Graphite Heaters & Heating Element

Heating Elements plan and choice is analytic to the appropriate working of any vacuum furnace and is reliant upon various elements: maximum temperature; power load; partial compression and extinguish gases.By far most of vacuum heaters are electrically heated.
Graphite Heaters and heating element are produced from a pure carbon composite giving magnificent temperature consistency, life span, mechanical strength and repeatability. The importance of choosing the right alloy for its construction is very critical because of the heat created and transferred by the heating element.

Heating Element Selection of Material-

The goal in choosing heating elements is to pick a material and cross sectional - area that gives the legitimate electrical resistance in order to generate the desired heat as output. The cross-sectional area of the material determines its resistance. All the other things being equivalent, the larger the cross sectional -area , the lower the resistance.

For higher heat yield applications, the thickness of the element increases, which brings down its resistance and permits more electric flow to stream.
For vacuum furnaces, the heating elements are wide strips to boost both their physical and glowing surface regions.
Stainless steel and nickel-chromium alloys are commonly used for lower temperature applications and at higher partial pressures, while graphite, molybdenum and tungsten are more common for higher temperature processes such as hardening, graphitizing, sintering and nickel or copper brazing.
