The ladle refractory lining temperature, during the production cycle, especially for basic linings, must be constantly reset and maintained at convenient temperature values higher than 1.000°C-1.200°C. A correct management of ladle heating and temperature keeping, allows to improve the main steel making parameters:
* Low liquid steel temperture changings before and after tapping
* Tapping temperature decrease at E.A.F. (5-10°C)
* Consumption reduction of expensive energy (i.e. reduction electrical energy of the E.A.F.)
* Electrode consumption reduction of the E.A.F.
* Reduction of Tap to Tap time at E.A.F.
* Increase of E.A.F. productivity
* Guarantee of casting start in the C.C.M.
* Low ladle refractory lining consumption
* Increase of safety refractory lining performances
* Elimination of liquid steel infiltrations trough / behind the working lining
Ladle Preheaters Combustion Technology
* High efficiency gas – air burners
* High velocity and long flame burners
* Pulse firing burners or modulating burners
* Low NOx emissions of burners
* Burnes designed and manufactured with special refractory steel parts for long life time of operation
* Micro / PLC Automatic control of burners combustion ratio
* Automatic and efficient control of ladle temperature
* High preheating performances
* Extraordinary uniformity of ladle lining temperature
* Low gas consumption
* Shorter drying – preheating time
* Significant energy saving compared to usual technology
* High efficiency thermal recuperators (additonal energy saving 30%)
* Burners available for natural gas, L.P.G., Diesel oil, Coke oven gas
* Emission rates according to E.C.C. standards
* Exhaust fumes system and post-combustion system for dangerous and smoking emissions
