The Company has 3 (three) oil-fired, fixed-hearth, reverberatory Melting-cum-Holding Furnaces of bath capacities 3 MT, 6 MT and 8 MT.
The DC Casting unit is flexible to cast 6”, 7” & 9” dia billets in alloys ranging from 1xxx to 7xxx series.
Molten metal treatment is carried out by an Automatic Flux Feeder in conjunction with “eco-friendly” nitrogen degassing. The presence of hydrogen gas in the molten metal is detected using a Gas detector. Further degassing is carried out, if required, prior to casting.
Composition is determined using Direct Reading Vacuum Emission Spectrometer.
‘On-line' modification (wherever required) and grain refining are carried out using Al-Sr and AlTiB / AlTiC respectively. These ensure fine grains and thus, uniform strength along the length of each profile.
The Electrical Homogenizing Furnace is suitable to homogenize billets in various alloys with a temperature control of ± 5°C, a pre-requisite for good homogenizing. Homogenizing of the billets ensures uniform mechanical properties – hardness, UTS, Yield Strength, percentage Elongation etc. besides offering excellent surface for finishing operations such as anodizing, powder coating, electro-colouring, etc
