Heat treatment is a safe generic term, I believe. Perhaps a more specific term like thermal hardening, heat soaking, burn-in, or annealing may apply. The lining is probably refractory lining.
Linings can also be sintered (spiekane):
Sintering of lining:
• For proper sintering, always use K-Type thermocouples to achieve desired sintered lining.
• The end point of k-type thermocouples should touch the form to get an accurate temperature
reading.
• Do not steps out the holding temperature period given in sintering procedure.
• If possible, use ceramic blanket to cover the furnace top until melting starts. This will help
achieve a properly sintered lining from the bottom to the top of the furnace.
• Always fill the furnace to the top during sintering heat (Reference Figure 13/14).
