Double-layer horizontal cylindrical structure, inner wall made of 304
stainless steel with precision polishing, outer wall also 304 stainless steel,
water-cooled between walls to keep surface ≤55℃.
Technical Parameters
Furnace Type: Horizontal side-opening structure, with independent control cabinet on the right side.
Furnace Chamber: Double-layer horizontal cylindrical
structure, inner wall made of 304 stainless steel with precision polishing,
outer wall also 304 stainless steel, water-cooled between walls to keep surface
≤55℃. Equipped with vacuum ports, thermocouple holes, and electrode ports.
Furnace Door: Double-layer water-cooled flat door, inner
wall of 304 stainless steel with polishing, outer wall stainless steel,
pneumatic gear locking/opening mechanism for reliable operation.
Heating & Insulation System: Molybdenum alloy heating
strip mounted on alumina ceramics for annular radiation heating; full-metal
shielding (4 layers Mo, 2 layers 310S, 2 layers stainless steel, support
screens) ensures excellent insulation performance.
