| Summary |
FOSCAST steel lances are used for the introduction of
powder reagents or inert gases deep into steel for the
purpose of refining and for temperature and compositional
homogenisation. |
|
| Description |
FOSCAST steel injection and steel stirring lances are
of monolithic construction and produced from high alumina
(85-95% Al2O3), low and ultra low cement castable. Sizes
range from 180mm to 230mm in diameter and each lance
is custom designed, with optional reinforced slag lines
and single or multi port configuration. Lives will vary
depending on factors such as steel temperature, length
of injection and slag viscosity. |
|
| Application |
The injection lance is an integral part of the injection
process. |
|
| Function |
Gas purging/powder injection is a key part of the steel
refining process. The introduction of alloys or treatment
agents by this means ensures faster assimilation and
maximum efficiency of the process. In the case of gas
purging the process is essential for temperature and
compositional homogenisation before casting. FOSCAST
steel lances have a reputation for reliability and consistency. |
|
| Benefits |
 |
Excellent strength and reliability due to the quality
of the refractory. |
|
Consistent performance over an extended life. |
|
Custom design ensures the range of injection and
steelplant conditions can be met.
|
|
Porous plugs are available for gas stirring.
|
|
With single or multiple outlet ports available.
