Manufacturing Systems of the Mars Homestead Project Local Steel, Aluminum, and Glass Damon Ellender MHP Programming Team
Manufacturing Local Manufacturing is key to long-term planetary settlement
Requirements Steel Processing 400kg/day 1500K Aluminum Processing 25kg/day 1000K Glass Processing 200kg/day 1200K- 1400K Manufactured Products as needed for construction(i.e. Structural, wire,…) Dual use or Flexible equipment used where possible
Glass Process Floated on Tin, Pilkington Process, 2mx4m float tray, made from local brick, covered to protect from dust Cooled using CO2 in Lehr, 2mx2m, made from local brick. Rollers imported. Cut into 1m x 1mx5mm glass panels for transport and further cutting. Located Outdoors
LCC Steel Process Low Carbon Content (LCC) Steel is better for low temperature application All products made of 6mm Sheet or cast directly Provision for Rolling Strip depending on size of Steel Batch Located Outdoors
Strip Caster 6mm thick x2m wide Can be outdoors though dust may require enclosed(not pressurized) areas Pickling could also be done in enclosed area to ensure recovery of acids/caustics.
Typical Strip Casting Process All products made of 6mm Sheet or cast directly Provision for Rolling Strip depending on size of Steel Batch
Reference Earth Installations
Slab Caster For Context Not practical for amount of steel manufactured unless larger sections needed(i.e. rails) Batch Casting or Direct Chill better alternative
Aluminum Process Strip Casting possible using same process as Steel Direct Chill is also possible for Aluminum, not sure for Steel.
Aluminum Direct Chill Casting Ingots Poured Vertically Continuous Quench with Water or CO2 Once Mold is full, valve shuts, and ingot is rotated and pressed out by ram. Other material could use this process(i.e steel)
Annealing Furnace Located Outdoors Capable of 1000K Temperatures Capable of Controlled Cooling(using CO2) Approximately 5mx1mx1m made from local Refractory Heat Exchanger Imported(1m3, 100kg) Uses Steam from Nuclear Reactor for Controlled Heating
Material Transport Need Glass, Steel, and Al transported from Refining to Manufacturing Airlock Need Steel Rolls transported to Annealing Oven Need Finished Products transported from Manufacturing Airlock to Area of Use Rover or Automated Robot Carrier could easily be programmed to perform this function.

Slitter May be used for making wire ribbon as well.
Cutting device Diamond Saw Cuts both steel and glass
Tubing Mill-Formers Rolls strips into a tube and welds. Tubing out can be rolled or cut in lengths.
Coiler/DeCoiler Roll and Unrolls Tubing, Strip, Wire, and Cable. 200kgs per unit ~1mx2m floorspace
Steel Mill Control Room For Context Supervision of Process –Video –Instruments –Visual Programming of new process
Powder Coat Oven Finished Products Durable Epoxy Coating Can be used on Steel and Aluminum
