Electric furnace HTC series

chamberfor aeronautics

The high-temperature furnaces HTC 16/16 - HTC 450/16 are heated by vertically hung SiC rods, which makes them especially suitable for sintering processes up to a maximum operating temperature of 1550 °C. For some processes, e. g. for sintering zirconium oxide, the reduction of interactivity between the charge and the SiC rods, these models are more suitable than the alternatives heated with molybdenum disilicide elements. The basic construction of these furnaces make them comparable with the already familiar models in the HT product line and they can be upgraded with the same additional equipment. · Tmax 1550 °C · Dual shell housing with fan cooling provides for low shell temperatures · Heating from both sides via vertically mounted SiC rods · High-quality fiber insulation backed by special insulation · Long-life roof insulation with special suspension · Temperature uniformity at 1450 °C up to +/− 10 °C according to DIN 17052-1 see page 85 · Chain-guided parallel swivel door for precise opening and closing of the door · Two-door design (front/back) for high-temperature furnaces from HTC 276/.. up · Labyrinth sealing ensures the least possible temperature loss in the door area · Reinforced floor as protection for bottom insulation (distributed load 5 kg/dm2) · Vapor vent in the furnace roof with motorized exhaust air flap, controlled via the extra function of the controller · Stainless steel exhaust hood as interface to customer’s exhaust system · Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
