The Role Of Metallurgical Equipment Blast Furnace

 Ferro-silicon has a wide range of uses and the market demand is gradually rising. People's understanding of ferrosilicon is also more comprehensive and detailed, but for the majority of users, they only understand the use and function of ferrosilicon but do not understand the smelting equipment for ferrosilicon, the blast furnace. Ironmaking is generally carried out in the blast furnace, metallurgical equipment to blow hot air into the furnace so that the raw materials are heated, so the blast furnace is also called blast furnace, blast furnace raw materials used mainly iron ore (sintered ore, pellet ore), limestone and coke. Because the nature of carbon is more active than iron, so it can take away the oxygen from the iron ore while leaving the metal iron.

    The blast furnace cross-section is a circular iron-making shaft furnace, with steel plates for the shell, shell lined with refractory bricks. The body of the blast furnace from top to bottom is divided into furnace throat, furnace body, furnace waist, furnace belly, furnace cylinder 5 parts. Due to the advantages of good technical and economic indicators, simple process, large production capacity, high labor productivity, low energy consumption, etc., this method of iron production accounts for the majority of the world's total iron production children.

  When the blast furnace production, metallurgical equipment from the top of the furnace loaded with iron ore (sintered ore, pellet ore), coke, slagging with melt (limestone), from the lower part of the furnace located along the perimeter of the wind blowing into the preheated air. The carbon in the coke (some blast furnaces also blow pulverized coal, heavy oil, natural gas, and other auxiliary fuels) is burned with the oxygen in the blast air at high temperature to produce carbon monoxide and hydrogen gas, which is removed from the oxygen in the iron ore during the rise in the furnace, thus reducing the iron. The refined iron is released from the iron mouth. The unreduced impurities in the iron ore and the melt such as limestone combine to produce slag, which is discharged from the slag mouth. The gas produced is discharged from the top of the furnace and, after de-dusting, is used as fuel for hot air furnaces, heating furnaces, coke ovens, boilers, etc. The main product of blast furnace smelting is pig iron, and there are by-products of blast furnace slag and blast furnace gas.
