The gas-fired tilting furnaces in the KB product lines provide for high melting performance, making them ideal for melting operations. The use of high-quality insulation materials results in very low energy consumption. Designed with an exhaust vent over the crucible edge, these tilting furnaces achieve very high melting rates and optimum energy efficiency.

Standard Equipment for all Tilting Furnaces

KB ../12 for aluminum and zinc alloys
KB ../14 for copper alloys such as bronze or brass
Modern and powerful two-stage burner for high melting capacity and low maintenance operation
Exhaust gas discharge over the crucible edge
Multi-layer insulation for optimum energy efficiency and low external wall temperatures
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.
Incl. crucible
Electro-hydraulic tilting device with safe two-hand operation on the furnace
Uniform and precise pouring due to optimum pivot point
Emergency outlet for safe discharge of the melt in case of a crucible break
Integrated safety system which continues to operate the furnace at reduced power in case of malfunction in the thermocouple, in order to prevent the freezing of the melt
Over-temperature limiter for the furnace chamber with automatic reset to protect against over-temperature. The limit controller switches off the heating when the pre-set limit temperature has been reached and does not switch it on again until the temperature falls below the setting again.
Low-maintenance furnace chamber control with temperature measurement behind the crucible
Defined application within the constraints of the operating instructions

Standard Equipment for Tilting Furnaces KB ../14

Insulation with an additional wear-and-tear layer made of copper-resistant refractory concrete

Additional equipment

Additional Equipment for all Tilting Furnaces

Safety fence
Work platform or platform for easier charging
Collecting pan under the emergency outlet

Additional Equipment for Tilting Furnaces KB ../12

Side exhaust gas discharge including cover
Insulated exhaust gas diverter connecting piece (exhaust flue) for side-wall exhaust gas vent to a connected customer suction system
Crucible breakage monitoring with optical and acoustic signal
SMS-alarm message in case of crucible breakage
Bath control system (only when equipped with side exhaust gas discharge)
Process control and documentation via Nabertherm Control Center (NCC) for monitoring, documentation and control
