Furnace for high temperature test

Description

These three-zone split furnaces are designed for floor standing type universal testing machines and creep testing machines.

The elements of the split furnaces have been designed to achieve optimum performance and give the longest possible useful life. The heating elements are individually wound on MULLITE half tube sections, and provide three heat zones for excellent control of temperature gradients and reliable continuous operation up to the specified maximum temperature.

    High performance multi-crystal mullite refractory fabrics insulation is used to reduce heat losses and provide fast heat up rate. The specimen is heated primarily through radiation.

The exterior finish is stainless steel. Adjustable stainless steel latches keep the furnace sections locked together during tests and facilitate opening and closing of the furnace.

Ceramic closures at top and bottom fit closely around the loading bars and reduce heat loss at these points.

Each furnace has been designed for long life, good temperature uniformity and safe operation.
