Sep 08, 2014 · Pelletization Prosess Pelletization is the process of making spheres of high carbon contains uniform quality iron ore. Necessity of pelletization - The configuration of iron ore powder in the blast furnace is more tightly packed and restricts the air flow .For free air flow the powder of iron ore should be in spheres.
HYL Process for Direct Reduction of Iron Ore – IspatGuru
Apr 22, 2017 · HYL process for direct reduction of iron ore was the fruition of research efforts begun by Hojalata y L.mina, S.A. (later known as Hylsa), at the beginning of the 1950s. After the initial evaluation of the concept, it was decided to install a process using a tunnel furnace and several runs were undertaken.
Iron Ore Pelletizing Process: An Overview | IntechOpen
Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the formation of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing.
(PDF) Iron Ore Pelletizing Process: An Overview
The use of binders for iron ore pelletizing is required to: (a) increase the pellet strength before heating – green strength; (b) prevent the collapse of the pellets during firing, when the ...
Direct reduced iron - Wikipedia
Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)). The direct reduction process is comparatively energy efficient. Steelmade using DRI requires significant…
Pellets for Direct Reduction
