Sets for thermographic express-analysis of metal alloys
The sets are purposed for mass content control of the next elements: С and Si - in cast irons; С - in steels; Аl and Сu - in zinc alloys; Fe, Аl and Zn - in copper alloys; Si, Fe, Mg, Ni, Cu, Mn, Zn and Ti - in aluminum alloys,
as well as for determining of the next technological characteristics: inoculant efficiency; non-metallic inclusions quantity; porousity; shrinkable gas cavity volume; expansion of grains boundaries with the following estimation related other parameters.
The sets are completed with single-time immersion graphite and pouring sand or pouring multi-time (up to 1000 samples) painted metal cups with thermoelectric or optical-electronic thermotransducers.
2. Operation principle
It is based on registration and analysis of testing samples cooling curves, including temperatures of phase transformations "liquidus" and "solidus".
3. Main technical characteristics
|Absolute measurement error of pointed above elements mass content determination, %
|Analysis time, min
The sets have higher metrological characteristics due to use multi-time metal painted cups and statistical processing of primary measurement information. In comparison with other express-analysis technologies, thermography provides the best accuracy on C.
5. Теchnical-economic efficiency
The sets allow you to stably obtain metal products with determined properties at the lowest possible expenses.
6. Patent protection
