Testing at temperatures up to 1000 degrees or above requires many new solutions. Here is list of some good products suitable at high temperatures: Heat-resistant thread ALF (Al2O3-SiO2) – can be used up to 1300-1400 degrees. It is good for attaching thermo couples as the mechanical properties are very good. Another benefit is that it is … Continue reading “High-temperature solutions”
Maybe I´m a control freak, but despite the integrated system, I´m still not comfortable leaving everything unwatched. We therefore also installed a camera (D-link) so we can follow the testing online. The camera can rotate in all directions and is easily controlled using the app.
Since we have other things to do than watching the rig, we wanted to design the system to be independent on our presence. If something goes wrong it should just fix it. I got help from Joakim Lindblom (JL Integration) who integrated the control system of the machine with the temperature- and gas control. If … Continue reading “Integration for safety”
The most difficult part of building this equipment was to make a chamber that is gas-tight but still allows for a test specimen to move at high temperatures. After many different designs, material choices and broken set-ups, we ended up with following design: Ceramic plates working as top and bottom of the chamber. The ceramic is … Continue reading “Gas chamber”
Today is a good day! I tested the chamber and it is confirmed to be gas tight! It took many different kinds of sealing solutions before getting here. The oxygen probe shows a satisfied value when testing in an argon atmosphere.
