Plant's
Special Features
to Ensure World Class Quality
 

Sidewell type Melting Furnace Ensures better temperature control, composition uniformity, higher melt rate and higher yields when melting light scrap
Tilting type Holding Furnace Excellent level control of metal in the launder which results in better quality
On-line Degassing Facility Removes hydrogen and alkali metal impurities from molten aluminium
Ceramic Foam Filter Eliminates inclusions and suspended impurities
Unique 15° tilt Super Caster Eliminates ripple effect, ensures high quality cast coils with better profile, accurate gauge and metallurgical properties to International Standards
Four separate Casting lines,
individually complete with its own Furnaces,
Casters etc.
To ensure casting of four different grades of aluminium products simultaneously, thus reducing lead time drastically
Cold Rolling Mill with automatic gauge control and automatic flatness control Reduction in thickness upto 0.12 mm with gauge accuracy and flatness to International Standards
Annealing Furnace with Nitrogen Controlled atmosphere Ensures brighter surface with no brown stain
Precision Slitters & Cut-to-Length equipment Ensure close tolerance on width, length and diagonal, straight build-up and smooth, tear-free edge
Special Roll Grinder with Millitron System Computerized numerical control cambering maintains stringent tolerance while recording actual profile of the roll in the form of a chart

 
Along with the above, the plant has facilities for analysis through Optical Emission Spectrometer, fully computerized Tensile Testing Machine, Hydrogen Analyser, combined with an overall close vigil on process and an all-round in-line Quality System Standard from input to finished product conforming to World Class Standards.
