blast furnace pelletising

  • Pelletizing an overview ScienceDirect

    Sinter plants are usually located near the blast furnace plant, but pelletizing plants are often located near the mining site Some works have both pelletizing and sintering plants at the smelter sites 113222 Green Pellets The ore is crushed, ground, and concentrated in several steps to very small grain size—eg, over 75% less than 45Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets These are typically fed to a blast furnace or DRI plant as part of the process to make steel Expertise Designed and supplied the largestIron ore pelletizing minevik Outotecbeneficial qualities in the blast furnace operation This report aims to map out the olivine reactions on a micro scale as they descend in the blast furnace The pellets have undergone reactions in an oxidating environment in the pelletising plant and the forsterites have developed a complex set ofOlivine reactions during reduction in blast furnace

  • The Iron Pelletizing Process: Part One Total Materia

    The pelletizing process is a process which contains numerous subprocesses, or process segments On the way from the mine to a final product, the iron ore goes through the following main process segments: 1) The iron ore is crushed and the waste rock is removed About 85 % of the particles should be less than 44 μm (in length, width, or height)ironmaking on largescale using a blast furnace and (2) ironmaking on smalltomid scale using an electric arc furnace (EAF) The raw materials for ironmaking that are charged into a blast furnace include lump ore, sintered ore and pellets The ones charged into an EAF include iron scrap, reduced iron pellets and reduced iron briquettesKOBELCO Pelletizing ProcessBlast furnace slag is a secondary aggregate used widely in construction because of its performance attributes and durability Slag aggregates produced by Tarmac are supplied as CE marked products under the Factory production control process of ISO 9001:2008 for the production of products to BS EN 12342 Aggregates for Unbound and Hydraulically BoundBlast Furnace Slag Tarmac
