SG type SiC Silicon Carbide heating elements(single spiral)

What is sg type sic heating elements?

The spiral sg type sic heating elements are made of special high-density reaction-bonded silicon carbide.

Sg Type Sic Heating Element

Advantage

A spiral slot in the hot zone reduces the cross sectional area. This provides the electrical resistance ratio to make the ends cool and the hot zone hot.

Sg Type Sic Heating Elements In Power Up

Special cold ends may be welded to further enhance the resistance ratio.

Connection method of sg type sic heating elements

To provide a low resistance contact surface the extremities are metallized with aluminum.

Sg Type Sic Heating Elements

The electrical connections are made with flat aluminum braids and spring clamps.

Design Suggestion Of Sg Type Sic Heating Element

X-Distance from the centerline of element to any reflecting surface, such as a refractory wall or product.

Z-Distance from the centerline of the element to a moving or stationary load.

S-Distance from centerline of the elament to the centerline of an adjacent

X=2×Starbar diameter is the minimum,

1.5×Starbar diameter is the absolute minimum and requires a reduced elament surface watt loading.

Z=S÷1.41 minimum for stationary loads

Z=S÷1.73minimum for moving loads.

S=2×Starbar diameters minimum.

The advantages of SG type type SiC heating elements

SG type type SiC heating elements have high-density low-porosity element. They are able to survive severe environments.

The high density prevents the internal lattice structure from being oxidized.

This type element has an extremely slow aging characteristic.
