The blast furnace and direct reduction processes have been the major iron production routes for various iron ores ( goethite, hematite, magnetite, maghemite, siderite, etc.) in the past few decades, but the challenges of maintaining the iron and steelmaking processes are enormous. The challenges, such as cumbersome production routes, scarcity of metallurgical coke, high energy demands ...

Deposit formation in the coalfired rotary kiln is frequently found in the production of fluxed iron ore pellets by the gratekiln process and affects normal production. In this paper, the effects of pellet basicity (CaO/SiO2 mass ratio) on the simulated deposit formation were investigated. The results show that the porosity of deposits samples increases from to % as the pellet ...

During the roasting process of fluxed pellets in a coalfired rotary kiln, the incomplete combustion of pulverized coal injection accelerates deposit formation, which further limits the production efficiency of fluxed pellets. In order to eliminate the above problem, this study investigated the influence of MgO on deposit formation mechanism. The thermodynamic analysis revealed that MgO could ...

At 1250 °C, the proportion of the liquid phases of the bonding phases for fluxed pellets reaches approximately 80% on average, while that of acid pellet deposits is less than 50%. In summary, the increasing CaO in the pellets leads to the formation of the liquid phases more easily, and the increase of CaO could decrease the viscosity of slag ...

A coal agglomerate is produced by the combination of coal fines with a binder obtained by the direct liquefaction of biomass material. The direct liquefaction is carried out in the absence of oxygen at typical temperatures between about 450 and 700° F. and typical pressures between 200 and 3,000 psi, according to known liquefaction processes.
