JJRS Annealing Pickling Line with continuous furnace
The first of the primary cooling sections is the slow cooling chamber, where two variable speed blowers circulate the atmosphere gas through two water-cooled heat exchangers. The second of the primary cooling sections is the fast cooling chamber, where the strip is cooled by a variable speed fan and the cooling length is determined by the positions of three dampers along its vertical length. This chamber is also split vertically for temperature profile control across the width of the strip using a scanning pyrometer.
The overaging chamber provides electrical heating to maintain the strip at an intermediate temperature.
The secondary cooling section cools the strip by variable speed cascaded fans blowing recirculation atmosphere gas cooled by water-cooled heat exchangers.
Final cooling is achieved by spraying and immersion in water.
To prevent oxidation of the strip, the atmosphere around the strip inside the furnaces is a controlled mixture of H2 and N2 (cracked ammonia NH3 providing 5% H2 and 95% N2) although hydrogen only is sometimes used. The furnaces themselves are sealed gas tight and each of them is maintained under slight positive pressure
