| description | The invention discloses a quenching method of a major-diameter thick-wall pressure gas cylinder. Based on a numerical simulation technique, under the premise that a major-diameter thick-wall pressure gas cylinder can obtain satisfactory tissues and an inner cavity can release pressure completely and according to the temperature change of characteristic nodes of the body of the pressure gas cylinder and distribution of tissues, the invention provides a quenching and cooling method in which intermittent mist spraying is carried out on the inner surface of the gas cylinder and continuous water spraying is carried out on the outer surface of the gas cylinder when the gas cylinder rotates. The gas cylinder rotates to improve the cooling uniformity of the gas cylinder. The inner surface of the gas cylinder is cooled in a mist spraying manner to reduce the temperature difference of the inner and outer surfaces of the cylinder body so as to reduce the quenching stress, improve the hardenability and reduce the deforma |
