BILLET MILL

The Billet Mill has been designed to roll billets from blooms of cross section 325x325 sq.mm in 6 to 12 passes depending on cross section of billets to be produced in the Mill. The capacity of the Mill was designed to roll 15,01,000 Tonns/Year. But with modified output size of billets the mill is now capable of rolling to million tonnes per year

The Mill consists of 12 working stands arranged in three groups.

a. The First group contains Two 2-High Horizontal stands with a 90 deg. tilter in between. These stands are equipped with rolls of diameter 1000mm and length 1200mm.

b. The Second group called the roughing group contains 4 stand - 2 each of Horizontal and Vertical stands arranged alternately. These stands are equipped with rolls of diameter 700mm.

c. The Third group called the finishing group located after the transfer table contains 6 stands - 3 horizontal and 3 vertical stands arranged alternately. These stands are equipped with rolls of diameter 500mm.

Rolled billets after the roughing group of stands which are not to be rolled further are transported by transfer table and by pass roll table to the stationary 800T shear where they are cut into required length. The billets are gathered and transported to cooling bed by roll tables.
Billets from roughing group intended for further rolling in finishing group are transfered to the last group of stands. If necessary, the front end of billet can be cropped off by 250 T shears installed in front of the group.

After rolling in the finishing group, the billets are cut by flying shears into billets of length 5 to 12m. End arisings are controlled by a computer installed in the Mill.
After cutting, the billets are transported to cooling beds by roll tables and transfer skids.
