一、平炉利用系数的飞跃增长我国解放前钢的年产量最高记录是1943年的92.3万吨,其中鞍钢占84.3万吨。抗日战争胜利后,在国民党的统治下,钢生产不但没有发展,而且连原有的企业也淹淹一息,到全国解放前后的1949年钢产量只有15.8万吨,这对人口众多的我国来说是一个微不足道的数字。 First, the flat furnace utilization factor leap growth China’s liberation before the highest annual steel production record is 943,000 tons in 1943, of which Angang Steel accounted for 843,000 tons. After the victory of the War of Resistance Against Japan, under the rule of the Kuomintang, steel production not only failed to develop, but also the original enterprises were flooded. By 1949, the steel output before and after the liberation of the country was only 158,000 tons, which for the large population of our country Is a trivial figure.
