Abstract

The invention relates to a gas quenching installation comprising a quenching cell ( 12 ), a buffer tank ( 10 ) which is intended to contain the quenching gas ( 6 ), gas connection means ( 32 ) which link the buffer tank ( 10 ) with the quenching cell ( 12 ) and gas supply means. Said gas supply means consist of an evaporator ( 8 ), the outlet ( 20 ) of which is connected to an inlet ( 22 ) in the buffer tank ( 10 ), and a high pressure storage tank ( 4 ) for the liquid-state quenching gas ( 6 ) which is connected to an inlet ( 16 ) in the evaporator ( 8 ), the connection means between the evaporator and the buffer tank having no gas compression means. The invention applies to installations used for the nitrogen quenching of steel parts.
