Abstract
A heating furnace reheats batches of iron steel products, which differ in their thermal state, introduced in succession into the furnace. The furnace has heating zones followed by at least two equalization zones, the products passing through at least one of these zones, at a speed different from that of the other zones. This speed can be adjusted depending on the thermal objective for the products to be reheated, and at least one of these zones is used as a heating zone.
Claims6
A furnace for reheating batches of steel products having different thermal states and introduced successively into the furnace, the furnace production losses being limited when reheating batches in different thermal states, the furnace comprising:
- an initial heating zone
- a plurality of successively located equalization zone means located downstream of the initial heating zone for equalizing the temperature throughout each product, the equalization zone means being selectively used as an auxiliary heating zone;
- and
- mechanical means for contacting preselected products and passing the preselected products through at least one of the equalization zones at an adjustable speed that is a function of the temperature to which the preselected product is to he heated;
- wherein at least one of the equalization zones is selectively used as a heating zone.
