Abstract

MÉTODO PARA PRODUZIR ÁGUA DE PELETIZAÇÃO E MÉTODO PARA PRODUZIR PÉLETES DE MINÉRIO DE FERRO. A presente invenção refere-se a método para produzir água de peletização, o método permitindo facilmente determinar uma porcentagem de mistura de aglutinante polimérico da água de peletização para obter resistência requerida para os péletes brutos. Um aspecto da presente invenção é um método para produzir água de peletização a ser adicionada em uma hora de produção de um produto peletizado, o método incluindo: uma etapa de mistura para misturar um aglutinante polimérico com a água, em que, na etapa de mistura, uma porcentagem de mistura do aglutinante polimérico com respeito à água é determinada de modo que a água de peletização após a mistura satisfaça uma viscosidade alvo. Outro aspecto da presente invenção é um método para produzir péletes de minério de ferro, o método incluindo: uma etapa de adição para adicionar água de peletização para o minério de ferro; uma etapa de peletização para peletizar minério de ferro contendo água de peletização obtido na etapa de adição; e uma etapa de queima para queimar péletes brutos obtidos na etapa de peletização, em que, como a água de peletização, a água de peletização obtida de acordo com o método para produzir água de peletização da presente invenção é usada.METHOD FOR PRODUCING PELLET WATER AND METHOD FOR PRODUCING IRON ORE PELLETS. The present invention relates to a method for producing pelletizing water, the method allowing to easily determine a percentage of polymeric binder mixture of the pelletizing water to obtain required strength for the raw pellets. One aspect of the present invention is a method of producing pelletizing water to be added within one hour of producing a pelletized product, the method including: a mixing step for mixing a polymeric binder with the water, wherein, in the mixing step , a mixing percentage of the polymeric binder with respect to water is determined so that the pelletizing water after mixing satisfies a target viscosity. Another aspect of the present invention is a method for producing iron ore pellets, the method including: an addition step for adding pelletizing water to the iron ore; a pelletizing step for pelletizing iron ore containing pelletizing water obtained in the addition step; and a burning step for burning raw pellets obtained in the pelletizing step, wherein, as the pelletizing water, the pelletizing water obtained according to the method for producing pelletizing water of the present invention is used.
