一种纳米改性含硼高铬铸铁耐磨堆焊自保护药芯焊丝的药芯
摘要：
一种纳米改性含硼高铬铸铁耐磨堆焊自保护药芯焊丝的药芯，涉及一种高铬铸铁耐磨堆焊自保护药芯焊丝的药芯。本发明是为了解决目前高铬铸铁堆焊合金耐磨性差的技术问题。本发明是由高铬铸铁粉、电解锰粉、硅铁粉、硼铁粉、石墨粉、铝镁合金粉和纳米改性剂组成。本发明的纳米改性含硼高铬铸铁型堆焊合金的组织由初生M7C3碳化物、共晶M7C3碳化物、马氏体和残余奥氏体构成。本发明的铬铸铁耐磨堆焊自保护药芯焊丝可用于矿山水泥立磨辊、磨煤机磨辊和磨盘、高炉料钟和料斗、破碎机锤头的修复制造等。
摘要（英）：

The invention relates to a flux core for a high-chromium iron hardfacing self-protection flux-cored wire, in particular to the flux core for a nano-modified boron-containing high-chromium iron hardfacing self-protection flux-cored wire. The flux core aims to solve the technical problem that existing high-chromium iron surfacing alloy is poor in abrasion resistance. The flux core is prepared from high-chromium iron powder, electrolytic manganese powder, silicon iron powder, ferro-boron powder, graphite powder, aluminum magnesium alloy powder and a nano-modified agent. The organization of the nano-modified boron-containing high-chromium iron surfacing alloy is composed of primary M7C3 carbide, eutectic M7C3 carbide, martensite and retained austenite. The chromium iron hardfacing self-protection flux-cored wire can be used for repairing and manufacturing a mine cement vertical grinding roller, a coal mill grinding roller, a grinding wheel, a blast-furnace top bell, a hopper, a crusher hammerhead and the like.
