Manufacturing Processes
Hot Rolled Steel Plate Steel Manufacturing Processes
Hot rolled material is annealing in cold rolled annealing furnace and after 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 sheets are dried on brush roll machine before dispatch.
These sheets are again annealing then sent to straighten machine for straightening and pickling in acid and send for packing according to size and quality.
Inspection is done at various stages. By experience staff keeping proper control overall internal process via rolling, annealing, pickling, treatment of waste, etc.
Application
Hot rolled steel has many applications across many industries including
General Steel Fabrication
Manufacturing
Repair
Common applications of hot rolled steel include construction, pipe and tube production, truck frames, industrial doors, roll off containers, oilfield and shale, energy, railroad tracks and more.
