Description

Top Hat Industrial Furnace

Typical applications of industrial top hat furnaces include soldering, the heat treatment of steels and alloys, and ceramics Sintering. The modular design of the static chamber furnace allows it to fulfil a number of different roles, and the versatility of the general purpose industrial chamber furnace makes it ideal for batch processing. 

The top hat industrial furnace provides the perfect temperature distribution thanks to the arrangement of the heating elements and the multilayer insulation included with this high temperature model.

The high temperature chamber furnace is most ideally suited to soldering and sintering.

The Carbolite top hat furnace has an hoist operated vertically moving hood for heat treatment. The moving hood design allows samples to be accessed from all sides. 

The Carbolite hood furnace has internal dimensions of Ø750 x 750 mm with the inner space being circular in design and the base plate having a convenient loading height of 385 mm from the floor. The Bell section is constructed from a high temperature Nickel alloy and the elements are spiral wound Fecralloy which surround the bell. 

The hood moves up and down automatically on guides on a Davy Morris 1000 kg two speed overhead electric hoisting unit for accurately positioning the bell.

The furnace is operated through its cycle with a multi programmable Eurotherm 902P series controller. The inert gas nitrogen atmosphere that can be used within the chamber is monitored and controlled by its own Systech oxygen analyser and the whole process can be monitored and recorded on the Yokogawa Data Recorder. 

Application Examples

annealing, ceramic injection moulding (CIM), debinding, debinding in air, degassing, drying, sintering, sintering in air, sublimation, synthesis, tempering
