SPLIT TYPE HEATING COIL, AND INDUCTION HEATING DEVICE AND INDUCTION HEATING METHOD USING THE COIL

摘要

PROBLEM TO BE SOLVED: To quickly induction heat a lengthy matter such as piping by providing an induction heating coil formed of separable and connectable lateral blocks. ;SOLUTION: A heating coil 1 for induction heating a body P to be heated is formed of a right block 2 and a left block 3 moved on a guide rail R by driving means 23, 33 in such a manner as to be separable and connectable. The right block 2 (the same may be said for the left clock 3) has a right heating coil divided body 21, and a gas jacket 22 on the outside thereof jet out a shield gas from a nozzle 9. The heating coil divided body 21 is formed of a semicircular coil body 24 and upper and lower connecting parts 25, 26 integrally formed on both the ends thereof, so that the left and right connecting parts can be mutually clamped. The coil body 23 is formed, of for example, a square pipe so that it can be cooled with water.;COPYRIGHT: (C)1998,JPO
