二、80年代以来我国精铸生产概况 “特铸及有色合金”编辑部进行的行业调查表明,1988年我国精铸件的年产量为6万吨左右。若以每吨铸件平均售价1万元计,全国精铸件总产值约为6亿元人民币(合1.28亿美元),占铸件总产量的0.6～0.7％,总产值的2.2％。全国精铸厂点多达750～1000个,约为美国的3倍,厂点之多属世界之最。年产1000吨以上的有3家,100吨以上的115家,其余大多数(约80％)是年产100吨以下的小厂点。
Second, since the 80s of China’s casting production profile “special cast and non-ferrous alloy,” the editorial department conducted an industry survey showed that in 1988 China’s annual output of fine castings of 60,000 tons. If the average selling price per ton of castings 10,000 yuan, the country’s total output of refined castings of about 600 million yuan (128 million US dollars), accounting for 0.6 to 0.7% of the total castings, 2.2% of the total output value. As many as 750 to 1000 fine casting factories nationwide, about three times as much as the United States, as many factories as the world’s most. 3 with an annual output of more than 1,000 tons and 115 more than 100 tons. The majority of the remaining (about 80%) are small factories with an annual output of less than 100 tons.
