Controlled by computer, using CCD camera technology and artificial intelligence recognition technology, the characteristic melting temperature can be determined according to the national standard method based on the real-time graphics of the shape changes of the gray cone during the heating process; Deformation temperature (DT), softening temperature (ST), hemispherical temperature (HT), and flow temperature (FT).

A single experiment can measure 1-5 samples (including one standard sample), with a testing time of less than 3 hours. Novel heating devices and insulation materials are used to ensure that the furnace body is not damaged or deformed during long-term operation at a high temperature of 1520 ℃. Can print gray cone graphic results and temperature, and display the temperature rise curve on the screen.

Applied in industries such as electricity, coal, metallurgy, petrochemicals, coal chemical, environmental protection, cement, papermaking, geological exploration, and research institutes to determine the melting process of non single compounds such as coal ash without a fixed melting point.
