Abstract

A kind of large-sized end enclosure inner wall overlaying electromagnetic induction heater, it is characterized on the outer surface of end socket, equipped with blanket layer is incubated, muff being housed on fusing head connection tube；Hinge retainer ring is housed, the outer collarette of hinge retainer ring arranges multiple hinge lock catchs on the boss at the top of end socket；Hinge turnbuckle corresponding with hinge lock catch is housed on the anti-deformation ring of end socket bottom, hinge is housed between hinge turnbuckle and hinge lock catch, installed between hinge enclose to induction cable.The problem of it solves traditional heated by natural gas and resistance-type heats end socket, and thermal conversion efficiency is too low, is particularly suitable for large-sized end enclosure inner wall overlaying heat treatment.

Description

Large-sized end enclosure inner wall overlaying electromagnetic induction heater

Technical field

Electromagnetic induction heating technology facility field is the utility model is related to, specifically one kind is in large-sized end enclosure built-up welding Cheng Zhong, the device heated using electromagnetic induction to its inwall.

Background technology

Large-sized end enclosure is in inwall weld deposit process and welding is front and rear, it is necessary to be preheated, rear heat etc. heats, tradition Method mainly have heated by natural gas and resistance-type heating two methods.Heated by natural gas, i.e., burnt using combustion gas frock natural Gas, the outer surface of end socket is heated, its thermal conversion efficiency is only 40% or so, and work with torches has serious potential safety hazard.Electricity Resistive heats, i.e., resistance wire is wrapped in into workpiece inner and outer surfaces, passes through resistance wire heating conduction, radiation workpiece, its hot-cast socket effect For rate only 50% or so, and resistance type heater part is easy to aging, service life is short, causes production cost too high.

Utility model content

The utility model heats large-sized end enclosure to solve traditional heated by natural gas and resistance-type, and thermal conversion efficiency is too The problem of low, design a kind of large-sized end enclosure annealing device using electromagnetic induction heating.

The technical solution of the utility model is a kind of large-sized end enclosure inner wall overlaying electromagnetic induction heater, its it is special it Place is, equipped with blanket layer is incubated on the outer surface of end socket, muff to be housed on fusing head connection tube；Equipped with hinge on boss at the top of end socket Chain retainer ring, the outer collarette of hinge retainer ring arrange multiple hinge lock catchs；It is equipped with the anti-deformation ring of end socket bottom and hinged lock Hinge turnbuckle corresponding to button, hinge is housed between hinge turnbuckle and hinge lock catch, installed between hinge enclose to Induction cable.

During work, insulation blanket layer is first packaged on end socket, and fusing head connection tube is covered with set；By the hinge at the top of end socket Retainer ring, hinge lock catch are installed, and hinge turnbuckle is attached on anti-deformation ring, and hinge is attached into hinge lock catch and hinge is drawn Between tight bolt, and hinge turnbuckle is adjusted by hinge locknig, finally sense induction cable around installing on hinge The both ends of cable connect with power supply can electrified regulation.

It is of the present utility model to have the technical effect that, using above-mentioned technical scheme, it is possible to achieve a kind of safe to use, hot-cast socket The high large-sized end enclosure inner wall overlaying heat treatment apparatus of rate.It is demonstrated experimentally that the thermal conversion rate of medium, high frequency electromagnetic induction heating is high Up to 95%, the intermediate frequency wire self-heating amount very little that inductor uses, operation under more than 400 DEG C of hot environment can be born, used Long lifespan, firing rate is fast, and heating-up temperature is high, and is non-contact thermal, is not easy to penetrate into impurity, heating to being heated end socket Uniformly, 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 structural front view of the present utility model, and the accompanying drawing that makes an abstract.

Status view when Fig. 2 is the utility model wrapping insulation blanket.

In figure, 1 cable, 2 turnbuckles, 3 hinges, 4 insulation blanket layer, 5 anti-deformation rings, 6 fusing head connection tubes, 7 retainer rings, 8 Lock, 9 boss.

Embodiment

Embodiment below in conjunction with the accompanying drawings, the utility model is further illustrated.

As illustrated, muff is housed on fusing head connection tube 6 equipped with blanket layer 4 is incubated on the outer surface of end socket；At the top of end socket Boss 9 on hinge retainer ring 7 is housed, the outer collarette of hinge retainer ring 7 arranges multiple hinge lock catchs 8；Preapre for an unfavorable turn of events end socket bottom Hinge turnbuckle 2 corresponding with hinge lock catch 8 is housed on shape ring 5, hinge 3, hinge 3 are housed between turnbuckle 2 and lock 8 Between install enclose to induction cable 1.

During work, insulation blanket layer 4 is first packaged on end socket, and fusing head connection tube 6 is covered with set；By the hinge at the top of end socket Chain retainer ring 7, lock 8 are installed, and turnbuckle 2 is attached on anti-deformation ring 5, and hinge 3 is attached into lock 8 and turnbuckle 2 Between, and adjust turnbuckle 2 and lock hinge 3, finally by induction cable 1 around installing on hinge 3, the two of cable 1 End connects with power supply can electrified regulation.

Claims
