1.Molybdenum Disilicide Heater MoSi2 heating element, 2.type:U,W,UL,WL,Rod, 3 Dia(mm):3/6,4/9,6/12,9/18,12/24, 4.1700,1800,1900 - details see: https://www.machineto.com/1700c-1800c-1900c-heater-molybdenum-disilicide-mosi2-heating-elements-10245034

STA MoSi2 Heater Molybdenum Disilicide Heating Elements can quickly form a thin and adhesive anti-oxidizing layer of quartz glass (SiO2), under the high temperature oxidizing condition. If the protective layer was damaged, the element can reform a new one, so MoSi2 Heater Molybdenum Disilicide Heating Elements have a very good anti-oxidation properties, it also means that the heating element can be used on operation for a much longer time than the traditional one.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 Heater Molybdenum Disilicide Heating Elements is used in the high temperature under oxidizing atmosphere. It will form the SiO2 film which can keep the element from being melted. When the temperature of element is more than 1700°C,the MoSi2 Heater Molybdenum Disilicide Heating Elements must not be used in the temperature between 400°C and 700°C for a long time; otherwise the element will be cremated under the strong oxidizing function in the low temperature.

Main application :

MoSi2 heating element can usually make use of furnace temperature from 1300C to 1800C. 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.
