1981年高炉铁水直接浇铸钢锭模综合成本(与1979年冲天炉模相比)降低31.06元/吨,高炉铁水模使用寿命提高,节约价值达202.1万元;用炼钢铁水代替铸造生铁浇铸锕锭模,炼铁厂每年相当于增产一万多吨生铁,节约价值相当可观;各项节约折算成标准煤为12183吨,节约劳动力31人。两年来公司所得经济效益达657.4万元,节约标准煤二万三千多吨。
In 1981, the total cost of blast furnace hot metal directly casting ingot mold (compared with cupola furnace in 1979) was reduced by 31.06 yuan / ton, and the service life of hot metal mold for blast furnace was improved, saving value reached 2.021 million yuan; and casting actinium ingot instead of foundry pig iron Die, ironworks equivalent to an annual increase of more than 10,000 tons of pig iron, saving considerable value; the savings converted into standard coal 12,183 tons, saving 31 people labor. In the past two years, the economic benefits of the company reached 6.574 million yuan, saving more than 23,000 tons of standard coal.
