HEAVY FOUNDRY & LADLE BAY ARCHITECTURE

Molten Extreme
Heavy Foundry Coat
3-Layer Thermal Armor (~615 g/m²).

Engineered against intense infrared radiant heat waves at furnace fronts, melting bays, slag skimming stations, and ladle pouring lines. Integrating a 350 g/m² non-stick outer shell with a ~150 g/m² 100% meta-aramid felt thermal barrier and ~115 g/m² woven inner lining, the breathable non-aluminized Molten Extreme Coat elevates radiant heat protection to Class C2 (RHTI24 = 37.4 s).

Quick-Release Emergency Engineering: Equipped with an instant quick-release front storm placket so an operator can shed the coat in a single motion during a severe splash emergency. The collar opening and seams follow downward trap-free geometry under EN ISO 11612 Clause 4.2.

3-LAYER ANATOMY (~615 g/m²)

3-Stage Shield Against Radiant Heat and Molten Splash

Each layer of the breathable non-aluminized composite neutralizes a distinct thermal threat, assembled without lamination to preserve insulating micro-air gaps and vapor permeability.

1. OUTER SHELL (LEIDENFROST NON-STICK SHIELD)

350 g/m² MARLAN PLUS

  • Composition: 60% CV FR, 20% Pure Natural Wool, 10% PA, 10% TENCEL™
  • Leidenfrost Micro-Vapor Cushion: Within MARLAN PLUS, keratin/hydrophobic lipid sheaths and 7–9% cellular moisture in its 20% wool create a microscopic gas film upon 780–1400°C impact, shedding droplets in <1 s with zero wetting.
  • Extreme Pour Proof: Zero aramid on the outer face; zero adhesion verified in the Marina Textil 1,050 g (5.25× D2 / 3× D3) extreme pour test.
2. MIDDLE LAYER (THERMAL BARRIER)

~150 g/m² Meta-Aramid Felt

  • Composition: 100% Meta-Aramid needle-punched non-woven felt
  • Function: Elevates ISO 6942 radiant heat resistance to Class C2 (RHTI24 = 37.4 s).
  • Thermal Attenuation: Absorbs intense infrared waves radiating from open furnace doors and rotary kiln (~1450°C) inspection ports.
3. INNER LAYER (WOVEN LINING)

~115 g/m² Aramid / FR Viscose

  • Composition: 55% Aramid / 45% FR Viscose woven lining
  • Function: Provides low-friction internal glide for rapid donning and instant emergency shedding.
  • Skin Comfort: OEKO-TEX® Standard 100 certified, -32% lighter breathable comfort compared to bulky ~900 g/m² garments.

Liquid Aluminum vs. Liquid Iron: Specific Heat (cp) & Latent Heat of Fusion (ΔHf)

In ladle pouring and slag skimming, molten aluminum (~750°C) carries substantially higher thermal energy per unit mass than molten iron (~1400°C):

  • 🔥 Specific Heat Capacity (cp): Molten Aluminum 1.08 J/g·K vs. Molten Iron 0.82 J/g·K (+32% higher thermal storage capacity).
  • ⚡ Latent Heat of Fusion (ΔHf): Molten Aluminum 397 J/g vs. Molten Iron 247 J/g (+61% higher solidification heat release plus ~94 W/m·K thermal conductivity).
  • 🛡️ 3-Layer (~615 g/m²) Solution: The Leidenfrost micro-vapor cushion sheds 357–360 g aluminum (D3) and 208–212 g iron (E3) without sticking, while the ~150 g/m² Meta-Aramid felt core raises ISO 6942 radiant resistance to Class C2 (RHTI24 = 37.4 s).

HYGROSCOPIC MOISTURE CONTROL & THERMAL PHYSIOLOGY

Furnace-Front Steam Scald Burn Prevention Mechanism

Under intense infrared radiation when furnace doors open, liquid sweat trapped inside impermeable synthetic coats flashes to 100°C (expanding 1,600× in volume), causing severe Steam Scald Burns even without garment ignition.

  • 💧 3-Layer Hygroscopic Vapor Diffusion: The inner lining (45% FR Viscose) and MARLAN PLUS outer shell absorb moisture in the vapor phase before liquid sweat films form behind the felt barrier.
  • 🌬️ Scald Burn Protection: Eliminates internal steam scald hazards across extended furnace-front and ladle shifts.

Engineering Note: Molten Extreme is a breathable textile composite; it is not aluminized, not C3 and not C4. At -32% lighter weight than impermeable ~900 g/m² approaches, it reduces metabolic heat stress while delivering continuous shift-long Class C2 radiant heat and D3/E3 splash safety.

FOUNDRY SAFETY GEOMETRY (EN ISO 11612 CLAUSE 4.2)

Emergency Quick-Release & Trap-Free Cut

During heavy pouring and pyro-processing operations, rapid garment egress in a splash or blowback event is vital. Molten Extreme is engineered strictly under EN ISO 11612 Clause 4.2 design rules:

  • ⚡ Quick-Release System: Front closure opens in a single pull during emergencies so the coat drops free in seconds.
  • 🛡️ Full Double-Layer Storm Placket & Trap-Free Front: Fasteners are completely shielded by an external double FR storm flap with zero external patch pockets or upward folds where slag could lodge.
  • 📐 Downward Waterfall Seams: All exterior seams overlap downward to accelerate molten runoff; strictly no pleats or cuffed/folded hems.
  • 🚨 2.5 cm Sewn FR Tape (EN ISO 20471 / EN 17353:2020 Type B2): Certified 2.5 cm sewn flame-retardant retroreflective strips provide 360° visibility to overhead crane and forklift operators.
  • 🔒 EN 1149-2 Induction Insulation & Isolated Hardware: Outer fabric provides EN 1149-2:1997 (1.78 × 10⁸ Ω vertical resistance) and EN 1149-5 antistatic protection with zero internal thermal bridges.
GROUP B FULL-BODY PPE PAIRING (LADLE POURING & ~1450°C ROTARY KILN LINE)

For full-body integrity at ladle pouring bays, furnace charging/slag skimming, and rotary kiln (~1450°C sintering / burner pipe inspection) stations, pair Molten Extreme Coat (~615 g/m², C2 = 37.4 s) with the collar-interlocking Korgan Detachable FR Hood + Korgan Trousers (350 g/m², D3/E3) and a 95% IR-reflective gold-coated visor.
