The product established by the Hunan Provincial Science and Technology Commission in 1998 for the export of technology projects
                 
I. Overview
     This instrument is used to detect solid inorganic materials, high temperature expansion properties of metallic materials, especially corundum, refractory, investment casting using shell and core materials, ceramics, ceramic materials, porcelain clay, glaze, glass, graphite, carbon provides the essential means of testing, research, teaching and other inorganic materials, metal products performance. By the instrument can be completed to the sample line variable, linear expansion coefficient, the coefficient of volumetric expansion, the rapid thermal expansion, softening temperature, the sintering kinetics of the glass transition temperature, phase transition, the density change, the sintering rate control (RCS), and they change curve. User requirements can also be noted in the samples protective atmosphere, vacuum, vacuum degree 0.1MPa.
     Also applies to GB/T3810.8-2006 on Determination of linear thermal expansion of ceramic tiles,
                 Of GB/T16920-1997 pair of glass an average linear thermal expansion coefficient of determination,
                 GB/T3074 (1) .4-2003 on the determination of the coefficient of thermal expansion of graphite electrodes. .
 
 
Second, the technical parameters
1, the highest oven temperature: 1200 ° C, 1400 ° C, 1700 ° C by the customer choice.
2, the heating rate :0-100 degrees / minutes adjustable temperature control of computer programs.
3, a computer automatically calculate the coefficient of expansion, the expansion coefficient, the amount of linear expansion, acute and thermal expansion.
Automatically calculate the compensation factor and automatic compensation can also be manually corrected (Online).
5, automatically recording, storing, printing the number noted in print temperature - expansion coefficient curve.
The temperature spacing free to set minimum spacing of 1 ° C.
6, the expansion value measurement range: ± 5mm.
7, measuring the expansion of value-resolution 0.1-1um automatic calibration range.
8, the sample range (2-15) x (2-15) × (20-150) mm, square / circular shape can be.
9, imported linear bearing drive, expansion value excellent friction transmission, transmission accuracy and repeatability.
10, system measurement error: ± 0.1-0.5%.
11, the power supply voltage: 220V ± 10%, 2KW.
12, the instrument is equipped with a standard computer interface, associated with a general-purpose computer, all test operations are computer interface, easy to operate, easy to learn and provides a full set of software.
  (With carbon industry-specific detection software)
