Preheaters are used to increase the temperature of the container to be comparable to that of the molten metal. The energy efficiency of the melting process is calculate by dividing the amount of theoretical energy needed to melt a metal and raise it to is pouring temperature by the actual amount of energy consumed in melting, treating, holding and handling the material
Ladle are also used to transfer molten metal from holding furnace to the pouring station or shot sleeve of a die cast machine. The automation of the ladle system allows the delivery of molten metal in consistent period for every cycle with accurate quantity of molten metal. The use of auto ladling equipment has become commonplace in aluminum die casting, resulting in less pouring-related casting defects and low burden on the manpower used in hand pouring. Effective insulation of the ladle allows more efficient transfer of the molten metal. This increases ladle capacity and reduces largely operating costs. Other benefits include the ability to maintain the current lining profile, minimize heat loss, and reduce energy consumption
Preheated ladles can also reduce the melting energy required in the furnace. Plants driven by productivity typically tap into ladles that are fully soaked and preheated. On the other hand, plants that are limited in productivity by schedule typically have ladles that are not completely soaked. At this time, most ladle metallurgy consists of wire feeding with limited use of stirring or metal heating.

Benefits of Ladle Preheater
1) Reduced preheating time
Distributed heat input at a high energy density allows quick heating of the ladle. Generally the heating-up times are cut down 50 % and more.
2) Increased durability
A minimal loss of material and an increased durability of the ladle lining are the positive consequences. The temperature control device allows continuously variable temperature regulation and even a precise realization of given temperature curves.
3) 70 % Reduction of operating costs
Energy savings of 70 % are not unusual. This is due to the extremely improved heat transfer and the continuously variable power control, which is the reason for the function for temperature holding at stand-by time.
4) CO2 emission savings
70% less co2 emissions and significantly lower levels of pollutants (CxHy and NOx) mean > 80% reduction of CO2equivalents.
