• Compact protective layer of quartz glass
• Long life combined with ease of replacing failed elements contributes to a high degree of utilization of the furnace and low maintenance costs.

Installation of MoSi2 Heating Element

 

) Vertically hanging
Under normal temperature, MoSi2 element is very brittleness, while under high temperature, it is plasticity, so the better way to install U Shape element is to hang it vertically from the furnace top through the support clamping chuck. The aim of such way is to avoid putting the mechanical stress directly to the element heat-generating end; otherwise the element will easily be broken.

2) Support clamp
Support clamp are applied to 9/18 and 6/12 two kinds of elements respectively. The support clamp supports the whole weight of the element and the position of the element is also determined by it, therefore, it must be installed carefully to assure the element vertically hung. In order to prevent the element from being over heated locally, the taper part of the element lower end must put into the furnace chamber.

Advantage

• Elements have the capabilities to resistance to oxidation and automatically repair, suitable for continued using in any kinds of oxidizing atmospheres.
• Elements are shaped in hot-working process, which keeps the base material in good tenacity and plasticity at high temperatures. The geometrical figure, standard and dimension is canonical, may produce any special shape and any dimension to meet the customer requirement.
• Because of the special technology, welding spot is fast and shock resistance, which dramatically reduced the damaged probability of welding spot by electric current, as well as transit and installation.

Note: For inquiry, it is better to provide a drawing of the element and specify the element diameters in millimeters. For example, an element with a (d) diameter of 9 mm and a (c) diameter of 18 mm is often referred to as a 9/18 element. Other dimensions may be specified in millimeters or inches.
