摘要：

针对传统爆炸复合用BFe30-1-1白铜板采用非真空熔炼铸坯直接轧制会导致内部存在夹杂物、疏松和分层等缺陷，以及在爆炸复合过程中出现的探伤不合格、爆炸开裂等质量问题，提出了一种采用真空感应熔炼结合电渣重熔双联法熔炼白铜铸锭的新工艺，然后再通过优化的锻造、轧制和热处理工艺对其进行后续加工，并对制备的白铜板进行多批次爆炸复合试验。结果显示：新工艺可以消除白铜铸锭的大量熔炼缺陷，提高冶金质量，明显降低夹杂物含量；经优化工艺处理后的白铜板的加工性能优异、微观组织均匀、耐腐蚀性好。爆炸复合试验显示，该白铜板的爆炸复合成品率更高，产品可以满足特种装备制造等领域的高端要求。

For the internal defects such as inclusions, looseness and delamination caused by the directly rolling of non-vacuum melting ingot of the traditional BFe30-1-1 copper nickel alloy plate for explosive cladding, and the quality problems such as flaw detection and explosion cracking occurred during the explosive cladding process, a new process for melting copper nickel alloy ingots using the duplex method of vacuum induction melting and electroslag remelting was proposed, and then subsequent processing was carried out through optimized forging, rolling and heat treatment processes,

and multiple batch explosive cladding test was conducted on the prepared copper nickel alloy plates. The results show that the new process can eliminate a large number of melting defects for copper nickel alloy ingots, improve the metallurgical quality, and significantly reduce the inclusion content. The copper nickel alloy plate after the optimized process treatment has excellent processing performance, uniform microstructure and good corrosion resistance. The explosive cladding test shows that the explosive cladding yield rate of copper nickel alloy plate is higher, and the products can meet the high-end requirements in special equipment manufacturing and other fields.
