Title:
SINTERED ORE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/150428
Kind Code:
A1
Abstract:
The purpose of the present invention is to propose a sintered ore manufacturing method that makes it possible to manufacture high strength granulated particles even when using iron ore containing large amounts of fine powder, which is difficult to granulate, and with which high quality sintered ore can be obtained. The manufacturing method is characterized in that a sintering feedstock, which is made from iron ore containing at least 20 mass% of nucleus particles of at least 1 mm grain diameter and containing 10-50 mass% of fine powder with grain diameter of 0.125 mm or less, an aggregating material, and an auxiliary feedstock, is granulated after being stirred using a high speed stirrer, and then fired.
