Product Description

Description of the machine :
The Automatic Refractoriness Testing Furnace is a precision instrument designed to determine the refractoriness of refractory materials, such as fireclay, high alumina, and other ceramic products. Refractoriness refers to the temperature at which a refractory cone deforms under heat, indicating the material's thermal stability and performance in high-temperature environments.
This furnace is equipped with a fully automatic imaging system that continuously monitors the deformation of the test cones during the heating process. The advanced optical camera captures high-resolution images in real-time and, through intelligent image recognition software, accurately detects the softening and bending behavior of the sample cones. This eliminates the need for manual observation and greatly improves test efficiency and repeatability.

The furnace chamber is constructed with high-quality insulating materials and features a precise temperature control system, allowing for uniform temperature distribution and stable heating up to 1750°C or higher, depending on the model. The user-friendly control panel and programmable logic controller (PLC) enable automated temperature ramping, dwell times, and image capture intervals, ensuring reliable and consistent test procedures.
This equipment is ideal for quality control laboratories, research institutions, and production facilities in industries such as metallurgy, ceramics, glass, and construction materials. It provides a standardized, accurate, and labor-saving solution for determining the refractoriness of materials according to international test methods such as ISO 528 and ASTM C24.
Luoyang Kunsheng Instrument Equipment Co., Ltd specializes in high-temperature testing equipment, and this model reflects our commitment to combining advanced technology with reliable performance. With integrated automatic image analysis and high-temperature operation capability, this furnace streamlines refractoriness testing and enhances productivity.
you can also choose optional Creep and RUL furnace KS-MFT-HRY-03 or KS-MFT-CRF03 model as following:

Test principle: Test the deformation of shell samples in 700-1600ºC. Method classification :
1) Ring method,Suitable for ethyl silicate and silica sol shell ;
2) Double fulcrum method, Suitable forWater glass shell
3) Single fulcrum method, Suitable for shell deformation at lower temperature
Sample quantity is 5, Sample shape and size:
       1) Circular ring sample, mm: Ø100×φ88×20
       2) Strip sample, mm:120 × 20 × 6
A thermal shock resistance test method based on Z direction to damage depth:
       Set up a measuring device or  tool which can measure the depth of the damaged end of the sample for measuring the value of Z direction to the damaged depth.  At the same time, mesure the area of the original area A1 of the XY direction of the end face before the test. Test the damaged area of the apparent surface A2 of the XY direction of the test face after each rapid hot quenching cycle. Test the area of the apparent damaged surface  A2 of the XY direction of the sample after every rapid heating and quenching cycle.
    Calculate  the damage rate σ of the heat end of the sample by the formula as follow: σ =A2/A1×100%
     Calculate the loss rate based on Z value for the end of  sample by the formula as follow: β(z)= A(z)2  / A1×100%
A(z)2  -The damaged area of XY with a certain Z direction to Z value
