bedding ore charged at the lower part of the sintering raw material layer 2 is made to 20-25mm. This is the reason to remark that the distribution of blasting into the raw material layer 2 in the enlarging width part having no fire grate surface 1 is promoted from the bedding layer 1, and since the bedding layer 1 is larger grain size in comparison with the raw material layer 2, gas permeability is good and if there is sufficient thickness of the bedding layer 1, the blast is passed into the raw material layer 2 at the enlarging width part through the bedding layer.  In generally, the blasting speed at the end part is lowered by increasing the width enlarging rate ΔW in any bedding layer thickness. However, in the case of exceeding 200mm in the width enlargement, the passing blasting speed can be secured to an almost fixed value. Actually, in the case the thickness 1H is >=20mm, the suitable effect is obtd., but in the case where the thickness exceeds >=50mm, there is a fear to influence to the lowering of sintering yield caused by the thickness of the raw material layer 2.
