MoSi2 Heating Element Introduction:
High purity Mosi2 Rod heating element is a resistance generate-heating component made from MoSi2 or the basic material. It is used in high temperature under the oxidizing atmosphere, it looks like glass in its surface and form a light SiO2 glass film which can protect the element not to be oxidized. So this kind of element has unique effect for resisting oxidization in the high temperature. It is used to the highest temperature up to 1800C during oxidizing atmosphere.

MoSi2 Heating element use and maintenance
1. MoSi2 heater 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 heater 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 dryness
New or old furnace not used for a long time needs to be dried before using. Generally, the drying temperature is 100-200℃.
However, if the element is used for a long time under the low temperature, it will cause the low-temperature oxidation.
For little furnace, the drying time is short, the influence of several drying hours is little, but for large furnace, which need to be dried for a long time, you had better open the furnace door to ventilate well. you can open the furnace door ajar with the temperature increment and completely close until the temperature reach 1000℃ above.
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.
