U Type MoSi2 heating elements

The U shaped elements are most frequently used suspended with the bottom of the “U” down. The element consists of two cold ends (Lu) and a U-shaped hot section (Le). The cold ends are twice the diameter of the hot section and are attached by a weld. The extremities of the cold ends are metallized with aluminum to provide a low-resince contact surface to which the electrical connections are made with flat braided aluminum straps.

The two-shank element is available in the following hot zone/cold end diameters: 3/6, 4/9, 6/12, 9/18 and 12/24.

These elements are available in two grades: MS1700 for element temperatures up to 1700 deg C and MS1800 for element temperatures up to 1800 deg C.

From Sep 16, 2011, we have got the MS 1900 MoSi2 heating elements successfully thru the research for 10 years. The max temperature can up to 1850 deg C.

MOSI2 Heating Elements are described by:
Grade: 1700, 1800 or 1900
Diameter: D1/D2, mm/mm
Heated Length: Le*, in. or mm
Terminal length: Lu*, in. or mm
Shank Spacing: A*, in. or mm
Specify Le, Lu and A with the same units (e.g. all 3 as in. or mm).

Examples:
Grade 1800, D1=3mm, D2=6mm, Le=5.5in., Lu=5in., A=.98in.
Specify as: MOSI2, 18-3/6-5.5-5-0.98in.
Grade 1700, D1=6mm, D2=12mm, Le=300mm, Lu=250mm, A=50m
Specify as: MOSI2, 17-6/12-300-250-50mm

Customers of MoSi2 elements enjoy two key added benefits – first, unparalleled price and second, experienced engineering support. Anyone can sell MoSi2, but knowing how to design the system is where excels. MoSi2 systems must be engineered for customer to get the best performance and optimum service life. Duralite engineers can assist in:

analyzing the relationship between the furnace temperature, element temperature and the element surface load selecting the element surface load according to the furnace construction, atmosphere and operating temperature
choosing the most suitable element size and style for your application.
