Cement vertical grinding roll surfacing wire, Ming arc welding flux cored wire 
 Explain 

 HHBNb (Z) has excellent welding performance, weld appearance, spatter smaller features. Welding without using gas or flux conservation, which simplifies the welding process, saving the cost of welding accessories. Heap surfacing fine cracks, release stress, does not affect the normal use of low-impact mining conditions.
