Description

Heating element molybdenum disilicide mosi2 Straight type U,W,L

1.General description of molybdenum disilicide MoSi2 heating element

1) Definition: MoSi2 heating element is a resistance generate-heating component made from MoSi2 or the basic material.

2) Character: MoSi2 heating element can form SiO2 film which can protect the element not to be oxidized.

3) Usage: MoSi2 heating element can be used for high temperature furnace in ceramics, magnet, glass, metallurgy, refractory etc.

4) Physical property

Volume Density 5.5g/cm3 Porosity 7.40%
Bending Strength 15-25kg/cm3 Water absorption 1.20%
Vickers Hardness (HV)570kg/mm2 Heating Elongation Rate 4%

5) Recommend Surface load

Furnace Temp (C ) 1400 1500 1600 1650 1700
Surface load of hot zone(w/cm2) <18 <15 <12 <10 <8

2. Electric property of MoSi2 heating element

1) Resistance property

The resistivity of element rapidly rises as the temperature rises. Under normal operating conditions, generally the element resistance doesn't change with the service time changing.So the old and new elements can be mixed use.

2) Surface load

According to the structure,the temperature and atmosphere in the correct choice of components surface load is the key element to the hightest life. The picture shows that the relationship among the furnace load under the circumstance that the thermal radiation components is uncrossed.The shaded part is for common surface load---the temperature range.

3.Advices of installation

1) MoSi2 heating element is very brittle under room temperature and plastic under high temperature. So it's the best way for installation of U type element to hang it vertically. Such way is to avoid putting the mechanical stress directly to the hot zone of the element, otherwise, the element will broken easily. If it needs hang horizontally, pls chose a support of high temperature refactory.

2) Pls put the taper part of the element bottom into the furnace chamber to avoid local overheating.

3) The lead wire should be a little longer than the linear distance between the element and the bus to avoid putting the stress to the element.

4) Don't tighten the screw of clamps too much at one time. It can be tightened when the element heats up to high temperature because of the element's plasticity.

5) The temperature of clip should be less than 200°C, the contact voltage between the clip and the element should be less than 0.1V.

6) The distance between the lower end of the clip and the upper surface of the through brick should be more than 50mm, to avoid the radiation heat conduction to the clip.

7) To avoid damage, 170A couldn't be used for long term for the element of φ6/12mm, 300A couldn't be used for long time for the element of φ9/18mm.
