Vacuum Annealing Furnace
This vacuum annealing furnace uses resistance wire radiation heating. The furnace chamber uses a 310S stainless steel liner, which has good oxidation resistance and high cleanliness. The insulation material uses ceramic fiber wool, which has good thermal insulation performance and high efficiency, and energy saving. It is suitable for metal annealing, ceramic sintering, vacuum smelting, electric vacuum parts degassing, annealing, brazing of metal parts, and ceramic-metal sealing.

Why Hot Oil Tracing Still Earns Its Place in Process Plants A refinery must keep a sulfur transfer line above its melting point along a 400-meter pipe rack where no steam supply exists. A chemical plant must hold a polymer line at a stable 200°C through winter. In both cases, hot oil tracing delivers uniform, controllable heat without the condensate handling of steam or the electrical load of resistance tracing. Consider hot oil tracing when a site already operates a thermal oil heating system,...
