Description

Impurity removing mechanism for iron making

Technical Field

The utility model relates to an ironmaking technical field especially relates to an impurity removing mechanism for ironmaking.

Background

The technological process of extracting metal iron from iron-containing mineral mainly includes blast furnace process, direct reduction process, smelting reduction process and plasma process. From the metallurgical point of view, iron making is the reverse of iron rusting and gradual mineralization, and simply, pure iron is reduced from iron-containing compounds. In actual production, pure iron does not exist, iron-carbon alloy is obtained, a blast furnace uses a steel plate as a furnace shell, and a refractory brick lining is built in the shell. The blast furnace body is divided into a furnace throat, a furnace body, a furnace waist, a furnace belly and a furnace hearth 5 from top to bottom. Because of the advantages of good economic index, simple process, large production capacity, high labor production efficiency, low energy consumption and the like of the blast furnace ironmaking technology, the iron produced by the method accounts for the vast majority of the total iron production in the world. In the production of a blast furnace, iron ore, coke, and a flux (limestone) for slag formation are charged from the top of the furnace, and preheated air is blown through tuyeres located along the periphery of the furnace at the lower part of the furnace. Carbon in coke (some blast furnaces also blow auxiliary fuel such as coal dust, heavy oil, natural gas and the like) at high temperature is combusted with oxygen blown into air to generate carbon monoxide and hydrogen, and oxygen in iron ore is removed in the ascending process in the furnaces, so that iron is obtained by reduction. The smelted molten iron is discharged from the iron notch. Unreduced impurities in the iron ore are combined with fluxes such as limestone to generate slag, and the slag is discharged from a slag hole. The generated gas is discharged from the top of the furnace, and is used as fuel for hot blast stoves, heating furnaces, coke ovens, boilers and the like after dust removal. The main product of blast furnace smelting is pig iron, by-product blast furnace slag and blast furnace gas in addition, can separate through blast furnace ironmaking impurity and required iron, and this kind of method trade is general, and traditional ironmaking is directly put into the blast furnace with the ore, does not divide the size, can increase the time of ironmaking consumption like this, and the part can be to carrying out ironmaking again after the ore is broken, but can produce some metal dust during the breakage, and this kind of dust can cause the injury to the human body.
