铸造生产中,受压铸件出现的气孔、缩孔、疏松而造成渗漏使之大量报废。据国外统计废品率铸钢为10～20％,铸铁为6～10％,铜合金为5～15％,铝合金为20％。国内则更为严重,各气缸头、阀体等报废率高达40％以上,某些缺陷在精加工时才发现,造成工对、原材料、能源、人力的严重浪费。铸件浸渗技术,是解决由于孔洞而造成受压铸件渗漏问题的有效工艺。我国六十年代中期就从国外引进这项技术并应用于生产,二十年来,许多工厂、科研所对浸渗设备的研究、浸渗剂的开发、工艺规范的探讨取得了显著的 Casting production, pressure casting appears stomata, shrinkage, loose and cause a lot of leakage caused by leakage. According to foreign statistics, the rejection rate of cast steel is 10 to 20%, cast iron is 6 to 10%, copper alloy is 5 to 15% and aluminum alloy is 20%. The domestic is even more serious, the cylinder head, valve body, such as scrap rate as high as 40% or more, some defects found in the finishing, resulting in workers right, raw materials, energy, human waste. Casting infiltration technology is to solve the problem of leakage caused by the hole casting pressure casting an effective process. In the mid 1960s, this technology was imported from abroad and applied to production. In the past 20 years, many factories and research institutes have made significant research on impregnation equipment, development of infiltrant, and discussion of process specifications
