Más detallesHow does the blast furnace work? The Blast Furnace is a large steel structure about 30 metres high. It is lined with refractory firebricks that can withstand temperatures approaching 2000 o C. The furnace gets its name from the method that is used to heat it. Preheated air at about 1000 o C is blasted into the furnace through nozzles near its base.. The largest Blast Furnaces in the UK
Más detallesprocess which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent. The metallic iron produced by such a furnace contains a relatively high proportion of carbon (4%) and is passed to the steelmaking process as a liquid at approximately 1450C, called "hot
Más detallesPrimary steelmaking uses mostly new iron as the feedstock, usually from a blast furnace. Secondary steelmaking is performed in an electric arc furnace and uses scrap steel as the primary raw material. Refining consists of purifying an impure metal. Wrought iron
