Thermal analysis instrument cup

Sample cup

The series of consumable thermal analysis sample cups are composed of a reasonable design cup body, quartz tube, and K -type thermocouple. Thermal analysis is measured and calculated due to its simple measurement and calculation of CEL, C, SI and other component parameters.

1. Carbon equivalent CEL

◆ It is expressed by the formula CEL % = C %+ Si / 3 %. When the iron -water sample just starts solidification, the captured liquid line temperature is directly related to this value.

2. Features:

◆ Reasonable sample cup design, solidly connected to the heat analysis plug -in

◆ Horizontal quartz protective tube design makes the response speed fast

◆ Wild pouring temperature is wide

◆ Good and stable cooling detection line

◆ High test rate

3. Carbon amount C

◆ It is determined by the two temperature values ​​of liquid -phase temperature TL and solid -phase temperature TS.

Four, silicon volume Si

◆ By measuring solid -phase temperature, SI can be calculated, and the silicon value can be calibrated by a adjustment, which is related to the carbon in the iron water.

Fifth, of course, heat analysis can also be applied to the following 3 aspects:

◆ Mogurize control, control the breeding through the determination of common coldness.

◆ By determining the temperature and coldness of the liquid phase, the mechanical and physical properties of iron water are predicted.

◆ The calculation of the ballization rate, based on the principle of relative thermal conductivity, can calculate the ballization rate of ball iron and iron water.

6. Model and its application:

◆ No (sample cup (KD-FQ): determine CEL, SG%, too cold degree

◆ Containing the sample cup (KD-F): determine CEL, C%, SI%
