二珪化モリブデン加熱と軽量耐火レンガ製断熱のある高温シルクハット炉とリフトボトム炉 最高温度 1800 °C

High-temperature top hat furnaces are ideal for applications that require high temperatures, such as ceramizing quartz glass. The furnace is designed so that the table can be accessed from three sides and also ensures ergonomic loading and unloading of large components. Complex structures and smaller components can also be charged safely. The furnaces can be equipped with a movable top hat or a movable table.

The basic furnace comes with one table. The system can be extended with one or more changeable tables, either manually or electrically driven, for example, to achieve higher throughput. Other additional equipment, like controlled cooling systems to short process cycles or the addition of a debinding package for debinding and sintering in one process provide for tailored solution for individual needs.

• Tmax 1600 °C, 1750 °C or 1800 °C
• Recommended maximum working temperature approx. 50 °C below Tmax of the furnace. Higher working temperatures will increase wear and tear.
• Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
• Top hat furnaces: electrohydraulically driven top hat with fixed table
• Bottom loading furnaces: driven table and fixed top hat
• Two-hand operation for manual hood/table movement
• Gently running, low-vibration spindle drive or electrohydraulic drive for larger models
• Motorized hood locking securing the hood in upper position
• Safe and tight closing of the furnace by means of labyrinth seal
• Heating from all four sides provides for good temperature uniformity
• High-quality fiber insulation backed by special insulation
• Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
• Side insulation constructed with tongue and groove blocks provides for low heat dissipation to the outside
• Long-life, robust roof insulation with special suspension
• Furnace table with special bottom reinforcement to accommodate high charge weights (distributed load 5 kg/dm²)
• Motorized exhaust air flap in the furnace roof, controlled via the extra function of the controller
• Heating elements switched via SCR‘s
• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
• Defined application within the constraints of the operating instructions
• Controller with touch operation P570 (50 programs with each 40 segments)
• NTLog Basic for Nabertherm controller: recording of process data with USB‑flash drive
• Freeware NTEdit for convenient program input via ExcelTM for WindowsTM on the PC
• Freeware NTGraph for evaluation and documention of firings using ExcelTM for WindowsTM on the PC
• MyNabertherm App for online monitoring of the firing on mobile devices for free download
