Product Description

Description

MoSi2 heating element is a kind of resistance heating element basically made of high pure Molyndenum Disilicide. In oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of Mosi2 element owing to the high-temperature combustion, which prevent Mosi2 from continuously oxidizing. In oxidizing atmosphere, its max temperature can reach 1800C, and its applicable temperature is 500-1700C. According to shape, it can be divide into "pole" "U" "W". Special shape such as right angle shape and bend angle shape can be produced according to customer's request.


Application

It can be widely used in such applications as sintering and heat treatment of ceramics, magnet, glass, metallurgy, refractory, etc.


Advantage

Mosi2 heating element can quickly form a thin and adhesive anti-oxidizing layer of quartz glass(Sio2), under the high temperature oxidizing condition. If the protective layer was damaged, the element can reform a new one, so Mosi2 heating element has a very good anti-oxidation properties, it also means that the heating element can be used on operation for a much longer time than the traditional one.
The resistivity of the Mosi2 heating element is not changing with the time, so a new one can be installed without effecting the old one, this can result of huge saving in furnace maintenance fee sand time as well, increase the working efficiency, this is the key point of Mosi2 heating element being a better material and being widely used.

Molybdenum disilicide(MoSi2) heating element:
Mosi heating element is a kind of resistance heating element basically made of pure molybdenum Disilicide. In oxidizing
atmosphere, a layer of compact quartz protective film is formed on the surface of Mosi 2 element owing to the high temperature combustion, which prevents Mosi 2 from continuously oxidizing.
In oxidizing atmosphere, its Max temperature can reach 1800 c and its applicable temperature is 500-1700. It can be widely used in such applications as sintering and heat treatment of ceramics, magnet, glass, metallurgy, refractory etc. the commercial name of our Mosi 2 heating element is KERONE Mosi 2 Heating Element.

Installation of mosi2 heating element
1)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.
