Aluminium shots and knotch bars are used as deoxidiser in steel plants. The deoxidisers are of two types: (i) Aluminium (ii) Ferrosilicon. Aluminium has certain advantages over the Ferrosilicon, as it is cheaper and can be easily made in the form of shots or ingot. Aluminium shots have the comparative advantage i.e. they offer greater surface area in better contact and mixing.
The demand for product is mainly from steel making plants like Durgapur, Bhilai, Rourkela, Salem and small plants having induction furnaces. The demand per annum as presumed is over 1500 M.T. for Aluminium shots. There are units manufacturing this product in Orissa and West Bengal. In Rajasthan a unit can be set up to cater to the needs of the State and neighboring States for small/mini steel plants.
Aluminum Notch Bars are manufactured using aluminum that is 93% or 97% pure. These Notch Bars are used as de-oxidant agents in steel industries.
