The General Descrioition Of furnace heating element
1.MoSi2 heating element is a kind of resistance heating element basically made of high pure Molybdenum Disilicide.
2.MoSi2 heating element
1) Main type :U, W ,UL, WL, Rod . Material grade :M1700,M1800,M1900.
2) Standard dimension (mm):3/6,4/9,6/12,7/14,9/18,12/24.
3.It can be widely used in such applications as sintering and heating treating of ceramic ,magnet ,glass,metallurgy ,refractory,ect.
4.physical property

| Hydrogen | 1100~1450°c | 1100~1450°c |
| N2/H2 95/5% | 1250~1600°c | 1250~1600°c |
6.Recommend surface load:
| Furnace Temp(°c) | 1400 | 1500 | 1600 | 1650 | 1700 |
| Surface looad of hot zone(W/cm²) | <18 | <15 | <12 | <10 | <8 |
7. 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 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.
