The self-reducing pellets are a mixture of powdered iron ore and reducer. They possess kinetic advantages compared to traditional pellets. One of the disadvantages is the cold low mechanical strength and during thermal processing. In the papermaking industry, there are cellulose residues which are difficult to use in the paper production process. These fibers can reinforce the mechanical strength of the pellets and also serve as an aid in the reduction process. In the experimental part, pellets with 13% of Portland cement (standard sample) and pellets with the same amount of cement but with additions of 1, 2 and 5% dried and milling paper pulp will be produced. A cure time of 30 days in humid environment will be observed. Cold compression tests will be carried out. After heat treatment at 950 A° C falls test, cold and hot abrasion tests were performed. The reduction curves for each of the employed mixtures, as well as analysis by optical and electron microscopy (SEM) will be plotted.
