Embodiment Construction

[0028] Due to the large size of large pressure vessels, fabrication shops usually build large pressure vessels in sections and then ship the sections of the piecewise-built pressure vessels to the site. For ease of description, the present invention refers to a section of a large pressure vessel constructed in sections as a large pressure vessel section 34 .

[0029] figure 2 The vertical heat treatment furnace for a pressure vessel manufacturing plant of the present invention is shown. Generally speaking, the vertical heat treatment furnace for a pressure vessel manufacturing plant of the present invention includes a holding furnace shell 33 and heat treatment facilities located in a pressure vessel manufacturing plant.

[0030] Wherein the crane of the pressure vessel manufacturer moves the large pressure vessel section 34 to be heat treated to the heat treatment facility, erects the large pressure vessel section 34 on the heat treatment facility, and then encloses the larg...

Abstract

The invention discloses an upright thermal treatment furnace for a pressure container factory, which comprises a heat insulation furnace shell and a thermal treatment facility positioned in the pressure container factory, wherein a traveling crane of the pressure container factory shifts a large pressure container section to be thermally treated to the thermal treatment facility, the large pressure container section is upright on the thermal treatment facility and is enclosed by the heat insulation furnace shell so that the thermal treatment facility directly sets the upright large pressure container section to be thermally treated as a hearth, and the large pressure container section is heated through thermal radiation, convection and conduction so as to carry out the thermal treatment on the large pressure container section. Through the thermal treatment for the large pressure container section, the technical problem that a large pressure container is easy to deform in the thermal treatment is solved.

Description

technical field [0001] The invention relates to post-weld heat treatment technology, in particular to a vertical heat treatment furnace suitable for pressure vessel manufacturing plants. Background technique [0002] Post-weld heat treatment of pressure vessels is the key process in the final stage of pressure vessel manufacturing and installation. The quality of post-weld heat treatment directly affects the overall internal quality of the pressure vessel. Unlike weld defects, post-weld heat treatment cannot be reworked, and heat treatment takes a long time and costs a lot. The effect of post-weld heat treatment is guaranteed by the post-weld heat treatment process. Therefore, the faithful execution of post-weld heat treatment process is the key to ensure the effect of post-weld heat treatment. The uniformity of heat treatment temperature, the rationality of holding time, and the accuracy of temperature measurement are all key. For large pressure vessels (such as towers in...
