1.molybdenum disilicide heater /MoSi2 heating element 2.typeU,W,UL,WL,Rod ., 3.Dia(mm):3/6,4/9,6/12,9/18,12/24, 4.CE proved - details see: https://www.machineto.com/factory-price-molybdenum-disilicide-mosi2-heating-element-10247394

STA MoSi2 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 1850C during oxidizing atmosphere. According to your request, our company can produce the products of Rod , "U", "W" and "U"-right angle ,"W" --right shapes, etc.

MoSi2 heating element can usually make use of furnace temperature from 1300C to 1850C. It is extensively used in the industries of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture, etc.. It is an essential ideal element when the products are sintering in the high temperature

Installation of elements:

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 UShape 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 veryically hungin order to prevent the element from being over heated locally,the taper part of the element lower end must put into the furnace chamber.

Notice to Furnace Operation:

To avoid high current surges which may cause damage to MoSi2 Heater Molybdenum Disilicide Heating Elements , the recommend starting procedure as following:

Small Furnace (Power 100KW)		Big Furnace (Power 100KW-500KW)
Furnace Temperature .C	Voltage	Furnace Temperature .C	Voltage
20-150	1/3	20-300	1/3
150-500	2/3	300-700	2/3
500-Working Temperature	Full	700-working Temperature	Full
Note: Shifting gear must be done quickly, otherwise high current surges may cause damage
