The difference between steelmaking blast furnace and converter
The blast furnace is an ironmaking shaft furnace with a circular cross section. Steel plate is used as the furnace shell, and the shell is lined with refractory bricks. From top to bottom, the blast furnace body is divided into 5 parts: throat, body, waist, belly and hearth. Blast furnace is the main production equipment for cast iron.
The converter refers to a metallurgical furnace with a rotatable furnace body used for steel blowing or matte blowing. The converter body is made of steel plate and is cylindrical, lined with refractory materials. It is heated by chemical reaction heat during blowing without external heating source. It is the most important steelmaking equipment and can also be used for copper and nickel smelting.
