Abstract
The invention belongs to the field of manufacturing of legs of jack-up drilling platforms, and particularly relates to a heating furnace for a main chord of the leg. The heating furnace is characterized by comprising a base, a lid support, a lid, hearth heating elements, a hearth insulation device, hearth heating element vertical supports, main-chord supports and a coil. The base is connected with the lid support in a welding manner; the lid support is designed into a ring to support a lid according to the shape of the base; the lid is arranged on the lid support and is sealed with the hearth insulation device; the hearth heating elements are arranged on the hearth insulation device and used for heating the furnace inside; the coil is mounted in the middle of the hearth heating elements and the hearth insulation device; and the main-chord supports are connected with the base in a welding manner and used for supporting the main chord inside the furnace. By the heating furnace, different parts of the main chord can be heated uniformly to achieve hydrogen relieving process and postheat treatment of the main chord, thereby avoiding weld metal cracking of the main chord and guaranteeing quality of the main chord.
Description
Technical field
The invention belongs to the spud leg manufacture field that self-rising type creeps into platform, particularly relate to a kind of main shipboard tube process furnace.
Background technology
Pile legs of self-elevating drilling platform main shipboard tube, by after having welded of rack-plate and semi-circular plate, because main shipboard tube is at high temperature broken down into atomic condition from the hydrogen in welding rod, solder flux and air in welding process, is dissolved in liquid metal.During weld seam cooling, the solubleness of hydrogen in steel sharply declines, and because weld seam cooling is very fast, hydrogen has little time effusion and stays in weld metal.Can assemble at weld seam and weld bond place after for some time, under welding stress, weld heat-affected zone is caused to crack when gathering to a certain degree, the crackle caused due to hydrogen littlely occurred therefore is called delayed cracking postwelding is several often in several days, so need to disappear hydrogen process and postheat treatment to main shipboard tube after main shipboard tube has welded, be respectively used to eliminate the hydrogen of main shipboard tube inside and improve intensity and eliminate the possibility cracked.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming of the prior art, a kind of main side tube of spud leg process furnace is provided, main side tube of spud leg process furnace can to disappear hydrogen process and postheat treatment to three main shipboard tubes simultaneously simultaneously, because of welding, its inner hydrogen of existing is made to main shipboard tube and improves welding strength, avoid the generation of welding crack, ensure the quality of main side tube of spud leg.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of main side tube of spud leg process furnace, comprise base, bell support, bell, furnace bottom heating piece, furnace bottom heat-insulation device, furnace bottom heating piece vertical support frame, main shipboard tube support, coil pipe, described base and described bell support are welded to connect, described bell support arranges a circle for supporting bell according to base shape, described bell to be placed on described bell support and to seal with described furnace bottom heat-insulation device, described furnace bottom heat-insulation device is provided with furnace bottom heating piece, described furnace bottom heating piece completes the heat effect in stove, the described furnace bottom heat-insulation device laid in below can reduce furnace heat to external diffusion, described coil pipe is arranged in the middle of described furnace bottom heating piece and furnace bottom heat-insulation device, superfluous heat for producing in stove leads outside stove by vapor form, described main shipboard tube support and described base are welded to connect, described main shipboard tube support is for supporting main shipboard tube in stove, carry out separating to enable main shipboard tube and heating unit, ensure that main shipboard tube entirety is heated evenly, meet main shipboard tube to disappear the technique object of hydrogen process and postheat treatment, ensure the quality of main shipboard tube finished product.
Beneficial effect of the present invention is:
1, the present invention can make each position of main shipboard tube be heated evenly, and completes disappear hydrogen process and postheat treatment work to main shipboard tube, avoids the generation of main shipboard tube weld metal crack, ensures the quality of main shipboard tube;
2, inside of the present invention is provided with coil pipe, and application after inner surplus steam can being derived, improves the utilization ratio of the energy.
