Cast Iron | Machine Design

Steels and cast irons are both primarily iron with carbon as the main alloying element Steels contain less than 2 and usually less than 1% carbon; all cast irons contain more than 2% carbon

Iron Ore Pelletizing Process: An Overview | IntechOpen

Jul 10, 2017· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking This chapter shows the status of the pelletizing process

Hurstwic: Iron Production in the Viking Age

Regardless, the process was inefficient; a lot of iron was left in the slag Modern practitioners doing bloomery smelts do not think this is a bad thing: low levels of iron in the slag seem to predict poor quality iron in the bloom We have analyzed two different blooms that we created and compared them to a Vikingage iron bloom

Cast Iron | Machine Design

Manufacturing Process of Cast Iron Castings

Cast iron that has not cooled evenly produces a lowquality cast Other problems faced during the cast iron process include contamination of the iron, gas porosity (the forming of bubbles in the iron), and problems with the fluidity of the metal The casting process is an art that must be examined and experienced to be fully understood

Spheroidizing – Metallurgical Processes

Spheroidizing is a form of heat treatment for ironbased alloys, commonly carbon steels, in order to convert them into ductile and machinable alloys It is conducted at temperatures that are slightly below the eutectoid temperature (temperature at which the solution is a solid solution rather than liquid), followed by a slow cooling process

How iron is made material, manufacture, making, history

The melted iron might go to a further alloying process, or might be cast into ingots called pigs The slag is carried away for disposal Treating the gases 3 The hot gases produced in the chemical reactions are drawn off at the top and routed to a gas cleaning plant where they are cleaned, or scrubbed, and sent back into the furnace; the

Ore sorting: Efficiently optimise the treatment of ores in

By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations The entire processing line can be planned in semimobile form and consists only of crushers, screens, belts and sorting machines This allows immense cost savings for transport, since the waste rock is disposed of onsite
