Abstract

"MéTODO DE CARREGAMENTO DE MATERIAL DE ALTO FORNO SEM SINO". A presente invenção refere-se a um método para carregar material em um alto forno sem sino que compreende as etapas de: armazenar coque em pelo menos uma das carvoeiras de topo de forno; armazenar minério em pelo menos uma das carvoeiras de topo de forno; carregar os coques armazenados para o alto forno e ao mesmo tempo girar uma calha do dispositivo de carregamento sem sino e variar um ângulo de inclinação da mesma; e carregar o minério armazenado enquanto gira a calha do dispositivo de carregamento sem sino, e variar o ângulo de inclinação da mesma. A descarga do minério armazenado em pelo menos uma das carvoeiras de topo de forno se inicia quando a quantidade de descarga do coque armazenado em pelo menos uma carvoeira de topo de forno é de 5 a 50 % em massa com relação a uma quantidade de coque de uma batelada. Um material misturado de minério e coque é armazenado em uma das carvoeiras de topo de forno, e o material misturado armazenado na carvoeira de topo de forno é carregado no alto forno enquanto gira a calha de carregamento e modifica um ângulo de inclinação da calha de carregamento."BELLLESS HIGH OVEN MATERIAL LOADING METHOD". The present invention relates to a method for loading material into a bell-free blast furnace comprising the steps of: storing coke in at least one of the furnace top bins; store ore in at least one of the kiln tops; load the stored coke into the blast furnace and at the same time rotate a chute of the bell-free loading device and vary its inclination angle; and loading the stored ore while turning the bell-free loading chute, and varying the tilt angle thereof. Discharge of ore stored in at least one of the furnace coals begins when the amount of coke discharge stored in at least one furnace coals is 5 to 50% by weight with respect to an amount of coke of a batch. A blended ore and coke material is stored in one of the blast furnace bunkers, and the blended material stored in the blast furnace binder is loaded in the blast furnace while rotating the loading chute and modifying a tilt angle of the loading chute. .
