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

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 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.
