Abstract
A kind of large-sized end enclosure inner wall overlaying electromagnetic-induction heating method, its feature includes dress and hangs insulation blanket, and in the fan-shaped insulation blanket of the appearance splicing two panels of end socket, two panels insulation blanket is connected into integral with silk ribbon；Hinge retainer ring is installed, end socket boss installs the circular hinges retainer ring that two semi-rings are constituted；Hinge turnbuckle is installed, multiple bolts, adjusting nut are installed on the anti-deformation ring of end socket；Hinge is installed, one end of hinge is connected with adjusting nut, the other end installs hinge lock catch, and hinge lock catch is coupled with retainer ring, regulation adjusting nut tenses hinge；Induction cable is laid, since at the top of end socket, cable is looped around end socket periphery, and is embedded into fixation in hinge, the upper and lower termination of cable is connected into heating with power supply.The problem of it is solved by heated by natural gas and low resistance-type heating thermal conversion rate, is particularly suitable for the heating of large-sized end enclosure inner wall overlaying and uses.
Description
Technical field
The present invention relates to electromagnetic induction heating technology field, specifically one kind is in large-sized end enclosure weld deposit process, profit
The method heated with electromagnetic induction to its inwall.
Background technology
Large-sized end enclosure is in inwall weld deposit process and before and after welding, it is necessary to be preheated, rear heat etc. heats, tradition
Method there is heated by natural gas and resistance-type to heat two kinds.Heated by natural gas, i.e., using combustion gas frock burning natural gas, to end socket
Outer surface heating, its thermal conversion efficiency is only 40% or so, and work with torches has serious potential safety hazard.Resistance-type is heated,
Resistance wire is wrapped in workpiece inner and outer surfaces, by resistance wire heating conduction, radiation workpiece, its thermal conversion efficiency is only 50%
Left and right, and the easy aging of resistance type heater part, service life are short, cause production cost too high.
The content of the invention
The present invention is solves traditional heated by natural gas and resistance-type heating large-sized end enclosure, and thermal conversion efficiency is too low
Problem, invents a kind of large-sized end enclosure heat treatment method of utilization electromagnetic induction heating.
The technical scheme is that, a kind of large-sized end enclosure inner wall overlaying electromagnetic-induction heating method, its special character bag
Include, dress hangs insulation blanket, installs hinge retainer ring, install hinge turnbuckle, install hinge, laying induction cable；
Dress hangs insulation blanket, according to the appearance of end socket, makes the fan-shaped insulation blanket of two panels（Two panels be optimal selection also can multi-disc, but
Splicing trouble can be increased）, the threading hole for splicing is dug in the edge of insulation blanket；End socket is arrived into the arrangement of two panels insulation blanket
Outside, connects integral by threading hole with silk ribbon by two panels insulation blanket, then around end socket broadwise winds a few with glass fibre belt, makes guarantor
Warm blanket laminating end socket surface；Meanwhile, single cap sleeve is installed additional on fusing head connection tube to be incubated；
Hinge retainer ring is installed, according to the size of boss at the top of end socket, a circular hinges for making two semi-rings compositions are fixed
Ring（Two semi-loops, are easy to contracting tensioning tight）, retainer ring is anchored at the top of end socket on boss；
Hinge turnbuckle is installed, multiple bolts are installed in uniform arrangement on the anti-deformation ring of end socket bottom, and on bolt
Equipped adjusting nut；
Hinge is installed, one end of hinge is connected with adjusting nut, the other end installs hinge lock catch, successively will hinge by correspondence position
Chain lock is coupled with the retainer ring at the top of end socket, then adjusts adjusting nut and tenses hinge, hinge is fitted to end socket appearance
On the insulation blanket in face；
Induction cable is laid, since at the top of end socket, cable is looped around to the periphery of end socket along broadwise, and be embedded into hinge one by one
In, cable is fixed by hinge, until the bottom of end socket is terminated, finally connected the upper end and lower end of cable i.e. with power supply
It can heat.
The solution have the advantages that, using above-mentioned technical scheme, it is possible to achieve one kind uses safety, thermal conversion rate pole
High large-sized end enclosure inner wall overlaying heating treatment method.It is demonstrated experimentally that the thermal conversion rate of medium, high frequency electromagnetic induction heating is up to
95%, the intermediate frequency wire self-heating amount very little that inductor is used can bear operation under more than 400 DEG C of hot environment, use the longevity
Life length, firing rate is fast, and heating-up temperature is high, and is non-contact thermal, is difficult to penetrate into impurity to being heated end socket, heating is equal
Even, temperature can be realized and automatically controlled, and accuracy of temperature control is high（±0.5℃）, the temperature difference it is small.
Brief description of the drawings
Fig. 1 is the structural front view of the present invention, and the accompanying drawing that makes an abstract.
Status view when Fig. 2 is present invention wrapping insulation blanket.
In figure, 1 cable, 2 turnbuckles, 3 hinges, 4 insulation blankets, 5 anti-deformation rings, the adapter of 6 public attention, 7 retainer rings, 8 locks
Button, 9 boss, 10 threading holes.
Embodiment
Embodiment below in conjunction with the accompanying drawings, the present invention is further described.
As illustrated, large-sized end enclosure inner wall overlaying electromagnetic-induction heating method includes：Dress hangs insulation blanket 4, according to end socket
Appearance, makes the fan-shaped insulation blanket 4 of two panels, the threading hole 10 for splicing is dug in the edge of insulation blanket 4；Two panels is incubated
Two panels insulation blanket is connected integral by the arrangement of blanket 4 with silk ribbon to the outside of end socket by threading hole 4, then with glass fibre belt around end socket
Broadwise winds a few, makes the laminating end socket of insulation blanket 4 surface；Meanwhile, single cap sleeve is installed additional on fusing head connection tube 6 to be incubated；
Hinge retainer ring 7 is installed, according to the size of boss at the top of end socket, a circular hinges for making two semi-rings compositions are fixed
Ring 7（Two semi-loops, are easy to contracting tensioning tight）, retainer ring 7 is anchored at the top of end socket on boss 9；
