Heating Element - SiC＆MoSi2

As we have referred in the last Bolger, the SiC and MoSi2 heating element has many types which are according to its shape and application. Now, we continue to introduce the other four types in the following: 

Type HY-G

This type of element is manufactured with a spiral-grooved heating section which is made of homogeneous, high-density silicon carbide crystals. It is more resistant to heat and corrosion than conventional products. It is also able to withstand operations in rigorous conditions.


HY-G elements can operate with a surface temperature of 1700°C in air atmosphere, and up to 1800°C if in inert gas atmosphere (Ar, Ar + Co). Therefore, they are widely used in high temperature furnaces.

The interior of elements with large diameters can be used as a tube furnace. Just as in HY-H elements, HY-G elements are provided with an energy-saving, low-resistance, cold-end terminal.

Type HY-GR

Similarly to type HY-G, HY-GR element is a tubular element with a spiral-grooved heating section, and as a major characteristic, both electrical connections are found at one end only. This type of element is energy-conserving, convenient and easy to install due to the same-end terminal structure.

A special version of this model incorporates a low-resistance cold zone to promote further reduction of expenses.

HY-G and HY-GR elements are recommended for use in rigorous operating conditions or in hot environments where in-furnace temperatures exceed 1400°C.

Type HY-W

The 3 phrase elements are self-bonded silicon carbide formed by re-crystallization of silicon carbide at high temperatures. It consists of three high-purity silicon carbide elements connected at one end by a silicon carbide crossbar. The joints are formed from silicon carbide fully bond the components into a structurally homogeneous body. The elements can be connected directly on three-phase power supply and is a one-side terminal type which permits drawing out the terminals from the roof of the furnace. All elements can be delivered with a wide range of accessories for a trouble-free and energy-saving operation.

Type HY-U
       
This consists of two Silicon Carbide legs with equal diameter. Each leg is divided into two parts, hot zone and cold zone with a joint. Resistance of both legs are equal to ensure a uniform performance. Both shanks are joined with a crossbar made of low resistance.
