VERTICAL CHANNEL INDUCTION FURNACE
Slag formation in often inevitable and channel induction holding furnaces require refractories built to withstand slag buildup and
corrosive mechanisms that could potentially lead to unexpected outages. HWI not only offers high performance refractory solutions
to resist the various destructive mechanisms in these vessels, but can assist in engineering a total refractory package to increase
efficiency and extend furnace lifetimes.

Channel induction furnaces are used as holding vessels in iron foundries
to keep iron homogenized and at temperature until it is ready for casting.
Channel induction furnaces are designed as vertical units or horizontal units,
both of which require high performance and tightly installed refractories
to withstand the corrosive slag as well as the mechanical stress from the

Ladle linings can be zoned with different refractory qualities to match wear.
High wear areas can be zoned with high purity materials for superior wear
resistance. Impact pads may consist of a precast shape, a brick assembly,
or a brick and castable assembly. In some cases, the refractory components
are incorporated into a fully assembled bottom or cast shapes that are PRE-CAST LADLE BOTTOM ZONED
