At room temperature, a MoSi2 element is very brittle, while at high temperatures, it is quite plastic. Subsequently, the best way to install the U Shape element is vertically from the furnace crown utilizing the support clamp. This avoids mechanical stress directly on the element hot zone which can cause the element to be broken.
The element holder bears the entire weight of the element and determines the position of the element. Therefore, it must be installed very carefully to ensure the element is plumb. In order to prevent the element from partly overheating, the taper part of the element lower end must be installed in the actual furnace chamber and never in the furnace crown.
The connection strap is made of aluminum braid wire or multi-layer aluminum foil. The outside clamp is not for electrical conduction but only for securing the element. The end of strap should be a little larger than the linear distance between the element and bus.
