Stein Reheating PF, pusher furnaces
Stein Reheating Pusher Furnace (PF): high efficiency, low cost heating solution
Stein Reheating PF is a conventional solution for heating products that works by pushing products through the combustion chamber. The simple mechanical system and near-total lack of cooled elements inside the heating chamber ensure the pusher furnace offers high efficiency and very low operating costs.
The heavy-duty Stein Reheating PF is designed to heat products from carbon, alloy, stainless or special steels by offering low fuel consumption and high efficiency:
- Top-fired pusher furnaces for billets 15 - 100 t/h
- Top and bottom-fired pusher furnaces for billets, slabs, blooms and beam blanks 60 - 300 t/h
Fuels including natural gas, fuel oil, COG, BFG, mixed gas, etc. can all be utilized thanks to the state-of-the-art AdvanTek® burners. The charging and discharging machines can be customized according to the application and layout. All installations can be prefabricated if desired.
Stein Reheating PF advanced design
Fives has improved on the basic design to develop a new concept of pusher furnace called the LC2® (Low Cost/Low Consumption), which gives customers a high return on investment in these types of installations and a significant reduction in overall maintenance costs. The main features of the LC2® pusher furnace include:
- New lining patterns to reduce heat losses
- Top firing for solid hearth design
- Pusher machines, extractors and roller tables
- Megasider Zaragoza, Spain
Megasider Zaragoza Rico & Echeverria (now ArcelorMittal Zaragoza) entrusted Fives with the construction of a top-fired pusher furnace of 70 t/h capacity, equipped with lateral discharging by means of kick-off machine and rollers. Much of the technology was pre-assembled in Fives’ workshop, reducing construction time and resulting in an improvement in quality. It also features the Virtuo® Level 2 thermal solution.
- SteelAsia, Philippines
SteelAsia Manufacturing Corp. (SteelAsia), one the world’s largest rebar manufacturing companies, entrusted Fives with a contract for a new pusher furnace at its Meycauayan Works in the Philippines. The new pusher furnace replaced an old furnace at Meycauayan Works.
Fives was entrusted with the contract to convert the existing pusher furnace from front discharging by ramp to side discharging by peel bar, enabling an increase in capacity from 60 t/h to 80 t/h thanks to the extended furnace length and the addition of one new control zone with flat flame roof burners. In addition to the capacity increase, the modifications also enabled energy savings by reducing the furnace’s openings and limiting air inlets.
