Pyrotek (Pyrotek Inc.) Foundry & Molten Metal Components

Pyrotek (Pyrotek Inc.) molten metal systems and components: SIVEX® and Pyropore® ceramic foam filters, Rigid Glasweve®, ZX-grade graphite rotors for SNIF™ and STAR degassers, Ceramite® launders, BN coatings, and pumps.

SIVEX® and Pyropore® Ceramic Foam Filters

SIVEX® alumina filters remove oxides and dross in molten aluminium boxes with PLC preheating. Pyropore® uses ZrO2, SiC, Al2O3, or alumina-graphite for aluminium, copper, and ferrous alloys. Cells trap fine inclusions. Spares include filter bowls and seals.

Alloys: Al, Cu, iron, steel
Grades: Al2O3, ZrO2, SiC
Modular box: steel shell + PLC
Spares: filter bowls and seals

Rigid Glasweve® & BPF® Pump Filters

Rigid Glasweve® fibreglass sprue filters replace steel mesh in low-pressure lines without iron contamination. Lighter than molten aluminium, they float for skimming during remelt. Bonded Particle Filter (BPF®) units use 6–12 grit media. Flow ratings reach 320 or 680 kg/min.

Process: LPDC, permanent mould
Remelt: zero iron contamination
BPF® media: 6 to 12 grit
Flow rates: 320 & 680 kg/min

ZX-Grade Graphite Rotors, Shafts & Seals

Pyrotek graphite shafts, Starburst rotors, and stators fit STAR batch and SNIF™ in-line degassers plus OEM units. ZX-grade graphite doubles oxidation life over standard grades. Three graphite grades cover varied melt duties. Ceramic-fiber shaft seals limit creep relaxation.

Fits: STAR, SNIF™ & OEM units
ZX graphite: 2x oxidation life
Design: Starburst rotor, stator
Seals: graphite-coated fiber

SNIF™, STAR Degassers & Flux Injectors

SNIF™ units use 1–4 spinning nozzles (P-30, P-140, TD-1500, HD-2000, PHD-50) to strip hydrogen from aluminium. STAR 3000 and STAR 3500 rotary units offer fixed, mobile, or hoist mounts. FIT and PLC-driven FIM lances inject flux below melt level. Spares cover nozzles and shafts.

SNIF™ line: 1 to 4 nozzles
STAR series: 3000 & 3500 models
Injectors: FIT pneumatic & FIM
Spares: nozzles, shafts, lances

Ceramite® & Pyrocast Refractory Launders

Pyrotek trough systems combine steel shells, insulation, and precast linings in Pyrocast FS73 AL, FS76 AL, XP, SC460, and Ceramite® CSA/CSR/SFW. Heated lids hold melt temperatures within 5 °C. Non-wetting joints simplify cleaning. Replaceable parts include trough sections and dams.

Materials: Pyrocast, Ceramite®
Thermal hold: within 5 °C
Surface: non-wetting hot face
Spares: precast sections & dams

Boron Nitride (BN) Coatings & Salt Fluxes

Pyrotek supplies ZYP Coatings Inc. high-temperature boron nitride (BN) paints and release agents for non-wetting refractory protection. Salt fluxes span seven types: covering, cleaning, drossing, alkali refining (Mg, Ca, Li, Na, K), wall cleaning, grain refining, and eutectic modification.

Coatings: ZYP boron nitride (BN)
Fluxes: 7 metallurgical grades
Refining: Mg, Ca, Li, Na, K
Forms: powder, granular, tablet

Molten Metal Pumps, LOTUSS & MCS Units

Mechanical pumps (J, M, S, D, and Tensor) handle circulation, gas injection, and transfer, while OTS halves dross. Solid-state EMP units and portable RFM® drain-out pumps transfer melt cleanly. LOTUSS melts scrap at up to 10,000 kg/hr in 51 cm+ bath depth. Spares cover impellers and shafts.

Pump lines: J, M, S, D, Tensor, OTS
Portable: RFM® drain-out pump
LOTUSS: up to 10,000 kg/hr
EMP & MCS: precision dosing

RFM® Thermocouples & Steady Eddy Controls

Pyrotek thermocouples use plain or enameled iron, RFM® fibreglass, and ceramic protection tubes in furnaces, crucibles, and troughs. Steady Eddy units regulate headbox metal level for continuous sheet runs. Consumables include ceramic floats and 3.962 × 3.658 cm graphite plugs.

Tubes: iron, RFM®, ceramics
Level unit: Steady Eddy assembly
Plug size: 3.962 × 3.658 cm
Spares: floats, stems, sensors

Pyrotek Molten Metal Filtration & Transfer Architecture

Pyrotek (Pyrotek Inc., Spokane, WA, USA; 40 manufacturing plants across 35+ countries) engineers end-to-end molten metal treatment and transfer equipment for aluminium, copper, and ferrous foundries.

Mechanical pump systems (J, M, S, D, and Tensor series), overflow transfer systems (OTS, cutting dross by half), solid-state EMP units, and portable RFM® drain-out pumps move liquid aluminium safely while BPF® bonded particle filters (6–12 grit, 320 or 680 kg/min) protect pump impellers.

Downstream filtration relies on SIVEX® alumina ceramic foam filters in PLC-preheated filter boxes, Pyropore® foundry filters (ZrO2, SiC, Al2O3, alumina-graphite), and patented Rigid Glasweve® fibreglass sprue filters that float on remelt baths without adding iron contamination.

Degassing Units, Refractory Launders & Protective Consumables

Hydrogen and alkali removal is handled by SNIF™ in-line and furnace spinning-nozzle units (1–4 nozzles: P-30, P-140, TD-1500, HD-2000, PHD-50), STAR 3000 / 3500 batch rotary degassers, and FIT/FIM subsurface flux injectors.

ZX-grade graphite shafts and Starburst rotors double oxidation life over standard graphite and pair with graphite-coated ceramic paper shaft seals.

Precast trough sections in Pyrocast (FS73 AL, FS76 AL, XP, SC460) and Ceramite® wear-resistant linings, backed by heated lids holding temperatures within 5 °C, ZYP boron nitride (BN) coatings, seven classes of treatment fluxes, RFM® thermocouple tubes, and Steady Eddy level controls complete the circuit.
