Box Annealing

แปลว่า(english) Annealing a metal or alloy in a sealed container under conditions that minimize oxidation. In box annealing a ferrous alloy, the charge is usually heated slowly to a temperature below the transformation range, but sometimes above or within it, and is then cooled slowly; this process is also called close annealing or pot annealing.

ACCUMULATOR

แปลว่า(english) A vessel, normally cylindrical, which is used to store fluid and gas for future release of the energy in the compressed fluid and gas.
