Abstract
A brazing filler metal for hot-rolling brazing belongs to the technical field of brazing filler metals. Chemical components of the brazing filler metal in weight percent include 2-5% of Cr (chromium), 2-6% of Mn (manganese), 1-5% of Ni (nickel), 0.8-1% of Si (silicon), 0.3-0.5% of B (boron), 0.01% of C (carbon) and the balance Fe (ferrum). The brazing filler metal is banded, the thickness of the brazing filler metal ranges from 0.03mm to 0.05mm, and the width of the brazing filler metal ranges from 100mm to 400mm. The brazing filler metal has the advantages that the brazing filler metal is simple and convenient in use method and adaptable to compositing of more varieties of materials, production efficiency is improved, the welding strength of a composite plate can be improved, a welded surface is complete, product quality is fine, and all standards are higher than existing national standards.
