A brief discussion on the internal control standards of seamless calcium wire

1. Chemical composition of calcium core:
Ca ≥ 97%

2. Nominal diameter of seamless calcium wire: 9.0 ~ 9.0 + 0.6mm; steel belt thickness: 1.0 ± 0.05mm;

3. Weight requirements of seamless calcium wire per meter: calcium core weight ≥ 52g/m, steel belt weight ≤ 210g/m

4. Degreasing and rust removal should be done before steel belt wrapping. The calcium core should be kept dry and no other magazines should be allowed to mix. The cored wire should be wrapped firmly, without leaking the core, opening the seam, removing the thread, or having a hollow package, and the surface should be oil-free and rust-free.

5. Packaging requirements: The weight of the iron frame should meet the general requirements of the cored wire. The outer contour of the product is tightly wrapped with plastic film, and there must be a non-fading label on the outside, indicating the name, main element content, size, weight, production unit, and production date.
