MUMBAI, India, June 13 -- Intellectual Property India has published a patent application (202517049135 A) filed by Jfe Steel Corporation, Tokyo, on May 21, for 'method for producing sintered ore.'
Inventor(s) include Iwami Yuji; Fujiwara Shimpei; and Higuchi Takahide.
The application for the patent was published on June 13, under issue no. 24/2025.
According to the abstract released by the Intellectual Property India: "Proposed is a method for producing a sintered ore, in which yield is improved when a carbon material with a low combustion initiation temperature is used in a sintering step. The present invention is a method for producing a sintered ore using a carbon material with a combustion initiation temperature of 550 C or below, wherein a gaseous fuel supplied above a charging layer of a sintering machine is drawn in from below the charging layer, together with air, and introduced into the charging layer. It is preferable that: the gaseous fuel is drawn in, in a direction of advancement of the sintering machine, in a one-half length range on a feed unit side over the charging layer; the carbon material with a combustion initiation temperature of 550 C or below is a non-fossil-fuel organic-based resource and/or a carbon material produced using the non-fossil-fuel organic-based resource as a raw material; the gaseous fuel included in the air introduced into the charging layer has a concentration below the lower limit of concentration for combustion; and when the gaseous fuel is being supplied, the amount of the carbon material is cut back to 10% or less, on a coke-equivalent calorie basis, of the total amount of all of the carbon material when the gaseous fuel is not being supplied."
The patent application was internationally filed on Nov. 09, 2023, under International application No.PCT/JP2023/040407.
