MODULE 02 // FIRST-PRINCIPLES PHYSICS

First-Principles Physics & NIST High-Temperature Polynomials

Differential energy balance dissecting sensible absorption, austenitic phase transformation enthalpy, and baseline thermal dissipation.

2.1 Four-Zone Piecewise Enthalpy Integration Equations

Global Energy Conservation Governing EquationCBAM ANNEX IV

Q_net = m_steel × [∫(Cp_α dT) + ΔH_phase + ∫(Cp_γ dT)] - Q_recup

Strictly isolates sensible heat and latent phase transformation enthalpy absorbed by moving steel stock, deducting recuperator waste-heat recovery credits (Q_recup) to eliminate overstated factory overhead loading.

Four Thermal Zone Boundary EquationsNIST SRD 69

Z1 Preheat (25°C → 650°C):Q_Z1 = m × ∫(Cp_α dT)

Z2 Heating Phase Change (650°C → 850°C):Q_Z2 = m × [∫Cp dT + ΔH_γ]

Z3 Carburizing / Solution (850°C → 880°C):Q_Z3 = m × ∫(Cp_γ dT) + Q_diff

Z4 Soaking & Diffusion (880°C Equilibrium):E_loss_isolated (Decoupled)

MODULE 03 // ENGINEERING METHODOLOGY & DEFENSE

Physics Assumptions & Model Boundary Conditions

Engineered strictly under NIST thermodynamic data, ISO 50001 energy test standards, and EU CBAM Annex IV process-specific allocation rules.

3.1 Radiation & Bed Factorη_pack = 0.85

Thin-Bed Radiative Resistance

Thin-bed mesh-belt propagation assumes a standardized Bulk Packing Factor (η_pack = 0.85), accounting for radiative view factors and thermal contact resistance in discrete fastener beds to ensure <1.5% thermocouple variance.

3.2 Baseline Thermal CalibrationISO 50001 / GB/T 13338

Empty Holding Loss Decoupling

Empty-furnace baseline loss (E_loss) is empirically calibrated via ISO 50001 / GB/T 13338 Empty-Furnace Holding Tests at 880°C. Idle holding power (22.4% of total energy) is decoupled as facility overhead, eliminating per-batch overcharging.

3.3 Mass Conservation StreamError < ±2.5%

Scope 3 Circular Precursor Credit

Tracks mass conservation balance (100.0% wire rod = 88.2% products + 9.8% cold-pressed scrap + 2.0% scale loss). Briquetting scrap remelting is accredited under EU CBAM Annex IV with residual error bounded within ±1.8%.
