Before you begin construction of a blast furnace by yourself, you will be examined in its structure and principles of its action.
Classical blast furnace sectional detailed representation of the image is intended for production of pig iron and ferro-alloys from iron ore.
Note the furnace and its operatingarea specified in figures in drawing. Numeral 6 is a raw material feed zone, and gas locking device located here. Figure 5 - throat furnace serving for the distribution of iron ore in the shaft furnace shown figure 4. The raw ore is heated in a mine, iron is reduced from its oxides. №3 bosh zone serves to soften and melt the iron.
Further, the molten iron passes throughtapered shoulders №2 in the horn that serves to store iron and slag. At the top of the hearth, place pipe №1 compressed air heat, oxygen-rich and fuel. Fuel mixture should heat up to 2000 degrees horn.
Horn follow so that he was a cylindricalinside and outside the cone. Equipping it with devices for blowing hot air for production of pig iron and slag. Gorn- is the main part of the furnace, so its manufacture to Treat very seriously. It should have high levels of strength, fire resistance and tightness.
Build out is also a forge for iron notchrelease of his accumulated slag and pig iron. Lethke equip the dividing bars. Either directly inside the hearth slag lattice arrange for the separation of slag and pig iron in a blast furnace. Iron notch - a rectangular channel with high fire-resistant properties and device closing / opening of the hearth. closing and opening the device must be cooled.
As a foundation, use a massive slab. Concrete desirable. The total mass of the furnace is quite high, so the foundation is to evenly distribute the load on the ground. The plate embed columns that will support the cover of your oven. In the center-slab foundation make monolithic cylinder of refractory concrete, which will draw furnace hearth.
