A large number of steel reheat furnaces are
of the pusher type. These are designed to receive product
from the storage yard or the caster. The furnace must then
heat the product to proper rolling temperature and
uniformity requirements for further processing.
The pusher furnace size is determined by
product dimensions, product grade, required heating time and
production requirements. Modern furnaces are designed to
be fuel efficient and produce low emissions.
The product is moved through the furnace by
pushing one piece against the other with a pusher located at
the charge end. The product can be discharged
mechanically via an extractor, in furnace roller table or
peel bar.
Newer furnaces include computer control with
product tracking, delay management strategies and level 2
thermal modeling. |
