Outer layer covers on the second heat insulation foam (14), be overlapped the junction of double thermal insulation cotton not, and fasten using glass fiber tape；
Step 14: selecting the consistent copper pipe of thickness, the adhesive tape of double-layer insulation high-temperature resisting superscribed on copper pipe, heat-insulated second
Cotton (14) outer surface replaces wire rod coiling by copper pipe, is formed electromagnetic induction coil (12)；
Step 15: uniformly placing more magnetic stripe columns (17) on the outer surface that the electromagnetic induction coil (12) made is formed,
Electromagnetic induction coil (12) periphery is cemented in by viscose, then wraps up one layer of second heat insulation foam outside in the good magnetic stripe column (17) of cementation
(14), outside the second heat insulation foam (14) finally wrapped up outside in magnetic stripe column (17) using aluminium sheet (15) roll it is curved surround a circle, and
The head and the tail joint of aluminium sheet (15) is connected using the adhesive tape (16) of insulation.
7. the manufacturing method of annular crack electromagnetic induction heater according to claim 6, it is characterised in that: the magnetic stripe
Column (17) in the prefabricated bar shaped glass-fiber-fabric sack of sewing, is formed whole by multiple small magnetic stripes by small magnetic stripe own wt
Root magnetic stripe column (17).
8. the manufacturing method of annular crack electromagnetic induction heater according to claim 6, it is characterised in that: the step
The mode of copper pipe coiling in 14 are as follows: one end is close around a circle closely one encloses, and one section is dredged around one times of caliber of coil spacing to 3 times of pipes
Diameter.
9. the manufacturing method of annular crack electromagnetic induction heater according to claim 6, it is characterised in that: the electromagnetism
Copper pipe the caliber 10mm-12mm, thickness 1mm-1.5mm that induction coil (12) coiling uses.
