Extreme cooling of steel shaft
Extreme cooling of steel shaft
(OP)
I do not whether this is the right forum. If not, please point it out.
I plan to shrink a 70 mm diameter x 1000 mm long shaft by cooling it with dry-ice (CO2) before fitting it to a 70 mm hole.
Dry-ice is supposed to be at -79 deg C. Assuming I get around -70deg C, what will be the shrinkage of the shaft diameter ? How do I calculate it ?
Thanks in advance.

RE: Extreme cooling of steel shaft
diameter = COE * delta T * original diameter
RE: Extreme cooling of steel shaft
Could you pls explain how you got two linear dimensions in/in ?
Also, delta T in my case would, asuuming an ambient of 30 deg C and CO2 temperature of - 70 deg C, be 100 deg C ?
