Step 3, what 304 stainless steel belts are placed on flux-cored wire forming machine puts on band machine, by forming machine, steel band is rolled into U-type groove, then in U-type groove, add the medicine core powder that step 3 obtains, the filling rate controlling medicine core powder is 20%-25%, U-type groove is rolled closed by forming machine again, and be drawn to 1.2-2.0mm, obtain flux-cored wire;
Step 4, finally stretching with the flux-cored wire that step 3 is prepared by wire drawing machine, coil into disk, pack.
