Task by task
We graded 10 tasks, listed here from most to least exposed. AI can't do any of them end to end yet. It speeds up 0 and leaves 10 to people.
| Task | AI exposure |
|---|---|
| Measure furnace walls to determine dimensions and cut required number of sheets from plastic block, using saws. On-site measuring and cutting requires physical presence. | 12% Needs a person |
| Mix specified amounts of sand, clay, mortar powder, and water to form refractory clay or mortar, using shovels or mixing machines. Physical material mixing, little meaningful AI help. | 8% Needs a person |
| Transfer clay structures to curing ovens, melting tanks, and drawing kilns, using forklifts. Forklift transfer of heavy clay structures is physical. | 6% Needs a person |
| Reline or repair ladles and pouring spouts with refractory clay, using trowels. Physical relining of ladle linings with hand trowels. | 4% Needs a person |
| Dry and bake new linings by placing inverted linings over burners, building fires in ladles, or by using blowtorches. Baking linings with burners and torches is physical work. | 4% Needs a person |
| Remove worn or damaged plastic block refractory linings of furnaces, using hand tools. Removing worn linings with hand tools is physical labor. | 4% Needs a person |
| Spread mortar on stopper heads and rods, using trowels, and slide brick sleeves over rods to form refractory jackets. Trowelling mortar onto rods and sleeves is manual work. | 4% Needs a person |
| Dump and tamp clay in molds, using tamping tools. Tamping clay in molds is manual, physical work. | 4% Needs a person |
| Chip slag from linings of ladles or remove linings when beyond repair, using hammers and chisels. Physical chipping of slag needs hands and tools. | 3% Needs a person |
| Climb scaffolding, carrying hoses, and spray surfaces of cupolas with refractory mixtures, using spray equipment. Spraying cupolas while climbing scaffolding is physical. | 3% Needs a person |

Questions about refractory materials repairers and AI
Will AI replace refractory materials repairers?
Unlikely. About 1 in 10 working hours go to tasks AI can already do, mostly measuring and cutting furnace wall sheets and mixing refractory clay and mortar. Relining, baking, and tearing out linings on site stay with people because they need a person physically in the furnace.
Which tasks is AI taking over in this job?
Measuring furnace walls and cutting plastic block sheets scores highest, at 12 on exposure, because AI can calculate dimensions and cut lists from drawings. Mixing refractory clay and mortar scores 8, since AI can work out the ratios of sand, clay, mortar powder, and water for a given specification. The hands-on fitting still needs a person.
Which tasks stay human?
Chipping slag from ladle linings with hammers and chisels scores 3 on exposure, because it takes hands and tools in a hot vessel. Spraying cupolas while climbing scaffolding also scores 3, and trowelling mortar onto stopper rods scores 4. All of this job's task weight sits in the stays human group.
How can refractory materials repairers stay valuable?
Keep doing the physical relining and baking work, since that is where the trade is hardest to automate. Record each lining job in maintenance management software so every furnace, kiln, and ladle carries a repair history. Track mix ratios in Excel, and get the OSHA powered industrial truck certification before running forklifts for clay transfers.
