ISO 12986-1 carbonaceous materials used in aluminum prebaked anodes and cathode blocks - Part 1. Determination of flexural strength three-point method
Principle 3
Material testing machine by integrating the force - displacement signal to determine the make notched cylinder specimen fracture energy required.
Notched stored elastic energy can be reduced in a sample, and thus ensure a smooth and controlled crack propagation.
Using the same equipment and test equipment measured flexural strength and three-point method required, see ISO 12986-1.
There should also be measured by the length of the vertical displacement of the measuring device, and a data acquisition system capable of force - displacement curve integral
software.
4 Device
Adjustable to control the hydraulic loading rate. The maximum loading should 1kN above, load sensor accuracy is better than 5N.
Three-point method in compliance with ISO 12986-1 device. Displacement measuring devices should be 10mm of coverage, accuracy of better than 5μm. Notch
Sample loading station and signal recording apparatus shown in Figure 1.
The maximum loading of typical pre-baked anode is positioned between 500N ~ 1000N, corresponding to the amount of displacement as the load increases and the sample breaks
Different energies at substantially between 0.5mm ~ 1mm. Worldwide prebaked anode fracture energy typically around
200J/m2.
