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?

Molybdenum and graphite are the most popular choices as hearth materials in vacuum furnaces. Throughout the last 40 years, the heat treating industry has experienced a significant shift in the type of hot zone most commonly used in furnaces. In the 1970s, most of the heat zones installed were all-metal hot zones. Today, however, the vast majority are graphite-based hot zones. But, what is the most efficient design in order to minimize hot zone losses and reduce power consumption?
