Wholesale u Type Mosi2 Industrial Electric Heating Element With Factory Price
MoSi2 heating elements is a kind of resistance heating element made from Molybdenum Disilicide.
It can be used in air and various gases environments. Working temperature of MoSi2 heating element is 1300C to 1800C. It has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, heating fast, long service life, high temperature low distortion, easy installation and maintenance, excellent chemical stability, which has been widely used as heaters in high temperature furnaces and kilns of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture and chemical industry field.
Types of u type MoSi2 Heating Element

Installation of u type MoSi2 heating element
1) Vertically hanging
Under normal temperature, MoSi2 element is very brittleness, while under high temperature, it is plasticity, so the better way to install U Shape element is to hang it vertically from the furnace top through the support clamping chuck. The aim of such way is to avoid putting the mechanical stress directly to the element heat-generating end; otherwise 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 the element 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.
u type MoSi2 heating element Application:
Item | name | distinction criterion | specification | Using range |
Heating elements | 1700 type | Element operating temperature 1700℃ is acceptable | Le Φ 6-12W type/U type/L type/all kinds of hetero type / stripe shape | high temperature electric resistance furnace |
1800 type | Element operating temperature 1800℃ is acceptable |
1800J type | Element operating temperature≥1800℃ | Le Φ 3-12W type | Special,high temperature and high-power electric resistance furnace |
1800T type | Element operating temperature≤1800℃ | Le Φ 3-12W type U type | Not oxidized special air high temperature electric resistance furnace |
Product use and maintenance
1.MoSi2 heating elements belong to Metal ceramic material. They are hard, crisp and low impact strength at room temperature .Therefore to be careful to avoid damage during transport and installation.
2. When MoSi2 elements continuously operate in an oxidation atmosphere, the surface temperature of 1700 type should not exceed 1700 ° C,1800-type should not over 1800 ℃ and for intermittent use,1700 type-element should not over 1650 ° C,1800type-element cannot exceed 1750 ℃.
Furnace start
If the furnace dry out has been completed or does not need drying, it has to rise its temperature. In order to avoid the oversized electric current impact and cause the electrical equipment overload;
Please go up the furnace temperature according to the following table.
Small furnace (power100KW) | Large furnace(Power 100-500KW) |
Furnace temperature | Voltage | furnace temperature℃ | Voltage |
20-150 | 1/3Operating Voltage | 200-300 | 1/3Operating Voltage |
150-500 | 2/3Operating Voltage | 300-700 | 2/3Operating Voltage |
500-operating temperature | The Whole-Operating Voltage | 700-Operating temperature | The whole-Operating Voltage |
