- the further furnace muffle wall 13 has a further mounting element 25.
- the wide re mounting element 25 is designed as a hook.
- the further mounting element 25 is identical to the mounting element 24, which is why a further description of the further mounting element 25 is omitted.
- FIG. 6 shows a schematic flow diagram of a method for producing the induction furnace device 10.
- a positioning step 100 a blank 36 of the further surface element 21 is arranged on a blank 38 of the further wall element 17.
- an outermost circular section 42 is generated from regularly spaced further connecting elements 23 by means of a laser welding process. Alternatively or additionally, a plurality of outer circular sections could be generated in fixing step 110.
- the fixing step 110 follows the positioning step 100. Through the fixing step 110, the blanks 36, 38 are integrally connected to one another.
- connection step 120 the further connection elements are generated.
- the other connecting elements are also produced by means of the laser welding process. Circles from regularly spaced further connecting elements 23 who defines the distance of the circles from a center 40 of the further surface element 21. A circle 44 closest to the center 40 is generated first.
- the sales Binding step 120 follows the fixing step 110. The blanks 36, 38 after the connecting step 120 are shown in more detail in FIG.
