Abstract

para melhorar a redutibilidade de minério sinterizado, é revelada uma quasipartícula para sinterização incluindo, pelo menos, matéria prima de minério de ferro, matéria prima à base de calcário e matéria prima à base de combustível, cada sendo usada para produzir minério sinterizado para altos-fornos, em que a matéria prima de minério de ferro forma um núcleo da quasipartícula e a matéria prima à base de calcário e a matéria prima à base de combustível são revestidas na circunferência do núcleo e em que o núcleo formado da matéria prima de minério de ferro contém minério de ferro em geral tendo um teor de metal alcalino menor que 0,05% de massa e minério de ferro com alto teor alcalino tendo um teor de metal alcalino de 0,05% de massa ou mais.to improve the reducibility of sintered ore, a quasiparticle for sintering is revealed including at least iron ore raw material, limestone-based raw material and fuel-based raw material, each being used to produce sintered ore for high- ovens, in which the raw material of iron ore forms a core of the quasiparticle and the raw material based on limestone and the raw material based on fuel are coated on the circumference of the core and in which the core formed from the raw material of ore iron contains iron ore in general having an alkali metal content less than 0.05% by weight and iron ore with high alkaline content having an alkali metal content of 0.05% by weight or more.
