Keeping furnace downtime to an absolute minimum also means to be able to make the right choice of hot zone. In fact, the hot zone contributes to the performance of the whole system. It has an impact on the process quality, the temperature uniformity, the heating and cooling rates and the furnace's energy consumption. Therefore, which is the hot zone most economical and best performing based on losses and overall power costs? Graphite-based or all-metal design?

As we all know, global events have led to a significant increase in energy cost in the past two years all over the world.

In Europe, current natural gas prices (February 2023) have more than doubled compared to the same period of 2020. In Italy, the cost of one MWh of electrical energy is about 3 times what the cost was just 1 year ago. Moreover, the strong price uncertainty makes difficult for companies to forecast the energy-related costs involved for the next few months.

Energy-intensive industries are largely impacted by price inflation; among them foundries, the metalworking industry and, of course, commercial heat treaters and companies performing in-house heat treatment of any sort.

Heating a load to a determined temperature for some time requires a certain amount of energy; whether that energy is generated from fossil fuel (coal, natural gas, petroleum) or renewable resources (solar power, wind power, hydropower), that is an inescapable reality.
