The hot-rolled coil passes through the pickling line, where hydrochloric acidsolution is used to remove surface scale for clean surface finish before further processing and to form a lubrication film on the surface to reduce the coefficient of friction in the drawing and cold working process.
The Gantry Crane moves between the tank during the process. |

This annealing process with the purpose of obtaining spheroidized
carbides facilitatesthe cold works. Once inserted in the
heat treatment furnace, the process takes place in theorder
of controlled heating up to a given time, temperature
and furnace atmosphere, alongwith maintenance at such
temperature during a certain period and cooling controlled
inaccordance with the purpose intended. This process is
controlled by automatic heat cycle. |
