Cryogenics Copper Block Quench

Cryogenics Copper Block Quench

Here we have two identical copper blocks Same wieght, both at ambient temperature and one is coated with a thermally insulating grease. We’re going to find out how long it takes to quench or how long it takes each of the blocks to go from room temperature to the temperature of Liquid Nitrogen in the bowl. First of all, the uncoated block “Quenching bubble sound” so the uncoated block took about four minutes to quench Now let’s see the coated block how long it should take This is thermally insullating grease it’s on all six sides of the block already smoothed in and here we go… “quenching sound” and there it is. the insulated on took only about forty seconds verses four minutes for the uncoated.
