Standard:  JGJ18-2003  GB/T5293-1999
1. It is a type of Mid-Mn High-Si Low-F smelting flux;
2. Green to celadon with the grain size of 7-20 meshes. It is like transparent vitreous;
3. Application: particularly used in the electroslag pressure welding for vertical rebars;
4. Advantage: It's easy to start arc, to build slag pool, and to slag off. The process of electroslag is stable.
Chemical composition:

Cautions:
1.Before the construction of reinforcing, do try to pull parts used to determine the best parameters;
2.Reinforced fluctuation concentric, two plane to level off;
3.Should not dirt, grease joint and high corrosion;
4.Flux should not in the rain, H2O ≤0.1%;
5.Change of power supply voltage should adjust to welding standard
