GF-ELTI Pusher Furnaces with Unilateral Reheating are plants added to rolling lines.
They are continuous conveyor furnaces characterised by full hearth, with GF-ELTI Regenerative Burners placed on top of the charge.
These furnaces are intended to reheat the iron and steel semi-finished products at the correct process temperature (1,100 ÷ 1,250 °C), for the next rolling operation.
The plant is built according to the logic of modular prefabrication, which enables to quicken the on-site assembly stages of the plant.
The furnace consists of walls, vault and hearth and no significant foundation works are required.
According to the layout of the works, the furnace can be equipped with a front or side load and unload system whereas the charge in the furnace is fed through a service machine, named pusher machine.
Due to unilateral reheating, this type of plant involves a furnace of longer lengths, if compared to other plant-engineering solutions.
During maintenance operations, the chamber must be emptied manually and when the furnace is cold.
The types of treated products are typically: billets, blooms, slabs.
