Study on Surface Quality of Lead Clad Tin Bimetal Continuous Casting by Air Pressing Core-Filling
To provide theoretical basis and practical guidance of preparing copper clad aluminum composite rods by directly continuous casting, low melting point materials of lead and tin were selected to prepare composite rods of external diameter Φ12mm and inner diameter Φ8mm through adopting air pressing core filled continuous casting processing. The orthogonal tests consisting of three factors of melting lead temperature, continuous casting speed and inflation pressure at three different levels were designed to obtain arrangements of optimal process parameters that affected surface quality of bimetal casting rods in principle. The experiments showed that composite rods have excellent surface quality under the condition of melting lead temperature,375 , continuous casting speed, 10 mm/min, and inflation pressure, 0.03MPa.
