Modeling Sintering Process of Iron Ore Jose Adilson de Castro Graduate Program on Metallurgical Engineering -Federal Fluminense University Brazil 1. Introduction In this chapter, a methodology for simulating th e sintering process of iron ore is presented. In order to study the process parameters and inner phenomena, a mathematical modelDec 18, 2018 Sinter is the primary feed material for making iron in a blast furnace. During the iron ore sintering process in iron and steel manufacturing, sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200 C in a continuous belt-fed furnace. The production of high-quality sinter is crucial for assuring ...

Modeling and Simulation of Iron Ore Sintering Process

Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast furnaces in East Asia. Granulation and thermal densification are two important steps in iron ore sintering and determine the quality of the resultant sinter and the performance of the sintering process.addition to the blast furnace (BF) process, to the sintering of iron ore and iron ore pelletizing are the main areas. The relative high MgO content and SiO 2 content are regarded as beneficial, as well as the relatively low LOI (loss on ignition) of olivine, with respect to dolomite and limestone.

Influence of limestone particle size on iron ore sinter

during sintering process. In present study, effects of iron ore coating layers on coke combustion rate and NOx emission were investigated in a visualize combustion equipment, and an optimized ore blending structure was proposed by sinter pot test. Due to the melting of iron ore coating layers at high tempera-This also pertains to iron sinter, which is constituted of a mixture of raw materials, namely iron ore, fluxes, coke breeze, limestone, lime, dolomite, and return sinter fines, all having various size distributions. Currently Mittal Vanderbijlpark uses Thabazimbi and Sishen iron ore in the production of sinter.
