EFFICIENT IRON SINTERING PROCESS CONTROL
· Sintering is one of the iron ore post-processing steps to prepare iron ore fines for a blast furnace. Feed for a sinter plant consists of iron fines, coke, and flux (eg limestone). The feed is placed on a sintering bed, where thermal agglomeration (1300-1480 °C) takes place to produce clustered lumps, aka iron sinter (5-20 mm in size).
Pressing And Sintering Of Powder Parts
Powder Sintering . Powder sintering involves raising the temperature of the green compact, (pressed powder part), to a certain level and keeping it at that temperature for a certain amount of time. The sintering temperature is usually between 70% and 90% of the melting point of the powder metal. This will cause bonding mechanisms to occur between powder particles pressed together in the compact.
