World famous U shape MoSi2 heat element with super quality for industrial furnaces - Yuhao U/W/X/L

1.The General Description

MoSi2 heating elements are resistive heating elements based on molybdenum disilicide. The molybdenum disilicide heating elements prevents the inner core from oxidation by forming a compact quartz glass coating at the surface under high temperature. The temperature generated by MoSi2 goes as high as 1700~1800°C in oxidation atmosphere. They can be widely used in such applications as sintering and heat treatment on electronic ceramics, structural ceramics, magnetic materials, flameproof materials, glass, metallurgy, etc. The resistance of the heating elements is independent on their mission time. The MoSi2 heating elements hardly age, which allows the mixed use of new and old packages.

2. The Species of Yuhao MoSi2 heating elements

Dimension marks of elements:

diameter:D1/D2,mm/mm Hot zone length: Le, mm

Cold end length: Lu, mm Shank spacing: A, mm

Examples:

1) U shape,

D1=3mm,D2=6mm,Le=140mm,LU=125mm,A=25mm

specify as : YuhaoU Shape,3/6×140×125×25

2) W Shape

D1=6mm,D2=12mm,Le=300mm,Lu=250mm,A=50m

specify as : Yuhao W Shape 6/12×300×250×50

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 U Shape 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 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.

3)Wire clip

The wire connection clamp connecting MoSi2 element is made of aluminum woven wire or multilayer aluminum 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.

Look forward to your enqury!
