ZT · SJ101H (fluorine-based)
· Compliant: GB F48A2-H08MnA AWS F48A2-EA2-A2
· Description: ZT · SJ101H is a special flux for fluor-alkali refractory steel; basicity is about 1.8, light gray spherical particles with a particle size of 10-60 mesh; flux has excellent welding process performance, can be used for high-line energy welding, stable arc combustion , The weld seam is beautifully formed, and the slag is easy to remove. The weld seam has high strength, high toughness, and good fire and weather resistance. It can be used for both AC and DC. During DC welding, the welding wire is connected to the positive electrode.
· Application: It is suitable for welding high-performance refractory and weather-resistant steel with refractory steel welding wire, such as WGJ510C2.
· Mechanical properties of deposited metal (according to GB / T12470-2003, F48A2-H10Mn2)

· Metal ray inspection requirements for welds:
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.
