Kiln furniture, retort components, thermocouple sheaths, belt-furnace supports, vacuum-furnace fixtures — heat treatment plant runs ceramic. Anderman supplies SiC, cordierite, mullite and alumina grades engineered for the cycling, atmospheres and temperatures the trade demands, with stock and partner production in both UK and France.
SiC, cordierite, mullite and alumina kiln-furniture grades in setters, posts, batts, plates, retort tubes and refractory hangers — covering belt furnaces, batch furnaces, vacuum furnaces and salt-bath setups from one specifier.
Atmosphere matters: oxidising favours SiC and oxides; reducing and vacuum push toward higher purity and different binders. Specification accounts for both atmosphere and temperature, not temperature alone.
Buffer stock in both UK and France against scheduled overhauls and unplanned breakages. The most-used kiln-furniture geometries available without lead time.
Belt and continuous furnaces use SiC setters, posts and batts for fast-cycle service — high thermal conductivity moves heat through the load fast, low expansion plus high strength tolerates repeated cycling. Cordierite is specified for high-thermal-shock zones and lower-cost setter geometry. Anderman supplies the full range of kiln-furniture shapes and bespoke sizes through partner production.
Batch and box furnace internals — hearth plates, refractory hangers, retort tubes — use mullite and high-alumina refractory grades. Specification depends on temperature, atmosphere and frequency of opening. Retort tubes for case hardening, nitriding and carbonitriding use specific grades for the relevant atmosphere chemistry.
Vacuum and controlled-atmosphere furnaces specify cleaner ceramic grades — dense high-purity alumina for hot-zone fixturing, BN for low-outgassing insulating components, AlN where thermal management is critical. Anderman supplies vacuum-grade ceramics with low outgassing and dimensional stability across temperature.
Salt-bath pots use high-grade alumina and aluminium-titanate components; quench-line supports for oil and polymer quenches use alumina-bonded refractory pieces resistant to thermal shock and chemical attack from the quench medium.
