Finishing
Mill:
The finishing stand is 4-High Steckel mill supplied by United
Engineering Corporation. The mill is equipped with Hydraulic
Automatic gauge control. The thickness and profile of the strip
is measured during rolling with the help of X-Rays and Automatic
gauge control facilities, supplied by M/s DAVY-LOEWY ENGLAND
the world leaders in AGC equipments.
The available on line datas are continuously monitored by computer
which helps in producing HR Coils with best tolerances and surface
finish. While producing the coils, the strip is coiled in the
Steckel mill coilers housed in the furnaces above the roller
tables provided on either sides of the finishing mill. This
helps in maintaining sufficient temperature of the strip to
facilitate rolling. To and fro rolling is done with the strip
on either side of steckle mill.
Laminar Strip Cooling:
The strip cooling system is equipped with laminar cooling
with precise control over rte of flow of water for cooling hot
strip. This enables to achieve desired cooling temperature and
metallurgical properties for the entire product.
Down Coiler:
The hot strip mill has a Hydraulic / Pneumatically operated
Down Coiler with retreat to wrapper rolls during cooling with
reference to head and movement i.e. jump control. This facilitates
compact coiling without damaging the surface of strip by wrapper
rolls even all high coiling speeds.
Plates are ultrasonically tested and Mill Test Certificate provided
along with the supplies. |
