ZHENG ZHOU STA Laboratory Furnace Molybdenum Disilicide MoSi2 Heating Element

STA MoSi2 heating element is a resistance generate-heating component made from MoSi2 or the basic material. It is used in high temperature under the oxidizing atmosphere, it looks like glass in its surface and form a light SiO2 glass film which can protect the element not to be oxidized. So this kind of element has unique effect for resisting oxidization in the high temperature. It is used to the highest temperature up to 1850C during oxidizing  atmosphere. According to your request, our company can produce the products of Rod or straight , "U", "W" and "U"-right angle ,"W"--right ,Abnormal shapes, etc.

MoSi2 heating element  is used in the high temperature under oxidizing atmosphere. It will form the SiO2 film which can keep the element from being melted. During the oxidizing process, the SiO2 protecting film is formed again when the element continues to be used. The MoSi2 heating element must not be used in the temperature between 400C and 700C for a long time, otherwise the element will be cremated under the strong oxidizing function in the low temperature.

1) Main type :U, W ,UL, WL, Rod . Material grade :M1700,M1800,M1900.

The influence of operation temperature on the heater surface in a different atmosphere

Main application :

They can be widely used in such applications as sintering and heating treating of ceramic ,magnet ,glass,metallurgy ,refractory,ect.

Installation of elements:

1)vertically hanging

 Under normal temperature,MoSi2 ,element is very brittleness,while under high temperature it is plasticity.So,the better way for installation if the UShape element is to hang it vertically,to the furnace top through the support clamping chuck H.The aim of such way is to avoid putting the mechanical stress directly to the element heat-generating end ,or 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 that the element it veryically  hungin order to prevent the element from being over heated locally,the taper part of the element lower end must put into the furnace chamber.
