Welding Flux Of Submerged ARC Welding

We are offering welding flux of submerged arc welding.
Description:
sj302 is a kind of silicon-calcium-type medium sintered flux,b∥w=1.0-1.1,mesh 10-40(2.0-0.45mm).either alternating or direct current can be used.the welding bead shapes well and the welding slag is "shor slag". And the welding seam has fine tough-ness and moisture and crack resistance.
Usage:
when applied to welding wires (h08a or h08mna),it can weld boilers,pipeline steel and common steel.
Cautions:
1.the oil soil,moisture,iron rust and other foreign substances must be removed from the welding joint.
3.the welding flux must be baked under 300-350℃ for 2 hours before welding.
