ZT · SJ101H (fluorine-based)
Compliant: GB F48A2-H08MnA AWS F48A2-EA2-A2
Note: ZT · SJ101H is a special flux for fluor-alkali refractory and weathering steel; basicity is about 1.8, light gray spherical particles with a particle size of 10 to 60 mesh; the flux has excellent welding process performance, can be used for high-line energy welding, stable arc combustion, The weld seam is beautiful in shape and easy to remove slag. The weld seam has high strength, high toughness and good fire and weather resistance. It can be used for both AC and DC. In DC welding, the welding wire is connected to the positive electrode. Uses: Used with refractory steel welding wire, suitable for welding high-performance refractory and weathering steel, such as WGJ510C2.
Mechanical properties of deposited metal:

| -20℃ | |||
| 480-650 | ≥400 | ≥22 | ≥27 |
Requirements for weld metal inspection:
Grade I flux quality requirements:
⒈Flux content ≤0.10%
2. Mechanical inclusions in flux ≤.30%
Sulfur content of soldering flux ≤0.060%
Phosphorus content of 劑 flux ≤0.080%
· Precautions:
1. The flux must be baked at 350 ° C for 1 hour before use.
2. The rust, oil, water and other impurities must be removed at the welding place.
