Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter flux as limestone, dolomite, and sinter and coke for fuel.
There are four general types of cast irons 1. White iron has a characteristics white, crystalline fracture surface. Large amount of Fe 3 C are formed during casting, giving hard brittle material 2. Gray iron has a gray fracture surface with finely faced structure. A large Si content (2-3 wt. %) promotes C flakes precipitation rather than carbide 3.

As the iron travels down the molding line, the temperature gradually decreases from about 1,200 to 900 degrees Fahrenheit. Temperature at this stage varies based on the size of the casting as well as the molding rate. At the end of the mold line, castings enter a shakeout process where the molds are shaken off and the sand is recycled for reuse.
Oct 25, 2019 Lets talk about a few types of furnaces. Blast furnaces These very tall furnaces mostly thought of for metalworking, are injected with pressurized gasses. Theyre generally used for extracting iron and some other metals from their ores. The blast furnace can cast ingots of alloys for use in foundries that manufacture other products.
