Process for brass tube production by horizontal continuous casting rolling

The invention discloses a process for brass tube production by horizontal continuous casting rolling. The process mainly comprises smelt, heat preservation and cooling, horizontal continuous casting and cutting, oxidation layer removing and rolled tube annealing; the content of the raw materials is controlled, the rare-earth alloy is added during smelting, the grain refinement is improved, the processing performance is improved, the production of rolling is facilitated, and the yield is improved; and meanwhile, technological parameters are optimized and certain. According to the process for brass tube production by horizontal continuous casting rolling, the outer diameter and the wall thickness deviation are small, the precision is high, and the mechanical performance is high; and the process is suitable for horizontal continuous casting rolling production of the brass tube with all specifications and is easy to popularize. 本发明公开了种水平连铸轧制生产黄铜管的工艺；其主要工序包括熔炼、保温冷却、水平连铸、切割、去除氧化层、轧管退火；其中通过对原料含量的控制，并在熔炼时添加了稀土合金，改善晶粒
