SCRAP & ITS CATEGORIES
Ferrous scrap recovery is a process that reclaims ferrous metallics from slag muck and debris arising out of iron & steel making which was hitherto considered as a waste, was started in an effort to gain for the country crores worth of metallics recycled annually thereby saving precious raw - materials.
 
Over a period of time, it has been established that usage of ferrous scrap to produce steel leads to considerable savings in energy and natural resources.
 
Production of one tonne of raw steel from steel scrap when compared to BF / BOF route results in.
 
  • 74% savings in energy;
  • 90% saving in virgin materails - one tonne of scrap would lead to savings of 1.5 mt. iron ore, 0.9 mt. of coking coal and 0.5 mt. of lime stone.
  • 40% saving in water requirements and 76% reduction in water pollution.
  • 85% reduction in air pollution, and
  • 97% reduction in mining wastes.
  • In iron and steel making an estimated metal loss ranging between 4 to 7% of metal produced occurs in each   process which is termed as "scrap".
 
There are mainly two categories of scrap:
 
Primary scrap : Primary scrap is relatively clean and almost free from slag & its recovery does not require separation from slag. Its processing involves downsizing for remelting in steel making.
 
Secondary scrap : Secondary scrap is found mixed with impurities like slag, debris, muck, refractories etc. and requires a special and capital intensive mechanised process for recovery.
 
SCRAP RECOVERY PROCESS.
 
Manual process :
 
Hand - picking of scrap.
Chiselling and hammering of large pieces manually.
Hand loading.
Semi - mechanised process :
 
Combination of manual operations picking and breaking to size.
Usage of small capacity handling equipments for loading
Mechanised process (mobile) : Heavy duty capital intensive processing and handling equipments like.
 
Crawler electric / diesel crane with magnet.
Hydraulic Excavator
Magnetic separator (mobile)
Mechanised process (stationary) : Fixed plant with facilities of
 
Conveyors.
Hoppers
Feeders
Magnet drums
Screens
Crawler electric / diesel crane with magnet
Hydraulic excavator
