3. Production Flow about stainless steel sheet
Raw materials are sending to hot rolling units for rolling into
different sizes
- Hot rolled material is annealing in cold; rolled annealing furnace
and pickling in acid.
- All mill rolls are grinded on precision grinding machine with
proper chamfering after first shiftoperation.
- All sheets are pickled in different tanks and dried on brush roll
machine before dispatched.
- These sheets are again annealing and are sent to straighten machine
for straightening.
- Inspections are done at various stages. Keep proper control overall
internal process via rolling,annealin and pickling by our
experienced staff

6.Manufacturing Process of Stainless Steel Sheet/Plate:
Raw materials are sending to hot rolling units for rolling into
different sizes.
→Hot rolled material is annealing in cold rolled annealing furnace
and pickling in acid.
→All mill rolls are grinded on precision grinding machine with
proper chamfering after first shift operation.
→All sheets are pickled in different tanks and dried on brush roll
machine before dispatched.
→These sheets are again annealing and are sent to straighten
machine for straightening.
→Inspections are done at various stages. Keep proper control
overall internal process via rolling, annealing and pickling by our
experienced staff.

Stainless steel maintenance:
(1) Regular cleaning and maintenance
(2) Pay attention to prevent the occurrence of the phenomenon of
surface scratches
(3) Use soap, weak detergent or warm water to remove surface dust,
dirt
(4) In addition to the surface of the binder with alcohol or an
organic solvent (ether, benzene)
(5) Use neutral detergent or ammonia solution in addition to
surface oil
(6) With 10% nitric acid or abrasive detergent in addition to the
surface of the embroider caused by the dirt.

Application--stainless steel sheet/plate
Stainless steels of various kinds are used in thousands of
applications. The following gives a flavour of the full range:
1.Domestic – cutlery, sinks, saucepans, washing machine drums,
microwave oven liners, razor blades
2.Transport – exhaust systems, car trim/grilles, road tankers, ship
containers, ships chemical tankers, refuse vehicles
3.Oil and Gas – platform accommodation, cable trays, subsea
pipelines.
4.Medical – Surgical instruments, surgical implants, MRI scanners.
5.Food and Drink – Catering equipment, brewing, distilling, food
processing.
6.Water – Water and sewage treatment, water tubing, hot water
tanks.
7.General – springs, fasteners (bolts, nuts and washers), wire.
8.Chemical/Pharmaceutical – pressure vessels, process piping.
9.Architectural/Civil Engineering – cladding, handrails, door and
window fittings, street furniture, structural
sections,reinforcement bar, lighting columns, lintels, masonry
supports
