Description

Technical Field

[0001] The utility model relates to the technical field of ironmaking, in particular to an impurity removal mechanism used in an ironmaking process. Background Art

[0002] The process of extracting metallic iron from iron-containing minerals mainly includes blast furnace method, direct reduction method, molten reduction method and plasma method. From the perspective of metallurgy, ironmaking is the reverse behavior of iron rusting and gradual mineralization. Simply put, pure iron is reduced from iron-containing compounds. In actual production, pure iron does not exist, and what is obtained is an iron-carbon alloy. The blast furnace uses steel plates as the furnace shell, and the shell is lined with refractory bricks. The blast furnace body is divided into five parts from top to bottom: throat, furnace body, furnace waist, furnace belly and furnace hearth. Due to the advantages of good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor production efficiency and low energy consumption, it is The iron produced by this method accounts for the vast majority of the world's total iron production. During blast furnace production, iron ore, coke, and slag-making flux are loaded from the top of the furnace, and preheated air is blown in from the tuyere located along the furnace circumference at the bottom of the furnace. At high temperature, the carbon in the coke burns with the oxygen in the blown air to generate carbon monoxide and hydrogen. The oxygen in the iron ore is removed during the rising process in the furnace, thereby reducing the iron. The smelted molten iron is released from the iron mouth, and the unreduced impurities in the iron ore combine with fluxes such as limestone to form slag, which is discharged from the slag mouth. The generated coal gas is discharged from the top of the furnace and, after dust removal, is used as fuel for hot blast stoves, heating furnaces, coke ovens, boilers, etc. Blast furnace smelting

[0003] The main product is pig iron, and there are also by-products blast furnace slag and blast furnace gas. Impurities and the required iron are separated through blast furnace ironmaking. This method is common in the industry. During the ironmaking process, the floating impurities need to be fished out in time. There is still a phenomenon of manual removal of impurities. Due to the high temperature, manual operation is dangerous. Therefore, a de-impurity mechanism for ironmaking process is proposed to solve the above problems. Summary of the invention
