The grey pig iron (“cast pig iron”) serves as a raw material for foundries to produce various types of cast iron or cast iron materials. Refractory lining of blast furnace A modern blast furnace (BF) is refractory lined to protect the furnace shell from the high temperatures and abrasive materials inside the furnace. With a daily production of 10,000 tons, this results in a coke input of 3,500 tons per day! The Cowper on August 5th has been set and put on heating up. The carbon dioxide gas (\(CO_2\)) reacts with the carbon contained in the coke (\(C\)) due to the very high temperatures and forms the carbon monoxide gas (\(CO\)) as the reducing agent: \begin{align} 4. Fe_3O_4 &~+~ CO  &&\rightarrow~ 3~FeO &&+ ~CO_2 ~~~~~~ \text{(magnetite} \rightarrow \text{wüstite)} \\[5px] Required fields are marked *. The equilibrium then shifts in the direction of the condensation process (this effect can also be seen very clearly on cooled beverage cans, where the water contained in the air condenses and water pearls form). The direct reduction can again be divided into intermediate steps in which the iron content in the ores increases in each case: \begin{align} This leads to a temperature increase of up to 2000 °C. blast furnaces no.1 & 2, thyssenKrupp csa siderúrgica do atlântico, brazil. Published July 11, 2020, It’s hard to find knowledgeable folks on this topic, however you sound like you understand what you’re speaking about! Amongst all the ironmaking processes, the Blast Furnace technology, which has been around the longest, still holds the dominant position. Due to the direct reduction of iron oxides by carbon, one also speaks of a direct reduction. Too low a temperature would again mean the back reaction (indicated by the double arrow in the chemical equation) of the carbon monoxide to carbon dioxide. This combustion is very strongly exothermic, i.e. This is the reason why pig iron has a relatively high carbon content. At low temperatures, carbon monoxide mainly decomposes to carbon dioxide and carbon! However, the BF process relies heavily on metallurgical coke and involves cokemaking and sintering operations, which often attract serious environmental concerns. At high temperatures, carbon reacts predominantly with carbon dioxide to form carbon monoxide (as an important reducing agent). 3. In the blast furnace there are more monolithic refractory products in continuous operation than at any other stage in the steel production process - excluding new linings and interim repairs. Due to the higher density of the pig iron, the pig iron can be cut off at the lowest point of the blast furnace (called tapping). The refractory lining is cooled to further enhance the protection against the dispatch … How important is the “Boudouard reaction” for the blast furnace process? The unmelted iron ores still contain non-reduced iron oxides. This article provides answers to the following questions, among others: The iron in the processed ores must be dissolved out by chemical processes. The iron ore is dressed or crushed into 0.5-1 in. Metallurgy of the Blast Furnace. Blast Furnace Productivity Criteria. Graphite formation is also favoured by a relatively low manganese content and slow cooling. The project realized in August, during capital repair of blast furnace № 5 NLMK, included full service range, from the cleaning of collapsed brick lining until the restoration of protecting layer on the wall and pipe valves by gunning. The corresponding chemical reactions are as follows: \begin{align} Lining thickness be obtained from registration re-sult and is illustrated in Sec. ing points taking from the specific geometry of the blast . The Blast Furnace is a members-only minigame situated in Keldagrim for smelting bars.The furnace here only requires half as much coal when smelting usually, so it can be useful when smelting the ores that require more coal.. This type of solidification is therefore also referred to as stable solidification. The chemical processes are discussed in more detail in the chapter on blast furnace processes. In both cases the iron oxide is reduced to iron. 2018 Blast Furnace Inner Lining Maintenance Use Gunning Material , Find Complete Details about 2018 Blast Furnace Inner Lining Maintenance Use Gunning Material,Blast Furnace Gunning Material from Supplier or Manufacturer-Zhengzhou Sijihuo Refractory Co., Ltd. Blast furnace stack The refractory material is subjected to attack from CO atmosphere, alkalines, and mechanical wear. If the iron ores, which have not yet been reduced, move further down in the blast furnace, then the carbon can also directly reduce the iron oxides contained in the ore due to the high temperatures. Effective Utilization of Energy. Outline of a Blast Furnace Construction. With stable solidification, carbon precipitates in pure form as graphite (grey pig iron)! In this region, the so-called indirect reduction of iron ores to iron by carbon monoxide takes place. At lower temperatures, the reduction takes place indirectly with the help of the carbon monoxide gas formed during combustion (indirect reduction).
