Sifca^®

General features

SIFCA^® is an acronym that stands for Slurry Infiltrated Fiber CAstable.

SIFCA^® is a precast refractory composite composed of low cement refractory slurry and stainless steel fiber. It is a combination of up to 16 volume percent stainless steel fibers and any one of six (6) slurry types. Under appropriate conditions, SIFCA^® shapes can have a service temperature range up to 1650°C.

General features

The unique characteristics of this product are; thermal shock resistance, impact resistance, compressive strength and refractoriness when compared to steel or cast iron shapes. At elevated operating temperatures, SIFCA^® replaces cast iron and steel parts that are oxidizing. SIFCA^® is also a direct replacement for conventional precast refractory shapes in structural or support applications. SIFCA^® shapes, unlike standard precast shapes, can be bolted to the same structure as the steel or cast iron it is replacing.

Recommended applications

Typical iron and steel applications:

• Steel ladle retainer rings
• Reheat furnace door jambs
• Reheat furnace door perimeters
• Iron ladle pour spouts
• Slag out sections
• Torpedo ladle throats
• Composite tundish covers
• Blast furnace trough and runner covers
• Replace water cooled metal sections

Typical non ferrous applications:

• Furnace door jambs, sills and lintels
• Rotary kiln nose rings
• Cruse bottoms
• Trough and launder sections
• Metal stirring tools
• Siphon tips
• Furnace door perimeters
• Thermocouple protection tubes
• Skim blades

SIFCA^® is a unique refractory composite and is supplied by Thermoheat B.V. as a precast shape only. SIFCA^® can be applicated in the following industries: aluminium, copper, ferrous and non ferrous, hydrocarbon processing, incineration, iron and steel, mineral processing. New applications are continuing to be developed. Thermoheat can furnish additional application information and suggestions.

The application of this product requires close cooperation with the end user. That’s why Thermoheat continually developes new applications.
