• Pickling

The process picklling is done with the use of Hydrochloric acid, Lime water, Lubricant oil and soft water. The HR coils is passed into the acid where the carbon on the strips in removed and the same is pass through the lime water and the oil tank so now this material can called as HR Pickled as the carbon is cleaned.

• Rolling

Hr pickled coils is now rolled (reduces the Thickness) to a specific size which is required by our client. As the coil width is 2.00mm it has to be rolled 3 to 4 times for he size of 0.75mm, Rolling some many times make the material Hard and full tempered, which is now called CR full hard.

• Anealing

This process is done with the use of Light Diesel Oil(LDO), Nitrogen and Hidrogen gas and Water. CR full hard material is now put for anealing(making the material soft) on the bell furnace base where in one time it t akes up to 1700mm(i.e 7 to 10 Coils as per thier size) it is covered by a stainless steel pot(so the fire does not rich the material directly) and now it is covered by the bell furnace, the air is socked out and LDO is passed and then it is fired and the temperature is between times on the material so it does not carbon after heating the material is cooled by the help of cooling hood.

• Pinch Pass

Pinch pass is a process of rolling only a single pass as after annealing the material gets very soft and shaky a single pass is given for cleaning, shining and making the material stilled, and lubricant oil is passed on the material as it does not get rusty.

• Slitting

As per the client requirement the material is slit to the size. Packing of the material is done by Plastic and Hessian cloth.
