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?

Advanced engineering components require not only better materials but also new joining or welding processes. Recently, diffusion bonding has become a viable process in the fabrication of structural hardware or fluid and gas flow devices for aerospace and electronic industries. This technology heats and applies pressure on joint materials and uses molecular diffusion to bond them. This means that the resulting joint has properties similar or equal to the parent materials. The process has the ability to produce high quality titanium joints so that neither metallurgical discontinuities nor porosity exist across the interface.

As you know, heat dissipation is critical in the thermal process. For that reason, in this video, I'm going to show you how to calibrate the cooling system for an optimal management of your vacuum furnace. A correct calibration ensures greater efficiency of the cooling system and a significant savings in terms of energy consumption of pumps and the water used.
