In-line quenching and self-tempering of deformed bars.

A- Water quenching line

The water quenching line includes:

- Two (2) water boxes (waterbox A and B) each one consisting of:

•  a fabricated steel structure where the cooling elements (coolers, water strippers, air dryer, by-pass pipes) are

          fixed to the frame on machined support/delivery pipe arrangements for a perfect alignment. Quick

          locking/unlocking by hand wheel;

• water system with external main pipe and delivery pipes to each cooling element;
• ON-OFF valve for each cooling element;
• water sprayers inside the box to externally cool the by-pass pipes;
• protection cover.

- A roller table to convey the bar to the downstream services when the in-line treatment is not required. Included in

   a separate item.

- A shifting car designed to support and shift the waterboxes and the roller table into working position in accordance

  with the product being rolled. It consists of a welded steel frame mounted on idle wheels running on foundation

  rails; shifting movement by hydraulic cylinders. Maintenance platforms along the waterboxes.

B- Waterbox

Each water box of the water cooling line includes:

A water box consisting of:

•  a fabricated steel structure where the cooling elements (coolers, water strippers, air dryer, by-pass pipes) arefixed to the frame on machined support/delivery pipe arrangements for perfect alignment.
• Quick locking/unlocking by hand wheel.
• water system with external main pipe and delivery pipes to each cooling element.
• ON-OFF valve for each cooling element.
• water sprayers inside the box to externally cool the by-pass pipes.
• protection cover with opening/closing by hydraulic element.

C- Waterbox by-pass roller table

Installed on waterbox side, on the shifting car.

Consisting of:

• Fabricated steel frame with covers between rollers.
• Independently driven rollers mounted on double supports with roller bearings..

D- Valve bench

The valve bench is a welded steel structure housing all the components necessary to control water flowrate, such as:

• flow control valve(s)
• electropneumatic converter(s)
• magnetic flow meter(s)
• pressure regulator(s)
• pressure gauge(s)
• pressure transmitter(s)
• miscellaneous valves (ball valve, butterfly valve, etc).

The valves are controlled by a PLC to obtain a given flowrate according to the temperature set for the cooling process.
