1.Professional manufacturer of the mosi2 furnace heating elements, 2.Any sized elements can be made according to your requiremen - details see: https://www.machineto.com/molybdenum-disilicide-heating-element-as-industrial-heaters-for-furnace-factory-direct-sale-10245543

1)Description

1. General Description:MoSi2 heating elementis 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.

2. Specific Properties: low expansion coefficient, little deformation, stable chemical property, long service life, easy installation and maintenance, etc.

2)Features:

1. used in the high temperature under oxidizing atmosphere,

2. It will form the SiO2 film which can keep the element from being melted.

3. It has unique effect for resisting oxidization in the high temperature.

4. "U", "W" and "U-right angle” shapes heating elements are available.

3)Products specification:

In addition to MoSi2 elements in standard shapes and sizeswe provide customed MoSi2 elements according to customer needs,enabling an optimized element design for each particular application.

5)Installation and Advice

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 aluninum 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.

The brittleness of MoSi2 heating element is relative more under the usual temperature; it also has plasticity under the high temperature. So you had better hang and erect vertically the "U"-shape element. If you need to erect it horizontally, please choose a support of high-temperature insulating materials. The cone-part of the element must extend inside the furnace. At first the fixture of MoSi2 power connector can’t be screwed too tightly. When temperature of the element is going up, please twist it tightly again, so the element is not easily broken.

6)Our suggestion

please choose the specialize power connector provided by our company.The furnace top must be a good function of heat-preservation. In general, the temperature of furnace top can’t be over 300C. The voltage should be low 0.1 between the power connector and the element. In order to avoid radiating heat to pass the connector, the distance is not less than 50mm between the low end of connector and the upside of the ceramic brick. The Dia.6 element can't be used of 170A for a long time. The Dia.9 element can't be used of 300A for a long time.

7) Quality Control

stringent quality control system that meets the standards of ISO 9001.The quality assurance scheme covers all aspects of product quality, including quotations, order handling and shipping, initial design of new element types, inspection of raw materials, in-process inspection and final inspection of the end products.All hot zones are tested during production and this test is repeated on all finished elements.
