Induction Furnace Development Update

We have made significant progress on the parametric Induction Furnace model in FreeCAD. This update covers the high-LOD enhancements, a focused core generator, a real-world Bill of Materials, and step-by-step build instructions.

Model Overview

We have developed two generator scripts to cater to different needs:

Full System Model

• Script: `generators/machines.py`
• Command: `python3 cli.py furnace`
• Description: A complete industrial setup including the structural frame, concrete platform, safety railings, hydraulic tilting mechanism, and full control panel.
• High-LOD Features:

      Hydraulics: Hydraulic Power Unit (HPU) with reservoir, motor, valve block, and hoses connecting to the tilt cylinder.
      Electronics: Detailed ZVS Driver module with PCB, heatsinks, capacitor bank, and choke inductors mounted on an open-frame rack.
      Cooling: Explicit water cooling loop with pump, radiator, fan, tank, and hoses.
      Hardware: Hex bolt heads at frame joints and pivot points.
      Casting: Double-crucible system (Inner Melting Pot + Outer Chamber) with a pouring spout and steel ramp.

Focused Core Model

• Script: `generators/induction_furnace_core.py`
• Command: `python3 cli.py furnace-core`
• Description: A simplified model focusing strictly on the functional components required for melting.
• Components:

      Induction Circuit (ZVS, Bus Bars)
      Heat Dissipation System (Radiator, Pump, Tank)
      Coil (Copper Tubing)
      Melt Chamber (Outer Crucible)
      Feeder (Hopper)
      Crucible (Inner Pot)

Bill of Materials (BOM)

We have sourced real-world parts for the core components. Prices are estimates.

Component	Model Specs	Real-World Part	Approx Price
Crucible	300mm Dia x 400mm H	Graphite Crucible #50-#100 (Industrial)	$150 - $300
Induction Coil	170mm Radius, 16mm Tube	5/8" Soft Copper Tubing (50ft Coil)	$80 - $120
Radiator	150x150mm	120mm Computer Water Cooling Radiator	$20 - $40
Pump	12V Centrifugal	12V Water Cooling Pump (PC/Industrial)	$20 - $50
Hydraulics	150mm Stroke	Hydraulic Cylinder 150mm Stroke	$50 - $100
Bus Bars	20x100mm Copper	Copper Bus Bar 1/8" x 1"	$30 - $60

Build Instructions

A detailed assembly guide has been generated.

Phase 1: Structural & Core

• Assemble the concrete platform and safety railings.
• Erect the main steel frame and install insulation blocks.
• Insert the Outer Crucible (Chamber) and Inner Crucible (Pot).

Phase 2: Induction & Cooling

• Wind the 5/8" copper tubing to form the coil and mount it over the chamber.
