Smooth higher temperature Mosi2 ceramic heating rods

 

MoSi2 heating element can usually make use of furnace temp from 1300C to 1800C, it's extensively used in the industries of metrallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture, etc...

 

 MoSi2 is a resistance generate-heating component made from MoSi2 or the basic material. It's used in high temp 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 temp. It's used to the hightest tem up to 1800C during oxidizing atmosphere.

 

Why Molybdenum Disilicide (MOSi2) ?

Reliable Production, Low Maintenance

MOSi2 can withstand oxidation at very high temperature Unmatched durability MOSi2 does not age, thus enable connection between existing and new elements

Flexibility

Wide range of temperature range 500°C to 1800°C. Able to expose in many protective atmosphere used in practice

High Productivity

MOSi2 can be used for high surface loadings Arranged in groups to give wall loadings in excess of 100kW/m²

Energy Saving

MOSi2 enable user to startup only when needed

Installation of elements

1. Vertically Hanging

Under normal temperature,MoSi,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 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.

3.wire clip
The wire connection clamp connecting MoSi2 element is made of aluminum woven wire or multilayer aluninum foil. the steel plate outside it only acts as a clamp and isn't used for electric conduction.For&6/12 element, single rowing wire is used ,and for &9/18element,double-rowing wire is used ,the end of the lead wire should be a little larger than the linear distance between the element and bus.

when the element is installed, the thread fixing the wire clip shouldn't be screwed too much at one time, it can be tightened when the element rises to high temperature, as the element has some plastic and isn't easily broken .the temperature of the wire clip generally shouldn't be higher than 200 C .therefore, the contact voltage between the clip wire and element should be lowered to 0.1V, in order to avoid that the radiation heat is conducted to the clip,the distance should not less then 50mm between the low end of the clip and upper surface of the through brick. Generally, the Dia.6 element can't be used of 170A for a long time. The Dia.9 element can't be used of 300A for a long time
