Study the Effect of Carbon Content Exist in Midrex Cold Briquetted Sponge Iron on Melting Performance and Comparison with DRI and HBI
, M.Sc. Thesis Sharif University of Technology ; Askari, Masoud (Supervisor)
Abstract
Midrex sponge iron is an active product and there are several problems with store and export it.Cold briquetting sponge iron method is a new method to protect sponge iron from oxidation and provides the possibility of its storage and transportation. Iran as one of the biggest countries that produce sponge iron, has a lot of sponge iron pilots that equipped with cold briquetted machines,but their production capacity is limited and is about 5 percent of their production capacity. With regard to no need for country to these amount of sponge iron, most of these pilots have to store and transport large volumes of sponge iron and the risk of oxidation and fire threatens these units.By using cold...
Experimental and Simulation Study of The Mixing Process of Sponge Iron Particles and Binder
, M.Sc. Thesis Sharif University of Technology ; Molaei Dehkordi, Asghar (Supervisor)
Abstract
Regarding the popularity and progression of iron production with direct reduced method in the world, one of the most common methods of quality maintaining of DRI (Direct Reduced Iron) in transporting and make it globally accessible and used, is to convert it to the briquette form. To increase the quality of briquettes and reduce the use of binder, should make sure that the binder and DRI particles with different sizes are totally mixed together and to prevent segregation of particles with different sizes as much as possible while the binder is spread among the whole particles. Therefore, using the static mixer can be the first choice due to its low production, operational, and maintenance...
