Carl from British Reaction Research posts a new update on his oven progress for heat treating his aluminium tube bundled thrust chamber.
The tube bundle thrust chamber will be a weldment composed of 6082 and 6063 elements. In order to solution treat or artificially age this I have to raise it to a temperature of 525 degrees Celsius +/- 10 degrees and hold that for a specified time.
Using a repurposed pottery kiln, and custom temperature measurement system, the test proved successful.
After 25 minutes of running the 450 degree mark was breached and after 35 minutes a temperature of 520 degrees was attained. This finally settled down at 530 degrees and stayed there, give or take a degree either way.I didn’t think this was too bad at all, what with my initial misgivings about the accuracy of the control system and that the dial had been set quite roughly.
