低压铸造是一种历史较悠久的铸造方法,早在1910年就由E.F.Lake和A.L.J.Queneau所提出,并于1911年由Lake取得了用于巴氏合金的专利。但此法的发展却是最近20年的事,而且主要是60年代以后。其整个发展过程大致可分为三个阶段:第一个阶段是试验阶段(1910～1945年),在这个阶段中,继Lake之后,1920年法国首先用于铝合金,1933年德国A.E.G(通用电气公司)又取得专利,1937年英国使用惰性气体铸造镁合金。但由于当时生产率低,升液管、坩埚、模具均有问题和铝合金应用不普遍,所以未得到实际应用。第二个阶段是二次大战结束后至50年代末,在这个阶段中开始应用于实际生产,但很不
Low-pressure casting is a longer-established casting method proposed by E.F. Lake and A.L.J. Queneau as early as 1910 and patented by Lake in 1911 for babbitt. However, the development of this law has been the last 20 years, but mainly after the 1960s. The whole development process can be roughly divided into three stages: the first stage is the experimental stage (1910 ~ 1945), in this stage, following the Lake, 1920 France first for aluminum alloy, 1933 Germany AEG Electric Company) and patented, 1937 British use of inert gas casting magnesium alloy. However, due to the low productivity, liquid pipe, crucibles, molds and aluminum alloy applications are not common, it has not been practical. The second stage was from the end of the Second World War to the late 1950s and began to be applied to actual production at this stage, but not very
