Description:
SJ**2 is a kind of sintered flux specially developed for the flux-cored wire in use of nitrogen-containing Martensite build-up welding. It may replace Japan-made NB**0M flux. The raw materials of the flux have high purity and the content of S and P is lower than 0.*2%,It possesses the following features:it has a good appearance of weld and a smooth and clean surface,without slag inclusions,without pores,and it has less loss of alloy elements,keeping the welding layers to have properties of erosion resistance,anti-ageing and abrasion resistance.
Usage:it may be used in the build-up welding fo high-temperature,thermal-cycle,heavy-duty conticaster rolls and hot-rolled rolls.
Cautions:
1.The welding flux must be baked for 2 hours at the temperature of ******0℃ before the build-up welding.
2.After the build-up welding, the used flux should be screened with ****0 mesh screen to remove small slags and fine powder mixed into it, ensuring the quality of the build-up welding layers.
